The navigator does not give a route what to do. Yandex Navigator - Failed to build a route: cannot be passed

Currently, car navigators are in wide demand among motorists. It is especially popular among car enthusiasts in big cities - the function of showing and avoiding traffic jams makes it a truly irreplaceable device.

Thanks to synchronization with several satellites, it allows you to quickly and accurately plot a detour route, indicate travel time, and has a lot of other useful functions. What if, after turning it on, it does not display the map, or begins to pave the way in a straight line, regardless of buildings and obstacles?

Why doesn't the navigator give me a route?

The reasons may vary. Factory settings - when you first start the navigator, you should keep it at hand, or even better, read the operating instructions in advance. Some foreign-made models enter the market with the language of the manufacturing country set by default, change the “language” parameter to ours, our native one!

Incorrect initial settings - when you turn it on for the first time, it searches for available communication satellites for further work. This process does not take much time, but the operation of the device is significantly affected - when traveling long distances, or when moving through mountainous areas, the signal switches to maintain stable operation.

An error with the message “Route not found” or “Unable to calculate route” on the screen can usually occur when you select too long a travel distance or, again, incorrect settings. Select the “system” item and set the use mode to “car”. In the “navigation” line we set the “minimum time” for choosing a path. With maximum settings, the route search will be the most accurate and shortest, but the calculation will take longer. It is more advisable to use this item for planning long-distance trips

Sometimes, due to a software glitch in the navigator, the map may be deleted and it will no longer pave the road. This may be due to the device being completely discharged or the power being turned off incorrectly. In this case, you should contact service center, where you will get the latest versions of road maps.

According to the company itself, Yandex.Navigator is used by 13 million users. Recently, the navigator spoke in the voices of Vasily Utkin and Optimus Prime, but users are still unhappy: some believe that the navigator builds suboptimal routes, leads straight through traffic jams, or often goes astray. In April, news appeared that the service would soon become partially paid, and in June a search for available parking spaces became available in the navigator. The Village asked Mikhail Vysokovsky from Yandex.Navigator to talk about how the service builds a route, where the traffic forecast comes from, and what innovations to expect.

Where does the navigator get data from?

Opening the navigator, we see how the arrow moves beautifully along the road line. But in fact, the GPS signal is not like that at all - it is something that constantly jumps: five meters to the left, 20 meters to the right. Therefore, accurately show the location and guide a person along the route - big task for any navigator.

The navigator receives location information from mobile device: First, the smartphone must understand its geographic coordinate and report it to the Internet service. For example, an iPhone has several sensors: GPS, GLONASS, data base stations cellular network and Wi-Fi. The iPhone automatically analyzes this and gives the application a specific coordinate, so to speak: “Friend, I know for sure that your coordinates are like this.” How exactly the device determined them - via GPS, GLONASS or cellular network - is left to the discretion operating system. With Android it’s a little easier: you can find out where the signal is coming from.

After the coordinates are received from the device, you need to understand where the car is actually moving and what road it is driving on. The navigator receives data about this every few seconds. This is not an easy task, especially if the user is at a difficult junction. The algorithm makes a number of assumptions about where the user actually is. If several signals have been received that a person is driving closer to the backup than to the main road, then the navigator transfers him to the backup. At some point, having analyzed all previous signals, the system may change its decision - then the arrow will be on the main road. At each moment of time, this is making a decision based on the user’s route, previous signals and new ones that arrive.

"Yandex.Maps" and "Yandex.Navigator" use identical algorithms. Sometimes their forecasts and choice of routes diverge: this can happen because even nearby devices can receive slightly different coordinates or build a route with a difference of several seconds. Despite the fact that the platform is single, different teams work on geoservices at Yandex. The Navigator team is responsible for the entire automotive theme and routing - this makes it easier to synchronize.

How does a navigator build a route?

While the user is building a route from point A to point B, the system considers a large number of alternatives and chooses optimal options route. There is a road graph - this is map information where maneuvers are marked: where you can turn and where you cannot. The system goes through different options for combining maneuvers, giving priority to the optimal one in terms of time, and suggests this route, but taking into account traffic jams and current closures. In addition, the navigator usually offers two other routes, they should be different in content - we will not offer exactly the same route, but with a stop at a gas station to save 30 seconds.

Currently, Yandex.Navigator offers a maximum of three route options. We can offer 50 different routes, and let the user think what to do with them. But the results of usability testing show that when a person is given a huge number of routes, it is quite difficult to understand which one to actually choose.

While driving, every two minutes the navigator checks to see if there is a faster route. However, there is some limitation on when this route can be offered. The situation in the city is changing quickly, and if the navigator keeps saying: “We found a route 30 seconds faster,” it will be quite difficult. Now the system offers an alternative if the time savings is more than five minutes, when there is little time before the maneuver. At the same time, if even 30 seconds are important to a person, he can request to search for a quick route himself by going to “Browse” on the application panel.

Now the algorithm is designed in such a way that it optimizes time for each specific user, that is, it builds a route specifically for you. And it does not take public welfare into account when trying to divert flows. (There have been suggestions on the Internet that Yandex.Navigator is trying to globally influence the transport situation in Moscow. - Ed.) But, since there are many users, we inevitably influence the situation on the roads. A few years ago, the navigator was such an elite club - there was a small proportion of people who used the navigator, and the rest were Muscovites. Then users saw: there are traffic jams here, but there are no traffic jams here - and the navigator had no effect on the situation on the roads. Now, when millions of users every day build routes with a navigator, and we tell them that there is no traffic jam here, everyone comes here, and, probably, a traffic jam may appear because of this.

How does the navigator take into account traffic jams?

Every time users travel with the Yandex.Maps or Yandex.Navigator application, they transmit anonymous information about their movements. In total, 13 million people use our navigator in Russia.

Receiving this data, we automatically analyze it on the server and understand that on a certain road, if people are driving slower, there is most likely a traffic jam. We take this information into account and communicate it to users in two ways. The first is a color indicator in the application, the second is that traffic jams are taken into account in the time predicted by the navigator. This is completely automatic system: Data is updated every minute.

Some time ago we built a route, taking into account only current traffic jams. Although in fact the situation is constantly changing, and rush hours are a difficult time for all navigators. Traffic grows chaotically, and the navigator, when constructing a route based on current traffic jams, does not take into account new ones, and because of this, lies in time. Therefore, we are now experimentally taking into account the traffic forecast for the next hour. For such a forecast, we have two factors: the first is the situation in past weeks on this day of the week and at this time, and the second is the situation on the roads at the moment.

After we have predicted traffic jams, we analyze how well we did it. If a person reached the end with the navigator, we know how long it took him to do it, and we can compare it with the navigator’s promise. Our second metric is called “Yandex is lying.” People often complain about how the navigator behaves in Conversations. We count the share of conversations in which Yandex is criticized, according to keywords“lies,” “tells a lie,” and all sorts of other curse words. When we display something inaccurately, we see a sharp rise in such conversations - it turns out to be a rather sensitive instrument.

Why does the navigator act up near the Kremlin?

The navigator, like other geolocation applications, receives information about the current location from the device. And he cannot determine how reliable they are. The device does not report that these are bad coordinates, it behaves in a standard way - only the coordinates are not on the Kremlin embankment, but somewhere else.

In a simple way navigator with change GPS signal can't do anything. It behaves according to the principle “what the device says, that’s what I do.” When at the end of last year we realized that the situation on the Kremlin embankment was not a one-time story, but a regular problem, we came up with new algorithm. Now, if the navigator sees that the coordinate is changing very quickly (for example, the user seems to have flown at a speed of 200 kilometers per hour from one point to another), the system blocks this movement. The navigator arrow does not move anywhere: at this moment, route guidance does not work and the exact position is not determined, but a person can at least navigate on the map where to go, and not find himself in Vnukov’s gray zone. This works when "teleportation" occurs. Unfortunately, there are more complex schemes. Sometimes the coordinate can be transferred not tens of kilometers, but to the next street, then a little more, and then another. In this case, the navigator cannot understand whether this is a false reroll or whether the last value should be trusted.

How changes in the city affect the operation of the navigator

In fact, algorithms need constant improvement. It would seem that he did it - and everything should work endlessly. In general, this would be the case, but the world is constantly changing. In addition to the story of the Kremlin embankment, there are other cases. For example, a year ago in Moscow a lot of dedicated lanes appeared for public transport: taxis drive along them, but violators also drive along them. In this case, we see that some of the signals are stuck in a terrible traffic jam, and some of the signals are passing through calmly. The algorithm automatically identified this as a traffic jam and highlighted it in yellow - it turned out to be stupid. We have learned to identify signals that differ from the main flow. But the “My Street” program is quite difficult to take into account, because the situation changes every day. Today there is renovation here, and tomorrow on the next street. We take it into account using standard methods- note and check all messages about overlaps.

How a navigator searches for free parking

One day I was going to the theater. Imagine the situation. The performance starts at 19:00, after the third bell it is difficult to enter. I looked at the traffic jams and decided to go by car. I arrived at the final destination, the navigator reported that we had arrived, but in fact I had not arrived anywhere: I was still driving the car, I saw the theater on the right, but this did not help me at all. Then I see that there is a parking lot on the left, I drive closer and find a sign “For disabled people only.” There is also parking on the right, but it costs 200 rubles. I kind of want to park, but I'm hoping to find a cheaper place. While I’m thinking about where to go, it turns out that I’m standing at a pedestrian crossing, and they’re honking at me from behind. A lot of problems arise. Then I turn into the nearest alley and find myself in God knows where. In the end, I somehow leave the car and run to the theater, but this is a super uncomfortable story.

We realized that parking means new traffic jams. If previously the main problem for Muscovites was traffic jams, now they still remain a problem, but at the same time, navigators have learned to predict them. No navigator has helped with parking before. We did five things. First, when approaching a destination, they began to show where parking is and is not allowed. At this moment, the person is stressed and often does not see the signs, and if everyone is standing, this does not mean at all that parking is allowed here - maybe they have covered up the numbers with pieces of paper. The next thing is that when a person understands where he can park, he wants to park not for 200 rubles. That's why we started showing where and for how long you can leave your car. Third, when approaching a destination, the navigator suggests a special route so that the user can drive along nearby lanes and be more likely to find parking without going far from the destination. Otherwise, you can turn into a one-way lane and then end up on the Third Ring Road.

But ideally, the user should see where it is actually free. And this is a very complex story. There simply is no such data. We are trying to detect with our algorithms that space has become free. Now the navigator on Android in the background provides us with information - we record that a person has changed the method of transportation from automobile to pedestrian and vice versa. We conclude that he most likely left or took the car. We overlay this data on a parking map and show available spots within five minutes. But now we do not guarantee that it is really free: the place can be occupied in 30 seconds. In this case, the probability of finding free place still high. This feature is already available to users: you can turn on the parking layer and see green dots. After a person has parked, he still needs to pay for parking - we have integrated with a payment service and are testing the payment function.

We are looking for parking data different ways. There is open data from the Department of Transport, but it is often out of date and due to reconstruction in the center, it is constantly changing. We are rechecking them. Data about other parking lots, for example when shopping centers, we collect manually using a directory of organizations.

Will the navigator be paid?

We feel that the navigator should not do everything the same for everyone. We are currently working on offering special solutions to professional navigator users. For example, the navigator should show taxi drivers the traffic situation on dedicated lanes, and truckers should build routes taking into account where they are allowed to go and show the axle load. Now many logistics and transport companies have applications from which our navigator is automatically launched. Previously, we did not know what kind of companies they were and what they wanted. Maybe for a courier company it is necessary to display 50 points on a map and show the optimal route between them. We asked them to register in the system and are now trying to understand what the demand is for. The nearest thing that will appear is navigation for taxi drivers using dedicated lanes. For ordinary users Yandex.Navigator will remain free.

What innovations to expect

Sitting in a room, you can talk as much as you like about how the navigator is useful or not useful. But behind the wheel the situation changes. Therefore, we regularly test the system, doing rides with users and seeing where the navigator works well and where it does not. In addition, we read reviews a lot - through the support service, in stores and in social networks. If some problem comes to the fore, we make a prototype of the function, arrange races, and then test it with some users.

Recently it has become possible to build a route entirely by voice, without using your hands. There are statistics that say that using a smartphone while driving increases the likelihood of accidents by 24 times. Now, when you get behind the wheel, you can say: “Listen, Yandex, let’s go home.”

Only the search for entrances appears. Navigating the last mile, when you need to understand which side of the house to approach from, where there is a barrier and where there is not, used to be quite difficult. Now in the "People's Map" - in a special editor, where users can independently put on maps Additional information, - we announced a week of entrances. If the entrance has been added to this map, then the navigator will be able to find it now. When there is a lot of data, we will add a more convenient search method.

In Russia, users often complain about poor connections. Now you can only download maps in the navigator, and we are actively working to make it possible to build a route offline.

We want to be more than just a dry tool that leads through traffic jams. Therefore, new voiceovers appear in the navigator: previously there were the standard voices of Oksana and Dmitry, then Vasily Utkin and Fyodor Bondarchuk, Optimus Prime and Bumblebee from Transformers appeared. The recording of the stars' voices lasted several hours. When the navigator says, “Turn right in 200 meters,” it’s actually five pieces glued together. Synthesized machine voices are now available: they differ from regular voices in that they can say many more phrases, such as street names. New voices will emerge for different audiences.

Now you can call a tow truck from the Navigator application. This is not a directly related thing to the navigator. But we are going to develop in this direction. Having a problem with your car? Go to Navigator. Do you need to pay for parking? Go to Navigator. Don't know what to do? Go to Navigator.

Many of us use navigation programs. They will show you the way to the desired point, inform you about traffic jams, and tell you about the distance and travel time. One of the most popular domestic developments in this regard is the application from Yandex. Its capabilities are already used by more than 16 million users in Russia and more than 4 million around the world. But since about the beginning of 2019, when trying to build a route from point A to point B, Yandex.Navigator users are increasingly encountering the following message: “Failed to build a route: cannot be passed”. What to do in such a situation? We'll tell you in our material.

“It was not possible to build a route: you cannot pass” - the essence and causes of the problem

The message that it is impossible to create a route has been recorded by users from time to time since 2012, when the application first appeared on the market. Around the beginning of 2019, the problem became widespread and began to appear everywhere.

This is due to the following factors:

The application version on the user's device is out of date;
The maps used by the application are outdated;
Yandex does not have sufficient information about the type of area in which the user is located (most often this happens abroad);
The navigator does not work in some specific locations. For example, it does not work well in the Kremlin, which is caused by special security measures and the operation of a transmitter that replaces satellite signals;
There is a failure of the service (application) itself, the presence of which the Yandex service may not even know. It can take quite a long time to eliminate the dysfunction.

Let's figure out how to solve the problem “Could not build a route: cannot be driven” on your device.

Check your internet connection

First of all, make sure that your Internet connection is stable. Launch your browser and try visiting a few familiar sites. If the transition occurs without any problems, move on.

Check the activation of GPS and access to geodata of the Yandex.Navigator application

Go to your device's settings and make sure that access to GPS and location data is enabled. This is important for correct route construction.

Check if you have access to geodata

Update your auto app version

We recommend updating your version of the Yandex.Navigator application. According to Yandex officials, older versions of the program are not compatible with the new functionality of the application. Therefore, if you use it on Android or iOS, update your version to the latest and most current one. Then you will be able to create paths without errors.

Install the latest version of the application

Move the starting point of the route a few hundred meters on the map

To correct the error about the impossibility of constructing a route, Yandex specialists recommend moving the starting point several hundred meters from the original one. Walk (drive) a few hundred meters in any direction (closer to large populated areas). After this, try again to build the route you need.

Reinstall Yandex.Navigator

If not one of the listed methods does not help, completely reinstall the application. Remove the program from the device, restart the system, and then install Yandex.Navigator again. This can help get rid of the error of incorrect path construction.

Report a problem with the route to Yandex technical support

If you are using the latest version of the program, and it still displays a message stating that it is impossible to drive to the specified address, we recommend reporting the problem to Yandex technical support.

For this:

Go to the website https://yandex.ru/support/navigator/feedback.html;
Click on “Feedback”;
Enter your name, email, check the box next to “ Technical problem", and describe its essence;
Enter the captcha below, then click on “Submit” and wait for a response from a specialist.

Fill out the feedback form

Typically, it can take Yandex several weeks to adjust (debug) maps. According to the developers, this is due to a rather labor-intensive and lengthy process of working with cards, so you should not expect instant results.

Conclusion

When the message “Could not build a route: cannot be driven” appears in Yandex.Navigator, we recommend that you first update the program to the latest version. Changing the starting point of the route by a few hundred meters also helps, which allows the program to rebuild the route and avoid errors. Use the tips we have listed, they make it possible to fix the problem in question on your gadgets and PC.

Yandex maps - convenient service, which will help you not get lost in an unfamiliar city, plan a route, measure distances and find the right locations. Unfortunately, there are some problems that may prevent you from using the service.

What should I do if at the right time Yandex Maps does not open, showing an empty field, or some of the map functions are not active? Let's try to figure it out.

Using the right browser

Yandex Maps does not interact with all Internet browsers. Here is a list of browsers that support the service:

Google Chrome

Yandex browser

Opera

Mozilla Firefox

Internet Explorer (version 9 and higher)

Use only these browsers, otherwise the map will appear as a gray rectangle.

Enabling JavaScript

If some of the buttons on the map (line, route, panoramas, layers, traffic jams) are missing, you may have JavaScript disabled.

To enable it, you need to go to your browser settings. Let's look at this Google example Chrome.

Go to settings as shown in the screenshot.

Click "Show advanced settings."

In the Personal Information section, click Content Settings.

In the JavaScript block, check the box next to “Allow all sites to use JavaScript”, then click “Done” for the changes to take effect.

Correct blocking setting

3. The reason that the Yandex map does not open may be the setting of a firewall, antivirus or ad blocker. These programs can block the display of map fragments, mistaking them for advertising.

The size of Yandex Maps fragments is 256x256 pixels. You need to make sure that their downloading is not prohibited.

Here are the main causes and solutions to problems with displaying Yandex Maps. If they still do not load, contact Yandex.

While collecting information on the Internet, I came across news from the Yandex company. The whole point is this. Yandex launched an application for iPhone and smartphones running Android – Yandex.Navigator.

This is a very interesting and most importantly practical application that will save a lot of time.
In order to start using Yandex.Navigator, you need to enter your home or organization name and click: Let's go!

The application knows about the situation of traffic jams throughout Russia and Ukraine. The database contains more than 500 cities. As soon as something changes in the city, it changes in the application.

Updates for cities happen quite quickly. But this is not the main advantage of the program.

If our car leaves the route, the navigator will rebuild the route (as if adapting to us) and launch a new route scheme.

There is also very important function– warning function. Something always changes on the map: traffic jams disappear, or vice versa appear. The voice prompt or on-screen prompt will work instantly.

She will alert us about these changes. And we will be able to take further actions based on these things.

This program also remembers the paths we have entered. Therefore, in order not to enter the same thing a hundred times, you can find these paths in your favorites.

Now let's get back to the topic of traffic jams. Yandex Navigator shows not only how to travel the shortest route, but also the freest one. Often the main factor in choosing a road is the presence of traffic jams.

Traffic jams are nothing but time, and time is money. Therefore, if you want to save money, then this application is for you.

Yandex.Navigator provides information about nearby restaurants, bars, fast food, pharmacies, groceries and much, much more. For example, it happens that the car runs out of gas. The navigator will display the nearest gas stations. It only takes a few steps.

In order to download this application, we will use the official website: http://navigator.yandex.ru/

Now in the right corner we select one of the proposed options. Either we indicate the mobile number and we are provided with a download link, or we go to the site through the phone’s browser.
