Online car-hailing routes, I believe the algorithm should choose by itself

　　A few days ago, because the first car-hailing driver changed the route twice without permission and deviated from the navigation, the female passenger was frightened and jumped out of the car and was injured. So, what is the route design of the online car-hailing? A reporter from Beijing Youth Daily learned in an interview that the online car-hailing platform will consider time, distance and price factors at the same time, and finally recommend the route with the lowest price. In addition, some large platforms also allow passengers to choose the route by themselves. According to the regulations of our country, it is illegal for drivers to "take a detour" without authorization and will be fined.

　　Recently, many online ride-hailing platforms have not yet incorporated deviation route navigation into the reporting system, but if passengers have any objection to the fee, they can complain after getting off the bus. If it is a problem between the driver and the platform, the price difference can be refunded; if it is the passenger’s own choice, they will bear it. In addition, some analysts believe that in this incident, the aggregation taxi platform "Autonavi Map" used by female passengers should bear the corresponding responsibility, but so far, "Autonavi Map" has not issued an apology, and such aggregation taxi platforms should raise the entry threshold and strengthen the system construction.

　　Estimated route

　　Online car-hailing route planning, try to make the fare less

　　"Unlike the faster and smoother route recommended by self-driving, since online car-hailing will be billed based on mileage and duration, we also need to consider time, distance and price factors at the same time to recommend relatively fast and relatively cheap routes," said the head of the mapping division of an online car-hailing platform.

　　For example, Didi Express, the duration fee is 0.4 yuan to 0.8 yuan per minute, and the mileage fee is 1.45 yuan to 2.15 yuan per kilometer; the first car ride-hailing comfort model, the duration fee is 0.5 yuan to 1.2 yuan per minute, and the mileage fee is 2.8 yuan to 3.5 yuan per kilometer; the official model of Shenzhou special car, the duration fee is 0.55 yuan to 0.7 yuan per minute, and the mileage fee is 2.8 yuan to 3.92 yuan per kilometer. However, on aggregation platforms such as Autonavi taxi, passengers cannot accurately see the billing rules of each platform, only the "estimated route" is displayed.

　　Similar to the above-mentioned person in charge, another person in charge of online car-hailing operations also revealed to the Beijing Youth Daily reporter, "The route recommendation algorithm of the online car-hailing platform is similar. Because the underlying algorithm logic of the map merchant is similar, the online car-hailing platform essentially judges the map logic of the map merchant. After judging the route again, it preferentially chooses the route with a short distance, followed by the duration, and generally gives users a lower price route."

　　The above-mentioned people said that in many cases, "fast" and "close" are difficult to satisfy at the same time. The shorter distance is often a secondary road or branch road, with more traffic lights and more likely to be stuck in traffic; while the detour highway or ring road has stronger traffic capacity. As long as there is no extreme congestion, the speed is usually faster, but the time is shorter. Taking into account the user’s preference, so that the user can reach the destination safely and quickly, while making the driving distance as short as possible and the total cost as small as possible is the core principle of online car-hailing route planning.

　　In addition, during driving, the platform will also calculate the route every minute based on historical data and the real-time speed of the vehicle. When the new route is expected to save a lot of time and the fare increase does not exceed a certain number, such as 3 yuan or 5 yuan, the navigation will voice prompt, suggesting that the driver follow the new route after fully communicating with the passengers to avoid congestion as much as possible.

　　Modify the route

　　Online car-hailing platform launches route selection

　　Beiqing Daily reporter noticed that at present, in Didi Chuxing, Shouqi car-hailing and other platforms, the "route selection" function has been launched, that is to say, the client side provides passengers with multiple route planning, and passengers can modify the desired route by themselves.

　　However, because platforms such as Autonavi are aggregating taxi-hailing platforms, if you use this platform to hail a taxi, you cannot use the route selection function. "The system only supports modifying the destination internally, and the route can only be negotiated with the driver during the itinerary," Autonavi customer service said.

　　The insider also said: "What is more prone to problems is that passengers sometimes specify routes, but the cost or duration of the designated routes is higher than originally planned, and finally passengers are not satisfied and call to complain."

　　For this issue, the platform will generally make a judgment based on who designated the route, "If the driver completely follows the route designated by the passenger, the fee cannot be refunded; if the refund is made, there is a situation where the driver approves the refund or the passenger approves the refund. So when we train the driver, we will also ask the driver to make it clear when communicating with the passenger, ‘If you change the route and follow the passenger’s route, there may be more fees’, and let the driver remind you in advance." According to an online ride-hailing platform, that is to say, if it is a fee problem or route problem caused by the platform, the difference can generally be made up through complaints; but if it is the route that the passenger insists on, it is more difficult.

　　deviation from navigation

　　The driver deviates from the route and the platform will not be reported

　　Will the platform be alerted if the driver deviates from the navigation? "In fact, we have a function to report the yaw and remind passengers, but at present this function is not turned on because we are worried that excessive reminders will cause interference to passengers and cause unnecessary misunderstandings and communication." The person in charge of an online ride-hailing platform revealed.

　　Beiqing Daily reporter learned that the driver "detoured" without authorization, which is illegal. In the case of Hangzhou Shouqi’s car-hailing driver deviating from the route and causing passengers to jump off the bus, the official notice issued by the local investigation team mentioned that the online car-hailing driver’s behavior violated Article 37 (2) of the "Hangzhou Passenger Taxi Management Regulations". The transportation department will deal with the online car-hailing driver and Shouqi’s car-hailing platform in accordance with laws and regulations.

　　After investigation, the provisions of Article 37 (2) of the "Hangzhou Passenger Taxi Management Regulations" are as follows: Drivers shall abide by the following provisions in the process of engaging in online taxi services: According to the network platform to plan routes or passengers’ wishes to choose a reasonable route, and shall not take a detour. In addition, those who violate the provisions of these regulations shall be ordered to make corrections by the road transportation management agency, and a fine of not less than 300 yuan but not more than 3,000 yuan shall be imposed; if the circumstances are serious, their passenger taxi driver qualification certificate shall be revoked. In addition, according to the "Interim Measures for the Management of Online Booking Taxi Business Services" of the Ministry of Transport, online taxis such as detours will face a maximum fine of 30,000 yuan.

　　navigation function

　　The route of the map is often wrong

　　Many netizens said that in fact, maps are not omnipotent, and the route planning of maps is often unreasonable. For example, for some newly opened routes, the display is relatively lagging behind; for others, there are often problems with the direction of small roads.

　　Ms. Zhou, who lives in Beijing, said that the route in front of her house on the East Fourth Ring Road clearly indicates that you can only turn left and enter a one-way road, but the Autonavi map shows that you can only turn right, which not only makes it easy to hit vehicles traveling normally, but also increases the route by about 3 kilometers, which is a waste of time. "The same is true for taxis. The route planning has to take a detour. This can’t be blamed on the driver, but I don’t know where to give feedback."

　　In this first car-booking incident, the driver said he was a local and knew a newly opened route, but the navigation did not show it, so he wanted to turn in his direction twice. But the newly graduated female student could only rely on the navigation to analyze whether the driver was driving according to the route, so she developed fear after two deviations. In this regard, the lag of navigation is also a trigger for problems.

　　point of view

　　Taxi platforms should establish entry thresholds

　　"How reasonable is the route selection of online car-hailing? It is very simple, it is to let the previous personal preferences decide, become digital and platform-based, let big data to schedule, let big data to determine, and then choose the specific route. This is a basic logic and basic specification. The main online car-hailing platforms also do this. Only by doing this can you carry millions of orders per day on a large scale, standardised and systematized, so in this issue, we must use platform data instead of manual selection." Ding Daoshi, an independent Internet analyst, told the Beijing Youth Daily reporter.

　　In response to the incident of the female passenger jumping off the bus in Hangzhou, the passenger mentioned in the public statement that he was the vehicle of the first car-hailing car called through "Autonavi taxi". Ding Daoshi said: "Autonavi, as a platform party, must have been the first consumer to trust Autonavi. She used Autonavi to get the first car-hailing car. What kind of responsibility should Autonavi take in this process? So far we have not seen a voice or apology statement from Autonavi. I think this is very problematic."

　　"Like Autonavi Maps and other aggregation taxi platforms, it has access to many small platforms. From this incident, many small platforms have similar problems. To pass this incident, we must draw inferences from one another, especially the fourth-party service platforms represented by Autonavi Maps. Strict entry barriers and the construction of a compliance security system are required, otherwise more serious security problems may occur in the future." Ding Daoshi said.
