Information processing method for traffic management
Technical Field
The invention relates to the technical field of traffic management, in particular to an information processing method for traffic management.
Background
Currently, a road navigation system implements vehicle navigation based on mutual communication between a mobile terminal, a satellite navigation system, and an information processing center.
For vehicles traveling on an expressway, a road navigation system (such as a Baidu map and a Gade map) prompts a driver of a vehicle behind for a congested road section in the following way:
when the vehicle runs to a preset distance away from the congestion road section, the mobile terminal (such as a mobile phone) prompts the driver that the congestion road section exists in front of the driver in a voice broadcasting or character pattern display mode.
However, the above prompting method of the navigation system in the prior art has the following defects:
1. the navigation system merely prompts the driver to have a congested road segment ahead, but does not assist the driver in selecting a more optimal driving route for congestion ahead.
2. The navigation system prompts the rear vehicle according to the distance from the congested road segment, and for example, the navigation system sets: when the rear vehicle travels 5 kilometers away from the congested road section, the guidance system prompts the vehicle to be congested at 5 kilometers ahead, however, in some cases, when the rear vehicle travels 5 kilometers away from the congested road section, the vehicle has no alternative route, and there is no way to bypass the congested road section even if the congestion ahead is known.

Compared with the prior art, the information processing method for traffic management disclosed by the invention has the beneficial effects that:
the present invention gives a navigation prompt to a vehicle (vehicle of the third route section) that is rearward and has an alternative route based on the average speed of a vehicle (vehicle on the first route section) that has not yet entered a congested section (the second route section), so that the driver of the rearward vehicle (vehicle on the third route section) has room to select another form of route by driving out from the exit.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention.
The summary of various implementations or examples of the technology described in this disclosure is not a comprehensive disclosure of the full scope or all features of the disclosed technology.
Detailed Description
To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the invention have been omitted.
The invention discloses an information processing method for traffic management, which is particularly suitable for navigating vehicles running on an expressway and facing a front congestion road section. The information processing method for traffic management includes the steps of:
acquiring the average speed of a vehicle positioned on a first road section; in this step, a mobile terminal is placed in the vehicle, the mobile terminal is integrated with a navigation system, and the data processing center obtains the speed of each vehicle traveling on the first road section by means of communication between the satellite and the mobile terminal, and calculates the average speed of all vehicles on the road section.
Determining whether an average speed of vehicles on a first road segment is within a first speed range; in this step, the first speed range is much smaller than the high speed limit speed of 120km/h, for example, the first speed range of 30-55km/h, and when the vehicle on the first road section is located in the speed range, it means that the vehicle on the first road section is much smaller than the limit speed, which means that although the road section does not constitute a congested road section, there is a possibility that a certain road section ahead of the road section is congested.
And if the average speed of the vehicles on the first road section is within the first speed range, inquiring whether a second road section in a congestion state exists in front of the first road section. The significance of this judgment lies in: whether the average speed of the vehicles in the first road section is within the first speed range or not needs to be known whether congestion occurs in the front or not.
If the second road section in the congestion state exists, sending indication information to vehicles on a third road section which is behind the first road section and has at least one outlet between the second road section and the vehicles; wherein: the indication information at least includes: location information and congestion level information for the second road segment, and location information for the exit. For example, when the vehicle traveling speed of the second link is 40km/h, the lower traveling speed may be caused by congestion of the link ahead, and thus, it is queried whether there is a congestion state in the link ahead, and when it is queried that there is a congested link ahead (the congested link is defined as the second link), the data processing center transmits information about the position of the congested link, the congestion degree, and the position of the exit ahead of the vehicle to a vehicle on a link (not referred to as a third link as well) traveling behind the first link and having an exit with the first link, for example, a mobile terminal on the vehicle may emit a prompt sound "congestion 20km ahead, high speed exit 10 km ahead".
The advantages of the above embodiment are:
the present invention gives a navigation prompt to a vehicle (vehicle of the third route section) that is rearward and has an alternative route based on the average speed of a vehicle (vehicle on the first route section) that has not yet entered a congested section (the second route section), so that the driver of the rearward vehicle (vehicle on the third route section) has room to select another form of route by driving out from the exit.
In a preferred embodiment of the present invention, on the basis of the above embodiment, when a situation that the congestion degree of the vehicle on the second road segment is greater than the preset congestion degree is encountered, the indication information further includes: and the prompt information is used for prompting the vehicles on the third route section to exit from the exit. For example, when the congestion degree of the second road segment is large, which may cause that the vehicle on the third road segment may not pass through the second road segment after passing through the first road segment and entering the second road segment, and the length of the second road segment may be increased (increase the length of the congested road segment) due to the continuous driving of the vehicle, the mobile terminal may send a prompt sound "the congestion is serious at 20km ahead, the high-speed exit is provided at 10 km ahead, and the high-speed exit is recommended to drive out the highway from the high-speed exit"
In a preferred embodiment of the present invention, based on the above embodiment, the first speed range is divided into a first speed segment and a second speed segment, the first speed segment is lower than the second speed segment, and if the average speed of the vehicles on the first road segment is within the second speed segment, the vehicle on the third road segment having at least two exits from the first road segment is prompted to exit from the exit closest to the first road segment; and if the average speed of the vehicles on the first road section is within the first speed section, prompting the vehicles on the third road section, which are at least provided with two outlets and are far away from the first road section, to drive out from the outlet which is far away from the second road section.
Preferably, the first speed segment is 30-40km/h and the second speed segment is 40-55 km/h.
Preferably, the congestion state is determined based on a traveling speed of the vehicle, and when an average speed of the vehicle is within a second speed range, the link where the vehicle is located is determined to be the second link in the congestion state.
Preferably, the second speed range is 0-15 km/h, and the average speed of the vehicle corresponding to the preset congestion degree is 5 km/h.
