System and method for correcting display results of electronic map congestion degree

Abstract

The invention belongs to the technical field of highway traffic, and discloses a system and method for correcting the display result of the congestion degree of an electronic map, including: an information collection unit and a decision-making unit; wherein, the information collection unit is used to obtain GPS information of a smart phone; decision-making The unit is used to analyze and judge the GPS information obtained from the smartphone, and determine the vehicle type, the congestion degree of social lanes and bus lanes, and the corrected overall road congestion degree; the system is based on the obtained driver and passenger intelligence. The GPS information of the mobile phone can accurately distinguish between buses and social vehicles, and use the information obtained from the electronic map to calculate the congestion levels of social lanes and bus lanes, and finally use the weighted summation method to obtain the corrected overall road congestion level. The method is simple, can accurately calculate the overall road congestion degree, and is beneficial to remind drivers to take appropriate avoidance measures to ensure road traffic safety.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a system and a method for correcting the display result of the congestion degree of an electronic map. Background technique [0002] Nowadays, the traffic road network is becoming more and more developed, and the emergence of electronic maps provides convenience for people's daily travel, and also provides support for the efficient and accurate operation of the traffic management system. However, with the increase of road types and the emergence of different traffic lines, the accuracy of the description of electronic maps needs to be improved. [0003] For example, on roads with bus-only lines, buses and social vehicles go their separate ways. Existing electronic maps cannot distinguish the congestion levels of social lanes and bus lanes, so they can only simply calculate the congestion level of the entire road. This congestion level is actually not accurate. In this way, ...

Problems solved by technology

Existing electronic maps cannot distinguish the congestion levels of social lanes and bus lanes, so they can only simply calculate the congestion level of the entire road. This congestion level is actually not accurate. In this way, the congestion levels of the two lines can be simply unified The calculation does not take into account the congestion levels of different lines. For example, when the social lanes are congested but the bus lanes are smooth, there will be a certain error in the congestion level of the electronic map, that is, the actual congestion level of the social lanes is higher than the congestion calculated by the electronic map. The actual congestion level of the bus lane is higher than the congestion level calculated by the electronic map
