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

Abstract

The invention belongs to the technical field of road traffic and discloses a system and method for correcting a congestion degree display result of an electronic map. The system comprises an information collection unit and a decision-making unit, wherein the information acquisition unit is used for acquiring GPS information of a smart phone; the decision-making unit is used for analyzing and judging the acquired GPS information of the smart phone, and determining the vehicle type, the congestion degrees of a social lane and a bus lane and the corrected overall congestion degree of the road; according to the system, buses and social vehicles can be accurately distinguished based on the acquired GPS information of the smart phones of drivers and passengers; the congestion degrees of the social lane and the bus lane are respectively calculated by utilizing the information acquired by the electronic map; and finally, the corrected overall congestion degree of the road is obtained by usinga weighted sum mode. According to the method, the method is simple, the overall congestion degree of the road can be accurately calculated, the drivers can be reminded to take appropriate evasion measures, and the traffic safety of the road is guaranteed.

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, ...

AI Technical Summary

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
