Embodiment 1

[0052] The floating car queuing length calculation toll booth and the traffic light real-time road condition information technology include the following steps:

[0053] A: Externally provide toll stations, traffic lights, and map data based on monthly map calculations, write them into redis and couchbase, and write city information into redis;

[0054] B: The principle of making toll stations, the length of the link is limited to 200 meters: other instructions, if the current link length is less than 200 meters, but the next LINK is added to exceed 200 meters, add the next LINK, if the topology length is less than 200 meters, reverse the topology to The first sub-confluence point will not be interrupted to continue the topology. When the second sub-confluence point is encountered in the link topology, it will be interrupted, and the manual maintenance function of the toll station is supported;

[0055] C: The principle of making traffic lights, the length of the link is limit...

[0071] A: Externally provide toll stations, traffic lights, and map data based on monthly map calculations, write them into redis and couchbase, and write city information into redis;

[0072] B: The principle of making toll stations, the length of the link is limited to 200 meters: other instructions, if the current link length is less than 200 meters, but the next LINK is added to exceed 200 meters, add the next LINK, if the topology length is less than 200 meters, reverse the topology to The first sub-confluence point will not be interrupted to continue the topology. When the second sub-confluence point is encountered in the link topology, it will be interrupted, and the manual maintenance function of the toll station is supported;

[0073] C: The principle of making traffic lights, the length of the link is limit...

Embodiment 3

[0088] The floating car queuing length calculation toll booth and the traffic light real-time road condition information technology include the following steps:

[0089]A: Externally provide toll stations, traffic lights, and map data based on monthly map calculations, write them into redis and couchbase, and write city information into redis;

[0090] B: The principle of making toll stations, the length of the link is limited to 200 meters: other instructions, if the current link length is less than 200 meters, but the next LINK is added to exceed 200 meters, add the next LINK, if the topology length is less than 200 meters, reverse the topology to The first sub-confluence point will not be interrupted to continue the topology. When the second sub-confluence point is encountered in the link topology, it will be interrupted, and the manual maintenance function of the toll station is supported;

Abstract

The invention discloses a technology for calculating toll station and traffic light real-time road condition information based on floating car queuing length. The method comprises the steps that A toll station, traffic light and map data which are provided by the outside and calculated based on a monthly version map are written into the redis and couchbase, and city information is written into the redis; B according to the toll station manufacturing principle, the link length is limited to be 200 meters, if the current link length is smaller than 200 meters, but the added next LINK exceeds 200 meters, the next LINK is added, if the topology length is smaller than 200 meters, reverse topology is conducted to a first sub-confluence point without interruption, topology continues, and when a second sub-confluence point is encountered in the link topology, interruption is conducted. The method has the advantage of more accurately reflecting the congestion, slow or unblocked state of the road in the toll station and traffic light range, and solves the problem that the toll station and traffic light scene road condition state calculation is not very accurate due to excessive dependence on the speed.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to the technology for calculating the queuing length of floating vehicles toll stations and the real-time road condition information technology of traffic lights. Background technique [0002] Real-time traffic conditions is a concept put forward in view of the unimpeded traffic congestion in today's cities. Currently, real-time traffic conditions are a mature vehicle-mounted intelligent traffic navigation technology. Real-time traffic conditions can reflect the traffic conditions in the region in real time and guide the best and fastest driving Routes, improving the efficiency of road and vehicle use, for car owners, the biggest headache may not be the fuel costs that only rise but not fall, nor are all kinds of cumbersome maintenance, but living in congested roads every day, living a life Life with a car is slower than without a car, and mastering real-time road...
