Problems solved by technology

[0003] There are many reasons for traffic congestion. One of the most important reasons is the delay in the planning of parking lots in the city. The lack of parking lots leads to nowhere for vehicles to park after arriving at the destination. They can only go around the destination to find parking spaces. , we call this phenomenon "ineffective driving". "Ineffective driving" not only causes the driver to waste time and increase costs, but also increases the traffic flow in the city and aggravates urban congestion, thus reducing "ineffective driving" , reasonable planning of urban parking spaces has become one of the urgent tasks facing the city management department

Embodiment 1

[0042] Such as figure 1 As shown, a vehicle non-effective driving track identification method includes the following steps:

[0043] S1. Obtain the passing data in the specified area and within the specified time period from the checkpoint big data platform;

[0044] Such as figure 2 As shown, the specific steps for obtaining data in step S1 are as follows:

[0045] S11. Reading data of passing vehicles at the bayonet. Obtain the checkpoint passing data in the specified area and within the specified time period from the checkpoint big data platform. The checkpoint big data platform includes the license plate number of the vehicle in the designated area, the model, the time point when driving in the designated area, The latitude and longitude of the corresponding position at each time point, the license plate number, the vehicle type, each time point, and the latitude and longitude of the corresponding position at each time point are taken as the objects to be analyzed.

...

Embodiment 2

[0067] A method for planning urban road facilities, including all the steps in Embodiment 1, the bayonet in the above steps refers to a camera that captures license plates and vehicle violations. When the cameras are relatively dense, the value of T in step S12 is 10min; when the density of cameras is general, the value of T in step S12 is 20min; The value of T in is 30min. In this way, more effective vehicle trajectory lines can be obtained.

[0068] Then it also includes the following steps: judging whether the driving trajectory is a closed curve; if the non-effective driving trajectory is a closed curve, then establishing a parking lot facility in this closed area; if the non-effective driving trajectory is a non-closed curve, and there is an optimal driving road , add road signs and other facilities to guide vehicles or increase road construction planning.

Abstract

The invention discloses a vehicle non-effective traveling track recognition method and urban road facility planning method. The vehicle non-effective traveling track recognition method includes the steps of S1. obtaining vehicle passing data in a specified area and within a specified time period from a checkpoint big data platform; S2. using a corresponding checkpoint position when a vehicle enters the specified area as a starting point of a track, and using a corresponding checkpoint position when the vehicle travels out of the specified area as an end point of the track, thereby obtaining a vehicle traveling track distribution diagram; S3. adopting a vehicle track hierarchical clustering analysis method based on buffer area similarity measurement to analyze a vehicle traveling track, thereby forming a track group; and S4. comparing the track group with an optimal path based on GIS road network data, thereby obtaining a vehicle non-effective traveling track. The advantage of the method is that support is provided for urban road infrastructure planning judgment.

Description

technical field [0001] The invention relates to the fields of urban road infrastructure planning and intelligent transportation, in particular to a method for identifying non-effective driving tracks of vehicles and a method for planning urban road facilities. Background technique [0002] With the rapid development of social economy, the acceleration of urbanization, the continuous improvement of people's living standards, and the rapid growth of urban traffic demand, traffic problems have become a major problem that plagues urban development. The time wasted and operating costs it brings Problems such as rising traffic, traffic accidents, air pollution, and noise pollution have made traffic congestion a "bottleneck" that restricts urban economic and social development. How to avoid and reduce the impact of traffic congestion and maintain the high-speed, safe and comfortable characteristics of road traffic has It has become an urgent problem to be solved by the transportati...
