Embodiment Construction

[0016] The method and system for applying ETC to collect traffic flow in expressway service areas in the present invention are mainly applicable to the collection of traffic flow in expressway service areas.

[0017] refer to figure 1 , figure 2 , the method of applying ETC to expressway service area to collect traffic flow in the present invention will be described in detail below.

[0018] Such as figure 1 As shown, a method of applying ETC to expressway service area to collect traffic flow in this embodiment includes the following steps:

[0019] The first step is to install two or more ETC antennas on the on-ramp and off-ramp of the expressway service area, interact with the vehicle terminal, and obtain the original traffic flow data, so as to ensure that the on-ramp and exit of the diversified expressway service area In the form of ramps, it can also effectively guarantee the collection rate of vehicle terminals (including OBU and CPC);

[0020] The second step is to...

Abstract

The invention provides a method and system for applying ETC (Electronic Toll Collection) to a highway service area to collect traffic flow, and the method comprises the following steps: 1, installing two or more than two ETC antennas at an entrance ramp and an exit ramp of the highway service area, and carrying out the interaction with a vehicle-mounted terminal; 2, deploying an edge calculation module in the expressway service area, and controlling a plurality of antennas of an entrance ramp and an exit ramp of the expressway service area; 3, designing an algorithm of an edge calculation module, and interacting two or more antennas on the same ramp with the vehicle-mounted terminal in a polling starting mode; 4, the antennas of the entrance ramp and the exit ramp of the expressway service area collect vehicle data, according to the time sequence of collection of the vehicle data, fitting is carried out to obtain vehicle driving path information, and the vehicle driving path information is uploaded to a service area data system.The method for applying ETC to the expressway service area to collect the traffic flow is high in collection success rate and high in speed. The cost is low.

Description

technical field [0001] The invention relates to a method for collecting traffic flow, in particular to a method for applying ETC to a highway service area to collect traffic flow. Background technique [0002] The expressway service area is an important operation and service node of the expressway. At present, vehicle information collection in expressway service areas is mainly completed by bayonet cameras, and some large service areas try to enhance the dimension and quality of supplementary data through equipment such as radar and radar vision systems (that is, radar and video fusion systems). However, the existing technical solutions have their own limitations, making it difficult for the accuracy, integrity and stability of the collected vehicle information to reach the level of effective business analysis in expressway service areas. The types, characteristics and defects of vehicle sensing technologies in existing application and service areas are summarized as follow...
