Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the specific implementation cases of the present invention will be described below in conjunction with the accompanying drawings.

[0039] The invention discloses a method for evaluating the safety of setting distances of ETC indicator signs at main line toll stations based on dynamics simulation. The process is as follows: figure 1 shown.

[0040] Such as figure 2 As shown, it is a schematic diagram of the plane design scheme of a certain ETC main line toll station. The basic section 1 of the expressway has four lanes in one direction, numbered A, B, C, and D from the inside to the outside, and the traffic volume is 6000 vehicles / hour, and the design speed is 100km / h, lane width 3.75m, there are 6 toll lanes in the toll plaza, including an ETC lane 2, which is arranged on the innermost side, the distance between the ETC sign 3 and the toll booth is 500m, and the length of...

Abstract

The invention discloses an ETC (Electronic Toll Collection) indication sign setting distance safety evaluation method for a mainline toll station on the basis of dynamics simulation. The method comprises the following steps that: 1) determining the lane change process and the lane change model of a vehicle on the mainline toll station provided with the ETC indication sign, and calculating the longitudinal displacement L of the vehicle along a lane direction in the lane change process according to road parameters; 2) determining a control function for evaluating the ETC indication sign settingdistance; 3) applying Adms / Car software to construct a driver-vehicle-mainline toll station road section virtual experiment simulation platform; 4) carrying out simulation acquisition on the dynamic index of the vehicle when the vehicle carries out lane change driving according to the indication sign on the toll station road section provided with the ETC indication sign; and 5) according to the dynamic index obtained in the 4), judging whether the requirements of the control function are met or not. By use of the method, a person-vehicle-road virtual simulation experiment platform is established, and whether a distance between the existing ETC indication sign and a toll booth meets the safety requirement of the lane change process of the vehicle or not through simulation analysis.

Description

technical field [0001] The invention belongs to the research field of safety design and management of toll stations, and in particular relates to a method for evaluating the safety of setting distances of ETC indicator signs at mainline toll stations based on dynamics simulation. Background technique [0002] At present, most of the charging methods in our country are manual semi-automatic charging methods. Manual charging MTC is still the dominant mode of toll stations at present. However, with the development of technology, automatic charging ETC (Electronic Toll Collection Electronic Toll Collection System) and MTC (Manual Toll Collection, manual semi-automatic toll system) coexistence toll mode is the main toll form of expressway in our country. [0003] The difference between ETC and MTC charging methods causes two different traffic flows to interfere with each other. At the same time, due to the unreasonable setting distance of ETC lane indicators, vehicles change lane...
