Embodiment Construction

[0029] The technical solution of the present invention is: Statistically analyze and fit the upstream and downstream measured data of the automatic fixed speed measurement system device, obtain a curve model of the change law of the vehicle speed near the device, and analyze based on the curve model that the vehicle speed in the upstream of the device decreases to the speed limit value The approximate position and the position where the downstream vehicle speed returns to the speed limit value, so the specific position relative to the dangerous point in the specific setting process of the automatic fixed speed measuring device can be considered. The specific plan is as follows:

[0030] Step 1: Acquisition of upstream and downstream vehicle speed data of the automatic fixed speed measurement system device

[0031] It is necessary to select road sections that have been installed with automatic fixed speed measurement system devices to carry out on-site data collection, and set ...

Abstract

The invention relates to a setting method for an automatic fixed speed measurement system device based on a speed control effect. Firstly, vehicle speed data of different sections of an upstream and a downstream of the system device are collected on the spot; a curve model, namely a speed control effect model, of the device is obtained through statistic analysis and model simulation, wherein the curve model affects upstream and downstream vehicle speed; and an approximate position where an upstream vehicle speed of the device is reduced to a limit value and an approximate position where a downstream vehicle speed of the device is reset to the limit value are obtained according to a curve, therefore advice can be provided for a detail setting position of the system device nearby a dangerous place where overspeed is easy to happen. The method for detail setting of the automatic fixed speed measurement system device is explicit and reasonable.

Description

technical field [0001] The invention is used in the technical field of road traffic safety law enforcement, studies the speed control effect model of the automatic fixed speed measurement system device through the actual measurement data, and proposes a specific setting method for the automatic fixed speed measurement system device based on the speed control effect model, which is beneficial to the traffic police more conveniently Apply speed law enforcement technology on the road to get better law enforcement effect. Background technique [0002] Speeding is one of the important factors leading to road traffic accidents. From 2006 to 2009, the total number of road accidents in the country was 1,209,545, of which 121,029 were speeding accidents, accounting for about 10% of the total number of accidents; the total number of deaths was 312,347, of which due to The number of deaths caused by speeding was 43,394, accounting for 13.9% of the total fatalities. Traditional speed e...
