Embodiment Construction

[0053] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0054] Such as figure 1 Shown, the blocking suppression method implementation step of the present invention is:

[0055] Step 1. Set the initial parameters according to the vehicle, including the sensitivity parameter α i , the maximum velocity parameter v max , expected headway spacing η i , the adjustment parameter of the expected vehicle speed and data sampling time interval T;

[0056] Step 2. Determine the feedback coefficient k of the feedback control signal according to the non-blocking feedback condition of the road traffic system i , stored in the microcontroller;

[0057] Step 3. The speed information measured by the on-board speedometer is transmitted to the single-chip microcomputer, and the single-chip microcomputer determines the feedback coefficient according to the designed feedback control signal formula [formula (2)] and the ...

Abstract

The invention discloses a jam prohibiting method for a city road traffic system, advancing a jam signal control technique, transmitting front vehicle speed signal and local vehicle speed signal measured by a vehicle-carried speed measurer to a MCU, determining feedback coefficients by the MCU according to the designed feedback control signal and jam-free conditions, calculating acceleration deceleration prompting information and displaying the prompting information on a display unit, and as seeing the prompting information, a driver will properly adjust the vehicle speed, thus improving responding sensitivity of the driver so as to avoid the traffic jam. And the control technique has characters of simple structure, low cost and easy to implement, able to improve driving safety and comfortableness and making full use of road traffic capacity.

Description

technical field [0001] The invention relates to a blocking suppression method of an urban road traffic system, more specifically relates to a blocking signal control technology of an urban road traffic system, and belongs to the technical field of traffic signal control. Background technique [0002] With the development of society and economy, the number of urban motor vehicles has increased rapidly, resulting in increasing urban traffic congestion or congestion, which seriously hinders the process of urban modernization. In order to fundamentally solve the problem of urban traffic congestion, developed countries have carried out research on urban traffic control since the 1960s. area. However, the problem of urban road traffic control is quite complicated, and many results are not perfect. In particular, people seldom discuss how to rationally guide the congested traffic flow on the road according to the formation mechanism of traffic jams, so as to alleviate or prevent t...
