Abstract

The invention discloses an induction type give-way control system for primary and secondary road junctions under poor sight distance conditions. The induction type give-way control system comprises magnetic induction detection coils, a data transmission device, a control system center and crystal diode signs. The magnetic induction detection coils are used for detecting the current speeds, vehicle lengths and moments of vehicles at all entrance lanes. The data transmission device is used for transmitting data to the control system center in a wireless broadcasting mode and sending instructions generated by the control system center to the crystal diode signs. The control system center is used for calculating the time when the vehicles at the primary and secondary road junctions reach the points where conflicts may happen and generating corresponding instructions. The crystal diode signs are used for prompting the vehicles going to enter the road junctions along secondary roads to give way or pass through according to the instructions sent by the control system center. The invention further provides an induction type give-way control method for primary and secondary road junctions under poor sight distance conditions. Induction type give-way signs are arranged at the primary and secondary road junctions, driving behaviors of drivers of vehicles on the secondary roads are helped and induced, traffic conflicts of the vehicles on the primary and secondary road junctions are reduced, and driving safety at no-signaled road junctions is improved.

Description

technical field [0001] The invention relates to the technical field of traffic management at unsignalized intersections, in particular to an inductive yield control system and method for primary and secondary intersections under the condition of poor sight distance. Background technique [0002] Level intersections are the nodes of the urban road network. Although they occupy a small part of the entire urban road network in space, traffic accidents at level intersections account for a large proportion of the entire urban road network accidents. According to statistics, 55% of American urban vehicle traffic accidents occur at intersections, and 23% of American urban fatal traffic accidents occur at intersections; about 24% of traffic accidents in France occur at intersections; about 33% of traffic accidents in Britain Accidents occur at intersections; about 30% of traffic accidents in Chinese cities occur at level intersections, and about 80% of congestion also occurs at inte...
