Road section pedestrian traffic signal control system based on pedestrian crossing clearance time

Abstract

The invention discloses a road section pedestrian traffic signal control system based on pedestrian crossing clearance time. The road section pedestrian traffic signal control system based on the pedestrian crossing clearance time comprises a pedestrian data acquisition and recording unit, a pedestrian crossing clearance time computing unit and a signal implementation and feedback unit, and is applicable to pedestrian signal timing designs of thick crowd crossing districts and intersections with exclusive pedestrian phases. The road section pedestrian traffic signal control system based on the pedestrian crossing clearance time comprehensively takes time loss and pedestrian crossing traffic capacity decline due to mutual disturbance of stream of people of opposite directions during thick crowd crossing into consideration, overcomes the defects that the pedestrian speed is used as a constant and the pedestrian crossing capacity is unchanged in a traditional pedestrian traffic signal control, so that the timing result is more accurate and practical. Only the pedestrian flow and the pedestrian speed of the pedestrian crossing are needed to be measured and computed, so that the computation is concise.

Description

Technical field [0001] The invention belongs to the field of traffic engineering design, and specifically relates to a pedestrian traffic signal control system, particularly a road section pedestrian crossing traffic signal control system and a setting method. Background technique [0002] There is a high demand for pedestrian crossing in the city. The reasonable setting of pedestrian crossing facilities is a necessary prerequisite to meet pedestrian crossing needs, an important technical means to ensure pedestrian crossing safety, and an in-depth practice of the "people-oriented" traffic engineering design concept. [0003] Pedestrian signal control is an important part of the installation of pedestrian crossing facilities. Pedestrian signal control is generally divided into two types: road section pedestrian traffic signal control and intersection pedestrian traffic signal control. Since the main function of the intersection is to satisfy the traffic of motor vehicles, the pedes...

AI Technical Summary

Problems solved by technology

However, for areas with a large number of pedestrian crossing needs in a certain period of time, such as commercial districts, primary and secondary schools, etc., the target pedestrian flow conflict is serious. Reduced to 0, in this case, the basic estimated time is less than the actual time required for pedestrians to cross the street, so that pedestrians cross the road at red light time, which not only creates potential safety hazards, but also reduces the traffic efficiency of the road section
