Description

Technical Field

[0001] The present invention relates to the technical field of urban traffic facilities, and in particular to a pedestrian and vehicle overpass device at an intersection and an implementation method thereof, aiming to solve the problems of traffic congestion and frequent accidents at intersections. Background Art

[0002] (1) Problems with existing technologies

[0003] With the continued rise in motor vehicle ownership and the intensification of population mobility associated with urbanization, urban traffic congestion is becoming increasingly severe, with congestion at intersections being a particular issue. During rush hour, vehicles often have to wait for two or three green lights before passing through an intersection, severely impacting travel efficiency.

[0004] Currently, traffic control at intersections primarily relies on traffic lights. However, this method has significant drawbacks. Failure to strictly follow traffic light instructions by vehicles or pedestrians can easily lead to collisions. Because the collisions occur from intersecting directions, the consequences are often severe, making intersections a high-incidence area for traffic accidents.

[0005] (2) Limitations of existing improvement measures

[0006] While my country has made significant progress in road construction and traffic management, with increasingly efficient and effective vehicle and pedestrian management at intersections and the gradual improvement of supporting facilities, putting it at the forefront of the world to a certain extent, urban traffic congestion remains widespread due to its large population and rapid urban development. This problem has become a global bottleneck. Despite the continuous efforts of all parties, little progress has been made, and the "sluggish" urban traffic situation remains largely unresolved.

[0007] (3) Root cause analysis

[0008] In reality, the inherent capacity of urban roads is sufficient to meet traffic demand, ignoring the impact of traffic lights at intersections. The crux of urban road congestion lies at intersections. Crossing traffic and pedestrians share the same road, controlled by traffic lights, requiring vehicles and pedestrians to alternate. This highly rhythmic traffic flow makes it difficult for both vehicles and pedestrians to strictly adhere to traffic regulations, making errors prone to occur and leading to traffic accidents. Therefore, solving the traffic problem at intersections has become a pressing issue for many. Summary of the Invention

[0009] The purpose of the present invention is to provide a solution that can effectively solve the global problem of traffic congestion. By providing a pedestrian and vehicle overpass device at an intersection and its implementation method, traffic light control can be eliminated, the vehicle travel speed can be greatly improved, and the incidence of traffic accidents at intersections can be significantly reduced.

[0010] To achieve the above objectives, the present invention provides the following technical solutions:

[0011] A pedestrian and vehicle overpass device at an intersection, comprising a main structure, an emergency design structure, a safety protection structure, and a signal auxiliary structure;

[0012] The main structure is a pedestrian-vehicle overpass structure, which is no less than four meters above the ground. The pedestrian-vehicle overpass structure consists of a central plane bridge frame and upper and lower bridge components on both sides, and the entire structure vertically spans the ground lane and sidewalk; the upper and lower bridge components on both sides are either upper and lower inclined approach bridges or mechanical lifting mechanisms;

[0013] The emergency design structure includes a middle plane bridge frame constituting a pedestrian and vehicle overpass, and at least a portion of the upper and lower bridge components on both sides is manually or electrically movable;

[0014] The safety protection structure includes multiple elastic safety baffles arranged on the inclined surface of the vehicle boarding inclined approach bridge;

[0015] The signal auxiliary structure includes green light buttons set at both ends of the ground sidewalk. The green light buttons are used by wheelchairs, disabled people or vehicles or people who cannot cross the street normally on the bridge. The existing traffic light signals that were originally blocked by the overpass are set to the bridge or a clearly visible position.

[0016] Furthermore, the mechanical lifting mechanism actively lifts the vehicle to the upper bridge deck or lowers the vehicle from the upper bridge deck to the ground. The power required for its operation comes from the vehicle itself, and the sidewalk part adopts an inclined approach bridge method.

[0017] A method for implementing a pedestrian-vehicle overpass device at an intersection, the method comprising the following traffic rules:

[0018] Vehicle traffic rules:

[0019] Vehicles traveling straight or turning left on the lane where the pedestrian-vehicle overpass is located are required to cross the street on the bridge. Vehicles turning left are required to make a U-turn into the opposite lane after crossing the bridge, and then turn right.

[0020] Vehicles turning right on the lane where the pedestrian-vehicle overpass is located do not need to go up the overpass and can directly enter the right-turn lane to wait for the turn;

[0021] Vehicles turning right on the ground lane can turn right directly; vehicles turning left need to cross the street or turn around first, then go forward and turn right;

[0022] Pedestrian traffic rules: Pedestrians must cross the street via the sidewalk on the bridge;

[0023] Passage rules for special groups: Vehicles or people in wheelchairs, people with disabilities, or those unable to cross the street on the bridge can pass quickly and safely after pressing the green light buttons at both ends of the ground sidewalk to request to cross the street; the green light will go out at a fixed time, or when vehicles stopped at the light are sure that the person or vehicle crossing the street has passed and there are no people or vehicles passing on the sidewalk, they can ignore the green light and continue to pass, thereby saving time.

[0024] Furthermore, the existing traffic light system will be retained for use in special circumstances.

[0025] The pedestrian and vehicle overpass device at an intersection and the implementation method thereof of the present invention have the following beneficial effects:

[0026] 1. Improve traffic efficiency: The implementation of this plan will greatly increase the traffic speed of urban vehicles and pedestrians, shorten the dynamic road occupation time of vehicles, improve road utilization, save driving time and fuel consumption when waiting for lights or following vehicles.

[0027] 2. Alleviate traffic congestion: It reduces the probability of vertical collisions between vehicles at intersections, greatly alleviating traffic congestion, especially during rush hour or holiday traffic peak hours, the congestion situation will be greatly improved.

[0028] 3. Improve the mood of traffic participants: Traffic participants are in a happier mood, which reduces road rage. As vehicles pass through smoothly, drivers will also feel more comfortable.

[0029] 4. Reduce the accident rate: Drivers no longer need to stare at traffic lights and have enough energy to pay attention to the status of other people and cars, which helps reduce the occurrence of traffic accidents such as scratches and collisions. BRIEF DESCRIPTION OF THE DRAWINGS
