Embodiment 1

[0056] In this embodiment, a control scheme without pedestrian secondary crossing induction is provided, which is used in a street crossing passage provided with a safety island. The street crossing passage includes a first passage 1 and a second passage 2. In the first passage 1 A safety island 3 is arranged between the second passage 2, a first signal light 11 is arranged on the road side of the first passage 1, a second signal light 21 is arranged on the road side of the second passage 2, and the safety island 3 A third signal light 31 is provided facing the first passage 1, and a fourth signal light 32 is provided on the safety island 3 facing the second passage 2. In this embodiment, the control scheme for secondary crossing induction for pedestrians is not provided, and the pedestrian crossing Pedestrians in the channel do not stay on the safety island, but pass through the safety island to reach the opposite side of the road, then the inductive pedestrian crossing signal...

Embodiment 2

[0080] In this embodiment, a second pedestrian crossing induction control scheme is provided. The street crossing passage in this scheme is the same as that in Embodiment 1, but pedestrians can stay at the safety island and pass through the safety island twice. Pedestrian safety island is a pedestrian crossing method that divides the pedestrian crossing into two parts and makes pedestrians cross the road in two phases. This method is suitable for urban roads with wide sidewalks and wide central dividers.

[0081] On the basis of the above-mentioned embodiment 1, after setting the green light remaining time of the third signal light as the green light extension time, it also includes:

[0082] First, calculate the green light extension time of the second signal light, the green light extension time of the second signal light is the green light extension time of the third signal light plus the time for pedestrians to pass through the second channel;

[0083] Then, calculate the...

Embodiment 3

[0093]In this embodiment, an inductive pedestrian crossing signal control system is provided, which is used in a street crossing passage provided with a safety island, and the street crossing passage includes a first passage and a second passage, between the first passage and the second passage A safety island is provided, a first signal light is provided on the roadside of the first passage, a second signal light is provided on the roadside of the second passage, and a third signal light is provided on the safety island facing the first passage, so The safety island is provided with a fourth signal light facing the second channel, and the structural block diagram of the system is as follows Figure 4 shown, including:

[0094] The green light time preset unit 01 is used to set the green light time of the first, second, third, and fourth signal lights as the green light preset time when the first, second, third, and fourth signal lights turn green;

[0095] Pedestrian judging...

Abstract

The invention provides an induction type pedestrian street-crossing signal control method. According to the induction type pedestrian street-crossing signal control method, green light illumination prolonging time is obtained according the speed of pedestrians; current green light illumination remaining time is calculated according to the entering time of current pedestrians; green light illumination prolonging time and current green light illumination remaining time are calculated when pedestrians enter a street-crossing channel; and if the green light illumination prolonging time is larger than the current green light illumination remaining time, the green light illumination remaining time of a green light at an safety island corresponding to the channel which the pedestrians enter is set as the green light illumination prolonging time. With the induction type pedestrian street-crossing signal control method adopted, the problem that the pedestrians cannot normally pass through an intersection can be solved. The prolonging time is calculated according to the time when the pedestrians enter the channel, and the remaining time of the green light is prolonged according to the prolonging time, and therefore, the pedestrian who enter the intersection can normally pass through the intersection, and the safety of the pedestrians in street-crossing can be improved.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to an inductive pedestrian crossing signal control method and system. Background technique [0002] With the development of urban traffic, the urban road network is becoming more and more complex, and there are more and more intersections. When the section width of the intersection is large, the time for pedestrians to cross the intersection is sometimes relatively tight, which cannot guarantee that pedestrians can pass the intersection safely at normal speeds, because the effective green light time of crossing signal lights at intersections often only considers the time for pedestrians to cross the street. The minimum green light time, this minimum time does not consider the needs of special groups of people (such as the elderly, children, etc.), and if the pedestrian green light time is about to end, if there are still pedestrians on the zebra crossing who have not passed the inters...
