Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-2 As shown, a method for calculating the passing time of vehicles at signal light intersections includes the following steps:

[0022] A. Utilize the current dynamic GPS data of the target vehicle 1 to calculate the current speed v of the target vehicle 1;

[0023] B. If v0 , it is considered that the target vehicle 1 enters the waiting queue and is in the state of waiting to pass; if v>v 0 , then the target vehicle 1 is considered to be in a normal driving state; where, v 0 To preset the speed, set v 0 12km / s;

[0024] C, utilize the GPS data collection device to obtain the current dynamic GPS data of the target vehicle 1 in real time, combine the static GPS data of the signal lamp 3 to be passed, convert the current dynamic GPS data of the target vehicle 1 into the distance D of the crosswalk 2 opposite the signal lamp 3;

[0025] D. Let the aver...

Abstract

The invention discloses a method for calculating time for a vehicle to pass through a signal lamp intersection. The method comprises the following steps of: calculating the current speed v of a target vehicle by utilizing current dynamic GPS (Global Position System) data of the target vehicle; judging the current state of the target vehicle; converting the current dynamic GPS data of the target vehicle into the distance D of a pedestrian crosswalk opposite to the signal lamp; calculating the current sequencing in a waiting queue of the target vehicle; and calculating the time t for the current target vehicle to pass through the signal lamp. Because a GPS technology is sufficiently utilized and a complete calculation formula is provided, the time for the target vehicle to pass through the signal lamp intersection can be calculated accurately in advance. Because the time for the vehicle to pass through the signal lamp intersection can be calculated accurately in advance, the time lengthof the signal lamp at the intersection can be conveniently optimized and controlled by a management department.

Description

technical field [0001] The invention relates to a traffic flow management method, in particular to a method for calculating the passing time of vehicles at signal light intersections. Background technique [0002] With economic development and technological progress, transportation has become an important aspect of economic life, and it plays an increasingly important role in ensuring the normal operation of the social and economic system. Save time and improve the work process. However, with the rapid development of transportation, it has also brought many disadvantages, especially the ground automobile transportation, whether it is a developed country or a developing country, there are problems such as traffic congestion and road blockage. [0003] City signal lights play an important role in managing and guiding traffic in cities. However, there are too many vehicles, especially during rush hour, and signal lights have become a very important reason for traffic congestio...
