Embodiment approach 1

[0177] Embodiment 1: If the first special service convoy has the position information of the tail car, it is judged based on the position information of the tail car. When the first special service convoy meets the following two conditions at the same time, the traffic signal at the intersection resumes autonomous control: ① 5 seconds after the tail vehicle passes the intersection; ② the tail vehicle is more than 50m away from the intersection after the tail vehicle passes the intersection.

Embodiment approach 2

[0178] Embodiment 2: If there is no position information of the tail vehicle in the first special service convoy, it is judged based on the position information of the head vehicle. When the first special service convoy meets the following two conditions at the same time, the traffic signal at the intersection resumes autonomous control: ①After the leading vehicle passes the intersection (5s+length of the fleet / average speed); ②After the leading vehicle is more than (50m+length of the fleet) from the intersection.

[0179] In addition, a special case needs to be considered: if the current driving segment is the last segment in the special service route of the first special service convoy, the time when the first special service convoy passes through the downstream intersection of the current driving segment reaches the third time threshold or the first After the distance of a special service convoy passing through the downstream intersection of the current traveling section rea...

Abstract

The invention discloses a service control method and device. The method comprises the following steps: acquiring location information of a first secret service vehicle fleet, determining the current traveling road section of the first secret service vehicle fleet as well as distance and time to a first downstream crossing from the first secret service vehicle fleet according to the location information of the first secret service vehicle fleet, wherein the first downstream crossing is any one of downstream crossings of the current traveling road section on a secret service route, determining aresident crossing set according to the distance and time to the first downstream crossing from the first secret service vehicle fleet as well as queue clearance time of the first downstream crossing,and sending a resident instruction of the first secret service vehicle fleet to a traffic signal machine of each resident crossing in the resident crossing set. The technical scheme of the inventionsolves the problems that a service control scheme has high requirements on guard personnel in the prior art and crossing resident control timeliness is poor.

Description

technical field [0001] The embodiments of the present invention relate to the field of intelligent traffic control, in particular to a method and device for duty control. Background technique [0002] With the rapid development of our country's economy and the increasing number of foreign exchanges, there are more and more opportunities for major cities to hold large-scale international conferences and major events. Due to the fixed activity time, it is often the case that multiple special service convoys arrive at the same destination at the same time. How to ensure the efficient passage of multiple special service convoys, avoid conflicts to the greatest extent, and reduce the impact on normal traffic is the secret mission command and dispatch office. the goal that is pursued. [0003] The existing command and dispatch of special missions is mainly based on the professional technicians who are familiar with the signal light phase configuration to formulate the green wave ...
