Embodiment Construction

[0017] The turn in the following embodiments refers to a left turn.

[0018] see figure 1 As shown, it is a traffic control method based on ground induction coils and variable lanes according to an embodiment of the present invention, including the following steps:

[0019] S1: Set a variable lane backwards from the stop line of the straight lane on a straight lane directly adjacent to the turning lane.

[0020] S2: Set a variable lane stop line at the entry position of the straight vehicle on the through lane with the variable lane; set a variable lane near the variable lane stop line on the turn-only lane The entrance of the variable lane; the ground induction coil is arranged at the stop line of the variable lane, the entrance of the variable lane and the departure position of the variable lane.

[0021] S3: Avoid the entrance of the variable lane on the turn-only lane and set a no-parking area with at least one parking space length adjacent to the entrance near the inter...

Abstract

The invention relates to a traffic control method and system based on a sense coil and a variable lane. Turning on and turning off of a turning green lamp or a straight running green lamp in a main indication lamp are accurately controlled by tracking leaving conditions of vehicles moving into the variable lane before change, namely the green lamp time required by the vehicles moving into the variable lane before a function of the variable lane is changed to leave safely is guaranteed, the vehicles on the variable lane are cleared away timely, and normal passage of vehicles in the following signal period cannot be disturbed. Further, the indication condition of the main indication lamp can be changed at the first time after the vehicles moving into the variable lane before the function of the variable lane changes leave safely, for example, the straight running green lamp is converted into the turning green lamp. Accurate control of the main indication lamp is achieved, and road junction passage capability is improved in a maximizing mode.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a traffic control method and control system based on ground induction coils and variable lanes. Background technique [0002] With the increase of motor vehicles, the existing road resources are becoming more and more tense, and congestion often occurs, which greatly affects the travel efficiency of residents. Therefore, how to make full use of existing road resources through reasonable channelization and control has become the focus and difficulty in the field of traffic control. [0003] Chinese patent document CN102938204A discloses a control method for changing the steering function of a variable guiding lane at an urban intersection, which specifically includes: detection of traffic flow occupancy; discrimination of changing of the steering function of the variable guiding lane; moment of turning change of the variable guiding lane Selection; Calculation of clearing time of v...
