Embodiment

[0036]Based on the GPS positioning of the mobile terminal, when the vehicle loaded with the mobile phone does not arrive at the intersection entrance, it will be notified in advance of the traffic signal situation at the intersection ahead when it arrives, including the color of the light and the countdown countdown, and at the same time, it will provide driving speed advice for the vehicle value to make it drive in the green band as much as possible.

[0037] This kind of trunk line green wave vehicle speed guidance system based on mobile terminal GPS positioning, such as figure 1 , including a data acquisition unit, a GPS positioning unit, a data processing unit, a display unit, and a storage unit.

[0038] Data acquisition unit: By accessing the data of the urban road signal control system, the intersection signal control scheme is obtained, and the obtained intersection signal control scheme is processed by the data processing unit.

[0039] GPS positioning unit: Based on...

Abstract

The invention provides a main line green wave speed induction system and a method based on mobile terminal GPS positioning. The system comprises a data acquisition unit, a GPS positioning unit, a data processing unit, and a display unit, and the data processing unit calculates the distance l from a vehicle to a downstream intersection via the real-time driving position of the vehicle and the time t=l / v for driving to the downstream intersection at the current speed, calculates display of each turning signal lamp of an entrance driveway and countdown conditions of the vehicle arriving time according to the driving time t for reaching the downstream intersection of the vehicle, and gives a speed suggested value or interval. According to the system and the method, the speed suggested value is pushed to the vehicle according to the vehicle positioning condition, the induction is more effective, targeted, and flexible, vehicle positioning data is acquired via a mobile terminal GPS so that the installation of a fixed vehicle detection device is not needed, and related information is displayed via a mobile terminal so that the installation of a fixed information publishing device at a roadside is not needed.

Description

technical field [0001] The invention relates to a system and method for inducing a green wave vehicle speed on a trunk line based on the GPS positioning of a mobile terminal. Background technique [0002] In the urban road network, the arterial collaborative control method is often adopted to improve the traffic operation efficiency of the arterial road, reduce the number of vehicle parking, and ensure the smooth passage of the arterial road traffic flow. Green wave speed warning signs are erected on some roads that implement coordinated control of trunk lines to provide drivers with suggested driving speed values ​​that can enter the green wave. However, affected by various factors such as intersection spacing, entrances and exits along the road, non-motor vehicles and pedestrian interference, it is difficult for driving vehicles to stay within the green wave zone of the main road at the design speed of the traffic engineer, which means that it is possible to drive in the g...
