The edge cloud device can set a reservable time period, and travel vehicles can make reservations for travel within the reservable time period. Therefore, the edge cloud device can count the travel information of all travel vehicles in the green wave management area under the jurisdiction of the corresponding time period. .
步骤12：根据所述出行信息，确定所述出行车辆的出行路线上的所有交叉口以及对应的交叉口信息；Step 12: Based on the travel information, determine all intersections on the travel route of the travel vehicle and the corresponding intersection information;
本发明实施例中，根据出行车辆上报的出行信息，可以得到出行车辆的基本参数，以及出行车辆的出行路线等，从而可以确定该出行路线对应的绿波管理区域内的所有交叉口以及各个交叉口对应的交叉口信息。可选的，交叉口信息可以包括交叉口渠化信息，还可以包括出行车辆上报的预约信息(即出行信息)形成的交叉口的通行量等，以及高峰小时、东西进口道的直行车大车率、南北进口道的直行车大车率、最高15分钟流率换算的交叉口进口道小时交通量等等。In the embodiment of the present invention, based on the travel information reported by the travel vehicle, the basic parameters of the travel vehicle and the travel route of the travel vehicle can be obtained, so that all intersections and each intersection in the green wave management area corresponding to the travel route can be determined.

所谓定时控制，即定时式联动控制(fixed time coordinated control)，是指根据预先存储在控制中心或信号机内的程序，选择各路口的配时，相互协调相邻路口信号的控制方式，定时式联动控制信号控制系统的基本参数包括：周期时长、绿信比、时差等，定时式联动控制的特点是：相位差等于零或者绿信比相等。The so-called timing control, that is, fixed time coordinated control, refers to a control method that selects the timing of each intersection and coordinates the signals at adjacent intersections based on a program pre-stored in the control center or signal machine. The basic parameters of the linkage control signal control system include: cycle length, green signal ratio, time difference, etc. The characteristics of the timing linkage control are: the phase difference is equal to zero or the green signal ratio is equal.
可选的，还可以确定出各交叉口的信号相位信息，即信号相位方案，所谓信号相位，即在一个信号周期内，一股或几股车流在任何时刻都获得完全相同的信号灯色显示，那么就把它们获得不同灯色(绿灯、黄灯、全红)的连续时序称作一个信号相位。通常，相位的设计形式有以下两种：一种是对称流向放行的相位设计形式(简称对称流向放行相位形式，又细分为左转相位设计、右转相位设计、行人和非机动车相位设计、东西相位设计、南北相位设计)；另一种是各进口单独放行的相位设计形式。Optionally, the signal phase information of each intersection can also be determined, that is, the signal phase scheme. The so-called signal phase means that within a signal cycle, one or several traffic flows will obtain exactly the same signal light color display at any time. Then the continuous timing sequence in which they obtain different light colors (green light, yellow light, full red) is called a signal phase. Usually, there are two types of phase design forms: one is the phase design form of symmetrical flow release (referred to as the symmetrical flow release phase form), which is further divided into left-turn phase design, right-turn phase design, and pedestrian and non-motor vehicle phase design. , east-west phase design, north-south phase design); the other is a phase design form in which each import is released separately.

其中，所谓绿信比，即交通灯一个周期内可用于车辆通行的比例时间，即某相位有效绿灯时间和周期时长的比值。可选的，在确定了交叉口在主道路方向上的显示绿灯时间后，即可根据主道路方向上的显示绿灯时间算出主道路方向上的有效绿灯时间，同样的，在确定了交叉口在次道路方向上的显示绿灯时间后，即可根据次道路方向上的显示绿灯时间算出次道路方向上的有效绿灯时间。其中，每一交叉口的主道路、次道路可以预先设定。Among them, the so-called green signal ratio refers to the proportion of time that a traffic light can be used for vehicle traffic in one cycle, that is, the ratio of the effective green light time of a certain phase to the cycle length. Optionally, after determining the green light time of the intersection in the direction of the main road, the effective green light time in the direction of the main road can be calculated based on the green time of the intersection in the direction of the main road. Similarly, after determining the time of the intersection in the direction of the main road, After the displayed green light time in the secondary road direction, the effective green light time in the secondary road direction can be calculated based on the displayed green light time in the secondary road direction. Among them, the main road and secondary road of each intersection can be preset.

Time and effective green light time, etc., the time distance diagram of signal timing-distance between intersections can be drawn to determine the width of the green wave and the speed of the green wave. The so-called signal timing-time distance diagram of the distance between intersections, that is, the horizontal axis is the signal timing, and the vertical axis is the distance between important intersections; the slope of the two oblique lines obtained is the speed of the vehicle traveling along the main road, and the speed line The calibrated time range is the passing zone, and the bandwidth is called the green wave width, which is the passing time that can be utilized by the main road traffic flow.
步骤16：将所述绿波车速发送给所述出行车辆。Step 16: Send the green wave speed to the traveling vehicle.
在确定出绿波车速之后，即可通过路侧单元等将绿波车速发送给出行车辆，出行车辆上的车载单元接收绿波车速，从而引导驾驶员按照绿波车速行驶，减少出行车辆遇到的红灯的数量，从而提高车辆的出行效率，减缓交通拥堵状况。After the green wave speed is determined, the green wave speed can be sent to the traveling vehicle through the roadside unit, etc., and the on-board unit on the traveling vehicle receives the green wave speed, thereby guiding the driver to drive at the green wave speed, reducing encounters with traveling vehicles. the number of red lights, thereby improving vehicle travel efficiency and alleviating traffic congestion.
