新疆天鹅湖路与友好路车流量交通指数数据

主要包括天鹅湖路与友好路路口车各方向流量数据由车辆进出检测区域统计而来，根据进出数据控制交通信号的实时调度。用途：1. 为实现后期重新划分时段，调整时段时间以及当前时段绿信比（指信号灯周期内可用于车辆通行的绿灯时间与整个周期时间的比例）提供原始数据；1）工作日周二~周四：根据各方向前两天车流量数据，与路口设计饱和流量值比值，分区段划分时段；2）工作日周一和周五~周日：根据各方向前两周周一当天车流量数据，与路口设计饱和流量值比值，分区段划分时段；2. 根据各时间段流量，可计算车道时间占有率，并可估算车道空间占有率和车头时距；3. 提供交通部门决策所需的路口交通流量，车道占有率等数据。1.数据来源：①交通流量（即流量检测线圈的车辆总和）：去向、左转、直行等可通过软件后台监测收集得到，来向需通过测算得到；②饱和流量（即10分钟最大能通过的数量）：根据以往测算可知，为固定值。③来向、去向交通指数需通过计算。 2.数据处理及应用：来向交通流量（a1）=左转交通流量（a3）+直行交通流量（a4）+右转交通流量（a5）；去向交通流量(a2)；来向交通指数=a1/1476*X；去向交通指数=a2/776*X(X指数区间值为1-3之间) ，当来向交通指数和去向交通指数小于等于3时，车流量属于正常范围，当来向交通指数和去向交通指数大于3以上时，需要根据不同路段和不同时间段来进行分析判断车流量是否拥堵，从而优化红绿灯时间提供参考依据，提高通行效率，从而可持续发展。

This dataset mainly includes traffic flow data of each direction at the intersection of Tian'ehu Road and Youhao Road. The data is collected by counting vehicles entering and exiting the detection area, and is used for real-time scheduling of traffic signals based on entry and exit data.

Applications:
1. Provide raw data for subsequent work including re-dividing time periods, adjusting time period durations, and optimizing the green split ratio of current periods (the green split ratio refers to the ratio of green light time available for vehicle passage within a signal light cycle to the total cycle time):
1) For weekdays: Tuesday through Thursday: Divide time periods into sections based on the ratio of the traffic flow data of the previous two days for each direction to the designed saturated flow value of the intersection;
2) For weekdays: Monday, and Friday through Sunday: Divide time periods into sections based on the ratio of the traffic flow data of the previous two weeks' Monday for each direction to the designed saturated flow value of the intersection;
2. Calculate lane time occupancy based on the traffic flow of each time period, and estimate lane space occupancy and headway;
3. Provide data such as intersection traffic flow and lane occupancy required for traffic department decision-making.

Data Sources:
① Traffic flow (i.e., the total number of vehicles detected by flow detection coils): Outbound, left-turn, through and other directions can be collected via software background monitoring, while the inbound direction needs to be calculated;
② Saturated flow (i.e., the maximum passing volume within 10 minutes): It is a fixed value based on historical measurements;
③ Inbound and outbound traffic indices require calculation.

Data Processing and Application:
Inbound traffic volume (a1) = left-turn traffic volume (a3) + through traffic volume (a4) + right-turn traffic volume (a5); Outbound traffic volume (a2);
Inbound traffic index = a1/1476 * X; Outbound traffic index = a2/776 * X (X ranges from 1 to 3).
When the inbound and outbound traffic indices are ≤3, the traffic volume is within the normal range. When the indices exceed 3, it is necessary to analyze and judge whether traffic congestion occurs based on different road sections and time periods, so as to provide a reference for optimizing traffic light timing, improving traffic efficiency and supporting sustainable development.
