郑州裕国路与延祥路车流量交通指数数据

主要包括裕国路与延祥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) ，通过分析来向、去向交通指数，可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 covers traffic flow data of each direction at the intersection of Yuguo Road and Yanxiang Road, which is collected by counting vehicles entering and exiting the detection area, and is used to control real-time scheduling of traffic signals based on vehicle entry and exit data.

Dataset Purposes:
1. Provide raw data for later re-dividing traffic signal timing periods, adjusting period durations and current green split ratios (defined as the ratio of green time available for vehicle passage within a signal light cycle to the total cycle duration):
1) For weekdays (Tuesday to Thursday): Divide traffic flow into time segments based on the ratio of the two-day preceding traffic flow data of each direction to the intersection's designed saturation flow value;
2) For weekdays (Monday, Friday to Sunday): Divide traffic flow into time segments based on the ratio of the traffic flow data of each direction on the Monday of the preceding two weeks to the intersection's designed saturation flow value;
2. Calculate lane time occupancy based on the traffic flow of each time period, and estimate lane space occupancy and headway;
3. Provide intersection traffic flow, lane occupancy and other data required for traffic department decision-making.

Data Sources:
1. Traffic flow (i.e., the total number of vehicles detected by flow detection coils): Left-turn, through, right-turn and outbound traffic flows can be monitored and collected through the software backend, while inbound traffic flow needs to be calculated;
2. Saturation flow (i.e., the maximum number of vehicles that can pass within 10 minutes): It is a fixed value based on previous measurements;
3. Inbound and outbound traffic indices need to be calculated via corresponding formulas.

Data Processing and Application:
Inbound traffic flow (a1) = left-turn traffic flow (a3) + through traffic flow (a4) + right-turn traffic flow (a5);
Outbound traffic flow (a2);
Inbound traffic index = (a1 / 1476) * X; Outbound traffic index = (a2 / 776) * X (the value range of X is 1 to 3). By analyzing the inbound and outbound traffic indices, reference basis can be provided for optimizing traffic light timing, improving traffic efficiency and achieving sustainable development.
