义乌区中新街金桥路车流量交通指数数据

主要包括新街金桥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) 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 includes traffic flow data of each direction at the Xinjie Jinqiao Road intersection, which is collected from statistics of vehicles entering and exiting the detection area, and is used to control real-time traffic signal scheduling based on the entry and exit data.

Applications:
1. Provide raw data for subsequent work including re-dividing time periods, adjusting time period durations, and optimizing the current phase green split (the ratio of green time available for vehicle passage to the entire signal cycle time):
1) For weekdays (Tuesday to Thursday): Divide time periods by segments based on the ratio of the vehicle flow data of the previous two days in each direction to the designed saturated flow value of the intersection;
2) For weekdays (Monday, Friday to Sunday): Divide time periods by segments based on the ratio of the vehicle flow data of the previous two weeks' Mondays in each direction to the designed saturated flow value of the intersection;
2. Based on the traffic flow in each time period, the lane time occupancy can be calculated, and the lane space occupancy and headway can be estimated;
3. Provide data such as intersection traffic flow and lane occupancy required for traffic department decision-making.

1. Data Sources:
① Traffic flow (total number of vehicles detected by flow detection loops): Outbound, left-turn, straight-going and other directions can be monitored and collected via the software backend, while the inbound traffic flow needs to be calculated;
② Saturated flow (maximum number of vehicles that can pass within 10 minutes): It is a fixed value based on previous measurements;
③ Inbound and outbound traffic indexes need to be calculated through computation.

2. Data Processing and Application:
Inbound traffic flow (a1) = left-turn traffic flow (a3) + straight-going 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 between 1 and 3)
By analyzing the inbound and outbound traffic indexes, reference basis can be provided for optimizing traffic light timing to improve passage efficiency and support sustainable development.
