贵阳林城东路市委路口车流量交通指数数据

主要包括林城东路市委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 in all directions at the Municipal Committee Intersection on Lincheng East Road, which is collected by counting vehicles entering and exiting the detection area, and is utilized to control real-time scheduling of traffic signals based on vehicle entry and exit data. Its applications are as follows: 1. Provide raw data for later period redivision, adjustment of period duration and current period green split (the ratio of the green light time available for vehicle passage within a single signal cycle to the total duration of the cycle). Specifically: 1) For weekdays from Tuesday to Thursday: Divide periods into sections based on the ratio of the traffic flow data of the previous two days of each direction to the designed saturated flow value of the intersection; 2) For weekdays on Monday, Friday to Sunday: Divide periods into sections based on the ratio of the traffic flow data of the same Monday in the previous two weeks to the designed saturated flow value of the intersection; 2. Calculate lane time occupancy based on the traffic flow of each time period, and further estimate lane space occupancy and headway; 3. Provide traffic flow data at intersections, lane occupancy and other relevant data required by traffic management departments for decision-making. 1. Data sources: ① Traffic flow (i.e., the total number of vehicles detected by traffic flow detection loops): The traffic flow data of outgoing directions (including left-turn, straight-going, right-turn etc.) can be collected and monitored via the software backend, while the traffic flow of incoming directions needs to be calculated; ② Saturated flow (i.e., the maximum number of vehicles that can pass within 10 minutes): It is a fixed value based on previous measurements; ③ The traffic indexes of incoming and outgoing directions need to be calculated. 2. Data processing and application formulas: Incoming traffic flow (a₁) = left-turn traffic flow (a₃) + straight-going traffic flow (a₄) + right-turn traffic flow (a₅); Outgoing traffic flow (a₂); Incoming traffic index = a₁ / 1476 * X; Outgoing traffic index = a₂ / 776 * X, where the value range of X is between 1 and 3. By analyzing the incoming and outgoing traffic indexes, reference can be provided for optimizing traffic light timing adjustment, improving traffic efficiency and thus promoting sustainable development.
