Four key uses of traffic flow data: planning, control, signal timing, and commercial site selection
The same traffic volume data supports four decision types. This article outlines the required data dimensions, monitoring periods, and criteria for each use case.
1How do you actually use the traffic data you've collected?
The value of traffic flow surveys lies not in data collection itself, but in four key decision-making applications: Traffic planning requires accurate flow data to support urban road design and optimization; Road management relies on real-time traffic monitoring to assist in traffic疏导 and emergency command; Signal optimization uses flow data to adjust timing plans and improve throughput; Commercial site selection analyzes pedestrian and vehicle patterns to inform business decisions.
2Solution: Define dimensions and cycles based on use case
Planning applications require continuous hourly traffic data spanning 7 or more days, covering weekdays and weekends, with breakdowns by vehicle type and direction. Control applications prioritize real-time performance, demanding second-to-minute refresh rates and anomaly alerts. Signal timing requires flow data split by phase to generate time-of-day timing schemes for comparison. Site selection focuses on the temporal structure of pedestrian and vehicle flows, origin-destination distribution, and accessibility of surrounding road networks. The cloud analytics platform offers a range of specialized reports, supporting multi-dimensional, in-depth, visualized, and customizable outputs.
3Data validation: Prove results with before-and-after comparison
After signal timing adjustments, compare traffic volume and average delay at the same location and time period before and after. For implemented control measures, assess using congestion duration and response time for clearance. For site selection decisions, validate predictive models with actual passenger and vehicle flow data post-opening to establish reusable criteria. Data can be exported via open APIs to command dashboards or third-party systems.
Frequently Asked Questions
Supported. The platform offers an open API to retrieve traffic volume statistics by venue and area; third-party dashboards can render data using their own styles.
