AI Technical Summary

Technical Problem

In existing technologies, traffic operation risk assessment in highway construction areas lacks continuity and dynamism, making it difficult to accurately reflect the risk propagation and accumulation characteristics along the route, resulting in poor accuracy and reliability of the assessment.

Method used

By acquiring multi-source traffic data of the target area, dividing it into multiple mileage segments along the route, performing spatiotemporal consistency processing and fusion, establishing a segmented coupled risk assessment model, calculating the risk value of each mileage segment, and continuously monitoring the trend of risk value changes, real-time risk assessment and early warning are achieved.

Benefits of technology

It improves the accuracy and reliability of risk assessment, can reflect the spread and accumulation characteristics of traffic operation risks in real time, realize early warning, and ensure the timeliness and comprehensiveness of risk assessment.

Abstract

The application relates to the technical field of data processing, and discloses a highway construction zone risk assessment method and device. The method comprises the following steps: acquiring multi-source traffic data of a target region; wherein the target region at least comprises a construction zone and upstream and downstream road sections of the construction zone; the target region is divided into multiple mileage sections along a road direction in advance; the multi-source traffic data is subjected to spatiotemporal consistency processing and fusion to obtain a fusion data set of each mileage section; the fusion data set of each mileage section is processed based on a segmented coupling risk assessment model to calculate risk values of each mileage section at different time points; the segmented coupling risk assessment model is used for simulating the spatial propagation and time sequence accumulation effect of traffic operation risk along the road direction; the risk values and risk value change trends of each mileage section are continuously monitored, and the mileage sections meeting risk early warning conditions are alarmed. The above scheme can improve the risk assessment accuracy.
