Motivation
- The impact of congestion caused by the accident is transmitted to subsequent roads, and this congestion propagation is delayed and manifested on some subsequent roads.
- Unpredictable delayed event, lack of histofical irregular event data make the pattern of traffic congestion propagation difficult.
Goal
To identify and quantify the propagation mechanisms and time-lag effects of accident-induced non-recurrent traffic congestion.
Methodology
- Modeling the pattern of traffic congestion propagation caused by non-recurrent traffic accidents.
- Identify the statistical causal relationship between the accident road and the subsequent road, and use the bootstrap method to quantify uncertainties about lags that delay congestion propagation.
