Abstract EN
Toxic gas leakage has diffusion characteristics and thus dynamically affects surrounding zones.
Most of current evacuation traffic management models set the road risk level as a static value, which is related to the distance to the hazard source, or a dynamic value, which is determined by the toxic gas concentration.
However, the toxic gas propagation direction is not considered, and this may lead some evacuees driving from less dangerous regions to higher dangerous regions.
To address the shortcomings of traditional evacuation traffic management models, this paper proposes an improved road risk level assessment method based on the difference of the risk levels of upstream and downstream zones of road and develops a safer evacuation traffic management model under the diffusion of toxic gas.
The Cell Transmission Model (CTM) is used to depict the evacuation traffic loading process.
A numerical test is carried out on Nguyen and Dupuis Network.
The test results show that the improved road risk level assessment method can avoid the evacuees driving into higher risk level regions from less dangerous regions.
