Abstract The tunnel ventilation simulation program and tunnel luminous environment simulation model have been created, in order to investigate how multi-system integration will affect the driving behaviors of drivers in tunnel.Tunnel ventilation simulation is underlain by the tunnel one-dimensional pollutant concentration distribution function. The finite-element numerical solution program for tunnel pollutants concentration distribution is created by using the MATLAB software, so as to determine the pollutant concentration distribution in tunnel. CO and smoke are used as typical pollutants to investigate the mechanism by which pollutants affect driving behaviors, and to establish the quantitative evaluation criteria. Qualitative analysis is conducted by using the state of health of the driver as a criterion for CO concentration assessment, and visibility and driver′s response time are used as the criteria for assessing the impact of smoke. In the tunnel luminous environment model, the tunnel interior scene is created by using the Unity3D platform and virtual driving test is conducted by using the VR device, so as to analyze the driving behavioral patterns in various luminous environments. This study generates a model which reveals how tunnel luminous environment will affect driving behavioral patterns. The results of simulation can be used as reference in rationally designing the ventilation and lighting systems of tunnel and achieving energy-efficient operation of tunnel.
