Abstract:

Highway tunnel sections are prone to accidents. In order to reduce safety risk factors generated by tunnels, strict speed limit is implemented in highway tunnels. At present, there is still a lack of research on speed limit standards for expressway tunnel sections.Firstly, this paper analyzes the general situation of highway speed limit in China and abroad, the influencing factors of highway tunnel speed limit settingf, and the driving process into the tunnel.Then a speed limit setting model of highway tunnel considering the constraint conditions of energy saving and emission reduction is proposed, based on the serial influencing factor model, the highway tunnel speed limit setting model is determined by taking the road conditions, traffic conditions, energy consumption and emission factors and environmental conditions into comprehensive consideration and combining with the analytic hierarchy process.Finally, the speed limit scheme of highway tunnel section with the consideration of energy consumption conservation and carbon emmission redectuon is put forward, and some suggestions for setting conditions and constraints of the speed limit scheme are put forward.The results show that the method can be operated and the results obtained are reliable, which can be used as an effective method for the implementation of energy conservation, emission reduction and safety scheme in the field of highway.
