Mechanism Analysis of Vehicles Operating Characteristic affected by the Visual Environment in Urban Underground Road Based on Information Load

Abstract:

Driver visual information load in different road environment is calculated and mechanism of vehicles operating characteristics affected by the different road environment is analyzed in this paper. The purpose is to improve technical design and operational management level in underground roads. Firstly, vehicles operating characteristic and visual environment information are obtained with naturalistic driving on underground and aboveground road. Comparative study about vehicle operation characteristics and driver visual information load are carried out. The relationship between visual information load and vehicle operation characteristics (headway space and operating speed) is researched. Secondly, influence mechanism vehicles operating characteristics affected by visual environment in underground road is analyzed; Lastly, the measures improving and enhancing underground traffic security is proposed based on driving simulation.
