A Model of the Driving Fault Tolerance of Traffic Management and Control Facilities at Urban Intersections
Abstract:
This paper presents a solution to calculate the traffic management and control facilities fault tolerance ability to driving mistakes due to drivers fault in perception, judgment and operation. Firstly, according to Shannon information theory, the information volume of eight types of contents on transportation management and control facilities are calculated. The total information volume of these eight types of contents is the basic driving fault tolerance of the facilities. Then, the right rate that facilities set and designed, driver conditions and transportation conditions are screened out for correction coefficients. Finally, the actual driving fault tolerance is given by the product of the basic driving fault tolerance and the three correction coefficients. The solution is useful to evaluate the intersection safety level.
