Abstract:
In order to improve the precision of emergency lane location, this paper thoroughly analyzed influence factors of the emergency lane location from the view of traffic accident statistical data, road conditions and vehicle status, expounded the theory of center-point triangular whitenization weight function, and put forward the grey evaluation model of the emergency lane location. The running safety of the unit section on the long-steep downgrade was evaluated with the model. The unit section of “poor” class was used as the candidate section for setting emergency lane. The accurate positions of the emergency lanes at the end of section 9 and section 20 were determined based on comparison with the gray comprehensive clustering coefficients of adjacent candidate sections. Setting effect of emergency lanes shows that the emergency lane positions determined by the model are scientific and rational. 5 tabs, 2 figs, 10 refs.
