ABSTRACT

In order to solve the contradiction between tunnel lighting safety and energy saving, this paper puts forward the concept of allowable risk degree, determines the lighting demand based on different risk lighting safety time intervals, and puts forward the calculation model of different traffic flow patterns based on mathematical statistics and vehicle arrival compliance law. The relationship between the traffic volume and the risk degree is obtained by the regression analysis of the characteristic values of different traffic flow patterns. The results are compared with the norm, and it is found that when the allowable risk is 5%, the characteristic traffic quantity value in free flow stage is larger than the norm value. After the free flow stage, the traffic volume value in this paper should first reach the maximum brightness, and then present a two-stage pattern, that is, the brightness decreases with the traffic volume and then remains unchanged after reaching the minimum value, which is different from the standard.
