In order to improve the travel service quality of conventional bus, an optimization model of buses’ flexible departure intervals considering crowdedness state in the bus is established. By quantifying the crowdedness state in the bus, the travel cost under each crowdedness state is given, and the crowdedness state transfer function of each section of the line is established. Considering passengers’ perception of the crowdedness state in the bus, the measurement model of the number of passengers getting on and off the bus over time is established;the travel cost measurement model is established, and the optimization model of buses’ flexible departure intervals is established with the objective function of minimizing the sum of passenger travel cost and vehicle operating loss;and the genetic algorithm is designed to solve the model. The results show that the optimization model can effectively reduce the travel cost.The model has a"short board filling"effect on the waiting cost, and a"peak cutting"effect on the travel cost. That is, by increasing the waiting cost of the stop with fewer passenger arrivals, reducing the waiting cost of the stop with more passenger arrivals and weakening the peak value of the travel cost, the total cost can be minimized.

In order to more comprehensively analyze the visual effect of different areas of the guide sign layout, a "Chinese character plate height ratio" is proposed to characterize the coupling relationship between the height of the Chinese characters on the sign board and the height of the sign board. From the perspective of the recognition characteristics, the region of interest on the sign layout is divided. The conditional generalized variance minimization method is used to screen the low-relevant visual indicators as evaluation indicators. The principal component analysis method is used to establish the comprehensive evaluation index of different driving speeds and draw the trend chart of visual effect. Studies have shown that the trend of visual effect on the left side of the sign board is opposite to that on the middle and right sides, and the visual effect on the right side is higher than which on the middle side; at a driving speed of 50 km/h, the overall visual effect of the sign layout is higher, and the recognition time is least affected by the Chinese character plate height ratio.
