Analysis of Bicycle Passing Events for LOS Evaluation on Physically Separated Bicycle Roadways in China

Bicycle contributes 30% to 70% of daily trips in China. Bicycles have their own bicycle lanes built to the right of the motor lanes for each direction of traffic in most cities in China, physically separated from vehicles and pedestrians. Nowadays, they are becoming increasingly busy in many cities. Transportation authorities have been trying to build new or expand existing bicycle roadways to increase bicycle capacity. However, they are in lack of quantitative bicycle Level of Service (LOS) analysis tools designed and calibrated for conditions in China. This paper introduces a LOS evaluation method based on the estimation of the indicator, the number of passing events, according to the bicycle flow characteristics. In our study, the passing events, which were found to be a good indicator of bicycle user's comfort in early literature, can be classified into free passing events, adjacent passing events and delayed passing events, on physically separated bicycle roadways. Models are built to calculate the number of three kinds of events. Passing events data are collected from two physically separated bicycle roadways using random bicycle-following method. Fitted relationships of the field data and the model prediction are compared, and the proposed model is found to be able to effectively estimate the number of passing events. Sensitivity of some key parameters in the model and potential application of the proposed model are also discussed in the end.
