Development of a bicycle level of service model from the user’s perspective

South Korea is seeking a solution to the problems of traffic congestion and environmental issues by increasing bicycle use. However, many people feel that using bicycles is inconvenient. Therefore, a bicycle level of service model from the user’s perspective was developed so that the existing bicycle roads can be evaluated and improved. The purpose of this paper is to develop a bicycle Level of Service (LOS) model by considering the user’s level of satisfaction and multiple factors that affect the bicycle LOS. Bicycle LOS criteria are estimated by applying an ordered probit model, which is suitable for research relating to choice. The results with the marginal effect show that the bicycle LOS is largely determined by the width of the road on which the bicycle is ridden. Other factors are also statistically significant in the bicycle LOS, including the road type, the total number of lanes on the approach to the intersection, and the number of encounters (travelers and bicyclists moving in the opposite direction).
