       Humanity-Oriented Transportation Development is currently the main principle of urban planning division and road planning. According to the traffic division, Taipei city police department, cases of traffic collision has been tended to increase year-over-year. Most reported cases of traffic collsion are injuries related to pedestrian (hit by a bicycle) due to constrained width of sidewalks. These sidewalks in cities are constructed for shared space of pedestrian and bicycle usage, and in addition, the parking space lots for scooters on a few sidewalks lead different degrees of pedestrian-vehicle conflict. Hence, this study uses the Post Encroachment Time as a conflict indicator to separate the levels base on the degree of risk. The levels of risk are III than quantified base on the arrangement of the parking lot for scooters on the sidewalk, the arrangement of pedestrian and sidewalk configuration, and the exploration of emerging vehicle drivers on the sidewalk. Base on the data of a video clip, three traffic collisions were observed. In this study, we processed a model construction by using multivariable linear regression and ordered logistic regression methods. From the analysis, a high traffic volume, flow rate of pedestrian counts, scooter parking lots, and the separation of pedestrian and vehicles would lead a tendency of increasing the cases of pedestrian-vehicle conflict. However, the confliction would lead to a much more severe situation if the demonstrator is required to prevent one swerves at left and one swerves at right in the parking lot of the sidewalk. In addition, a high rate of involving a conflict from the vehicle is observed from basic statistical analysis, and it is common to see middle and high school students involve a conflict when riding an electrical power assist bicycle. To decrease the rate of pedestrian-vehicle conflict, this study proposed strategies including education, engineering, and law enforcement for improvement. The first strategy, education, is to fully emphasize the concept of respecting each other and the idea of right-of-way as an establishment since young. The second strategy, engineering, is to rearrange the bike lanes from sidewalk to roadway if the width of sidewalk is enough, so that it prevents an invasion of bikes into sidewalks. If the width of the sidewalk is not large enough, a law enforcement can be designed to diminish the pedestrian-vehicle conflict by forcing bikers to carry their own bikes when the traffic volume and the flow rate of pedestrian counts are in a rush hour. The third and last strategy, law enforcement, is to persuade any traffic violations and issue a ban, and terminate any violations and conflicts by using the support of technology law enforcement. This would help vulnerable road users to fairly, reasonably, and safely use sidewalks and achieve the vision of Humanity-Oriented Transportation Development in Taiwan.
