Abstract： In order to propose effective countermeasures for moped violations, this paper investigates the moped riders’ behaviors through videotaping at 12 signalized intersections in Shanghai. The paper encodes the characteristics of riders, mopeds and traffic environment based on the behavioral analysis method and analyzes the factors affecting moped violation behaviors using the Logit model. The results show that 1) shorter cycle lengths, smaller non-motorized traffic volume and less conflicting traffic may increase the probability of moped red light running; 2) moped riders tend to wait improperly when the through lanes or the non-motorized lanes are narrow; 3) when the turning lanes or the non-motorized lanes are narrow or the conflicting traffic is light, the probability of mopeds using wrong lanes may increase; 4) broader non-motorized lanes may increase the probability of moped retrograde motion; and 5) fuel or gas vehicles and male riders increase the probability of moped overloading. Finally, the paper points out that safety consciousness for moped riders, traffic laws and rules, and traffic facilities should be improved to guide an ordered and safe urban transportation system.
