| Summary | In early 2005, the Ministry of Transportation and Communications, Taiwan R.O.C. announced a 6-month trial project of permitting large motorcycles with engine capacity over 250cc to ride on Expressways 68 and 72. Because of the long-term ban of motorcycles from traveling on the expressways, the motorists have very limited experiences in sharing the roads with the motorcyclists. Therefore, it is essential to investigate the traffic characteristics of the large motorcycles on the expressways from traffic management and safety viewpoints. The study results show that motorcycles traveled faster than the other types of vehicles and motorcyclists usually keep a shorter following distance. However, those riding behaviors may not be safety concerns due to the distinction of mechanical characteristics of large motorcycles. A further investigation considering vehicular attributes of motorcycles is essential. Nevertheless, the survey results indicate that the other drivers tailgated the motorcycles as well. This circumstance should be a safety concern because motorcyclists are vulnerable on roads. The inconsistency in signage and installation locations was found in the trial roads. This study suggests that some regulations on large motorcycles should be reexamined, for example two-stage left turn, restriction on the inside lanes while traveling on 3 or more lanes roadways, and restraint to travel urban expressways. In addition, a questionnaire survey was conducted in this study. The results identified tailgating, strong winds, debris on road, lane sharing, and potholes as deteriorating factors for roadway safety. After reviewing and comparing traffic regulations with those of foreign countries, it is important to review and amend the traffic rules and licensing system for motorcyclists, and to enhance the safety education program for motorcyclists and motorists as well. |
