• Mixed road traffic with a high proportion of motorcycles is a typical vehicle composition in Hochiminh City, Vietnam. Due to the nature of such a traffic stream, the method commonly used in evaluating the efficiency of traffic signals cannot be adopted here. Motorcycles are performing differently to traffic signals compared with passenger cars; in particular, their advanced mobility and flexibility resulted in a failure of the application of traditional traffic signal evaluation tools. This paper attempts to report a new approach for the issue; using a modified Passenger Car Equivalent unit (PCE) to convert motorcycles into standard car unit. Then aaSIDRA is applied to conduct a standard evaluation process on the performance of traffic signal designs; a range of output from aaSIDRA can be used to compare the differences with different signal settings. Finally, using the developed PCE factor, queuing and delay measured from aaSIDRA can be converted back into motorcycle delays.
