Dissipating traffic congestion of emergency events through information guidance on mobile terminals

This paper presents emergency events in the urban road traffic system caused by bus delays buses and consequent congestion problems. It intends to dissipate the traffic congestion of passenger transport network. For the purpose of keeping the order of transit passengers and improving efficiency of transit service, it is important that transit passengers obtain the travel information when transit service is interrupted or delayed. There is also a need for the public transportation authority (PTA) to know how to use travel information to guide the passenger flow assignment and coordinate transport dissipation. This project builds emergency traffic congestion scenarios and adopt the Stated Preference questionnaire to acquire passenger's travel demand information and distinguish sensitivity of demand factors. Then, it researches on the mechanism of sending group short messages (SMS) including partitioned methods, published time, contents and frequency to bus passengers using mobile terminals. This paper also presents published regulation of group short message sending on mobile terminals in emergency traffic events to PTA.
