Transit Capacity & Quality of Service
KAI was the prime contractor for TCRP Project A-15, a research effort to develop and document improved Transit Capacity and Quality of Service (TCQSM) principles, practices, and procedures. The research focused on two main areas: (1) developing a new Transit Capacity and Quality of Service Manual (TCQSM), and (2) updating the transit chapters of the Highway Capacity Manual (HCM) for incorporation into the 2000 edition. KAI synthesized existing research pertaining to bus and rail capacity and station design, and developed a new transit quality of service framework that identified the main aspects of service quality from the passenger point of view and provided levels of service for six key service measures. The result of this work was the first edition of the Transit Capacity and Quality of Service (TCQSM), which was released in 1999. KAI was also the prime contractor for TCRP Project A-15A which developed the second edition of the TCQSM and for the TCRP Project A-15C which developed the third edition of the TCQSM.
