Abstract The objectives of the System Operations Studies (SOS) of the Automated Guideway Transit Technology (AGTT) program was to develop models for the analysis of system operations, to evaluate AGT system performance and cost, and to establish guidelines for the design and operation of AGT systems. This final report summarizes and documents the work accomplished by General Motors and the Transportation Systems Center in the fulfillment of the Extended System Operations Studies contract. The three main areas covered in this report are: 1) the development of a set of analysis procedures that are supported by the computer models developed during the SOS project; 2) the software changes made to the Discrete Event Simulation Model (DESM) to expand and improve its capability to model guideway transit systems; and 3) the A'aliUkLxou vl Liie ability of the DESM to accurately model vehicle merges an i o modeling custom designed dispatching algorithm. Also inc .u4'gAN®QJ®kT^'^^o is a description of three system level models and their p- »ssible applicatio i to the ahalysis of conventional transit. AUG LIBRARY 17. Key Word* Morgautowu PRT 18.

"'i.j.-W^.lt^, ilWr, \ ':.^(5'S j-k i • PREFACE To examine specific Automated Guideway Transit (AGT) developments and concepts and to build a data base for future decision-making, the Urban Mass Transportation Administration (UMTA) undertook a program of studies and technology investigations called the UMTA Automated Guideway Transit Tech- nology (AGTT) program. The objectives of one segment of the AGTT program, the System Operations Studies (SOS), was to develop models for the analysis of system operations, to evaluate AGT system performance and cost, and to establish guidelines for the design and operation of AGT system. This program resulted in a comprehensive set of AGT system planning and system development models. In order to maximize the benefits resulting from the availability of these models, the model research, development and analysis activity was continued by the issuance of Contract DOT-TSC-1783 in September 1979 for the Extended System Operations Studies (XSOS) to GM Transportation Systems Center. To achieve the objectives of the Extended System Operations Studies project, the model research and development activity was continued through the implementation of software improvements and design changes to the models. Additional model validation activities were accomplished and an analysis procedure which is supported by the SOS models was developed.
