ITS development working papers 18 25 Moreover the ITS Primer published by the Institute of Transportation Engineers provides valuable information about ITS equipment functions and components The most comprehensive documents for the inspection and maintenance of ITS equipment are the Traffic Control System Operations Handbook published by the Institute of Transportation Engineers and the Testing Handbook for Transportation Management systems published by TransCore These handbooks present a general tutorial to familiarize manual users with fundamental concepts for inspecting and maintaining ITS equipment There are also maintenance checklists for ITS equipment published by the manufacturers departments and subcontractors Edwards and Kelcey have maintenance checklists with rating systems The manufacturers also have checklists 10 that may not be applied for other brands of the same equipment as they are mostly equipment specific Summary of Expert Survey and Interview Results A sample questionnaire and list of expert interviews performed are shown in Appendix B The surveys and interviews provided significant information used in the development of ITSIMM Experts who were interviewed provided a number of comments and problem specific information to each section of the preliminary inspection and maintenance checklists prepared as part of our well structured knowledge acquisition process The most significan

31. al motivation of this study is to provide the New Jersey Department of Transportation NJDOT with a state of the art and practical ITS inspection acceptance and maintenance manual ITSIMM This manual is needed as a reference document to assist the department s inspectors and maintenance personnel and ITS design and traffic operations personnel to ensure effective inspection and maintenance of NJDOT s ITS equipment A wide variety of engineers including civil mechanical electrical software and computer and communication engineers are required to design and construct ITS facilities ITS device manufacturers system vendors suppliers and contractors develop and provide drawings guides manuals inspection procedures and maintenance procedures Thus a vast amount of knowledge must be extracted and then incorporated into a manual of guidelines for effective inspection and maintenance of ITS equipment by knowledgeable experienced NJDOT personnel and well trained inspectors and subcontractors The major goal of this project is to provide these stakeholders with the tools necessary to inspect and maintain New Jersey s ITS equipment The four major goals of our study can be summarized as follows e Acquire the knowledge and experience related to the maintenance and inspection of ITS equipment that reside with New Jersey Department of Transportation NJDOT personnel consultants ITS device manufacturers system vendors suppliers and co
