TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 307: Systems Engineering Processes for Developing Traffic Signal Systems discusses the systems engineering techniques available to traffic signal systems and identifies the key processes in a number of traffic signal systems engineering areas.

The primary focus of the manual is on "how to conduct" transportation engineering studies in the field. Each chapter introduces the type of study and describes the methods of data collection, the types of equipment used, the personnel and level of training needed, the amount of data required, the procedures to follow, and the techniques available to reduce and analyze the data. Applications of the collected data or information are discussed only briefly. The focus is on planning the study, preparing for field data collection, executing the data collection plan, and reducing and analyzing of the data. Guidelines for both oral and written presentation of study results are offered.
