R. W. “Bob” Rivers (Inspector, Officer-in-charge, Traffic Branch, Royal Canadian Mounted Police - Retired) is the author of various internationally recognized and utilized traffic crash investigation and reconstruction textbooks published by Charles C. Thomas, Publisher, Ltd., Springfield, Illinois, and the Institute of Police Technology and Management (IPTM), University of North Florida.

As an IPTM adjunct faculty member, he acts as a technical advisor, directs IPTM's correspondence training programs and carries out various projects such as the development of traffic crash investigation courses and Traffic, Crime Scene, Marine and Aircraft crash investigation templates.

Bob Rivers travels internationally, carrying out research involving traffic crash investigation and reconstruction training programs. Upon request he will provide assistance, advice and/or suggestions on an international basis in terms of training programs and arrangements for lecturers/speakers for Accident Investigation and Accident Reconstruction related seminars and conferences.

Inspector R.W. “Bob” Rivers is the author of: Traffic Accident Investigator’s Manual: A Levels 1 and 2 Reference, Training and Investigation Manual; Traffic Accident Investigators' Lamp Analysis Manual; Technical Traffic Accident Investigators' Handbook: A Level 3 Reference, Training, and Investigation Manual; Traffic Accident Investigators' and Reconstructionists' Field Measurements and Scale Diagrams Manual; On-Scene Traffic Accident Investigators' Manual; Basic Physics: Notes for Traffic Crash Investigators and Reconstructionists : An Introduction for Some a Review for Others; Evidence in Traffic Crash Investigation And Reconstruction: Identification, Interpretation And Analysis of Evidence, And the Traffic Crash Investigation And Reconstruction Process; and, Tire Failures and Evidence Manual: For Traffic Accident Investigation.

According to the description of Traffic Accident Investigator’s manual: A Levels 1 and 2 Reference, Training and Investigation Manual, “many traffic "accidents" are someone's fault. Some are intended, while others can be foreseen. It is the traffic accident investigator's role to determine, through the gathering of evidence and an analysis of circumstances, that which is an accident and that which is not. This manual launches the trainee on the road to the scientific approach to determining which incident falls into what category. The text clearly outlines the steps to be taken when the report of a traffic accident is received, travelling to the scene, the at-scene investigation, and any follow-up investigation that may be required. An introduction to scientific speed analysis based on thorough at-scene investigation is provided.

According to the description of Evidence in Traffic Crash Investigation and Reconstruction: Identification, Interpretation and Analysis of Evidence, and the Traffic Crash Investigation and Reconstruction Process, the book “begins with a detailed description of the entire investigation process. The material then graduates into the various phases and levels of investigations, showing the levels of training and education normally associated with the levels of investigations and consequently the duties and responsibilities of the investigator and reconstructionist. Using narrative, schematics, and photographs, the mechanical inspection process is described in detail by identifying various vehicle parts, explanations of their functions, and methods of identifying failures. Human-related factors in traffic crash investigations are discussed at length, including the traffic crash viewed as a systems failure. Looming vulnerability, a recently developed theoretical construct that helps to describe and understand social, cognitive, organizational, and psychological mechanism, is described.”
