Traffic signal timing is a very complex topic. For example timing a 'WALK' signal for a wide pedestrian crossing and slower pedestrians (for example the elderly) could result in very long waits for vehicles, and thus increases the likelihood of cars running the light, which could potentially cause accidents. Therefore, optimizing the safety of ...
Traffic collision reconstruction is the process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. . Reconstructionists conduct collision analysis and reconstruction to identify the cause of a collision and contributing factors including the role of the driver(s), vehicle(s), roadway and gen
Traffic actuated signal systems use detectors to adjust timing for: Only the main street - semi-actuated system; Both main and cross streets - fully actuated system. The above method is primitive real-time signal optimization at best. This method will optimize one traffic signal at a time.
Traffic signal preemption (also called traffic signal prioritisation) is a system that allows an operator to override the normal operation of traffic lights.The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety.
In some countries including Australia, the road rules outline procedures such as giving way to the right. This system is occasionally used when a traffic signal becomes obsoleted due to a lack of need. Part-time operation: Some traffic lights will not operate at night or when traffic is very light. Some may only operate at particular set times ...
The advanced traffic management system (ATMS) field is a primary subfield within the intelligent transportation system (ITS) domain, and is used in the United States. The ATMS view is a top-down management perspective that integrates technology primarily to improve the flow of vehicle traffic and improve safety.
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
InSync adaptive traffic control system is a real-time adaptive traffic control system that enables traffic signals to immediately adapt to traffic demand. MASSTR (Meadowlands Adaptive Signal System for Traffic Reduction) located in the Meadowlands Region of northern New Jersey will incorporate over 128 signals when complete. As of June 2013 ...
