If traffic is congested, then the system changes the signs to direct motorists to stay in two lanes as they approach the work zone.This maintains efficiency since vehicles can merge without conflict with one another. If traffic is flowing freely, then the system directs motorists to merge early into a single lane before they enter the work zone.In this system, large, changeable message signs provide one of two messages, based on the conditions of highway traffic flow: ![]() ITS work zone systems maintain safety and traffic flow using dynamic lane merge systems. Include work zones in your traffic incident management (TIM) coordination plans and TIM operations. This is especially useful if the work zone is taking place in a location not covered by another camera monitoring setup. Agencies can install additional, portable cameras and communication devices to send extra information to a centralized location where agency staff monitor and respond to traffic demands and incidents in real-time, called a traffic management center. If an incident restricts traffic even further, it can result in major congestion and delays. Managing incidents is important in work zones, especially when the project requires a lane reduction. Inaccurate information can result in increased congestion and other traffic issues, and those involved can lose confidence in future communication after a confusing experience navigating a work zone. Agencies can provide traveler information using message boards on the roadway, or online through websites and apps. It is critical for the public to have accurate, up-to-date information about construction projects. ITS technologies are used in work zones for a variety of purposes, for example: It then uses the information to make decisions about how to manage the work zone. ITS includes the use of electronics, computers, and communications equipment to collect and process information. Using Intelligent Transportation Systems (ITS) in work zones can improve the safety and mobility in and around transportation-project construction zones.
