  • Improved Operations through ITS Strategies have a positive impact on reduce travel time delays caused by incidents, as well as reducing travel times during normal conditions. By reducing the amount of time people spend stuck in traffic congestion, fuel consumption, emissions, and driver frustration are all reduced.
  • ITS defined: The application of technologyandcomputer networks to current freeway, traffic, and transit systems to increase the safety and efficiency of the surface transportation system.ITS uses the Traveler information website mstraffic hosted by MDOT to aggregate information for the public. Build commute routes, view real time streaming traffic camera views, view current incident reports, read current messages on dynamic message boards, etc.
  • The four main goals for the ITS applications throughout the region and state are: Enhance Transportation Mobility, Enhance Environmental Quality, Enhance Public Safety and Enhance Emergency Response. Each of these 4 goals are discussed in more detail in the following slides:
  • MS residents suffer from increased traffic congestion & decreased drive times, especially during special events & evacuations. ITS allows MDOT to squeeze as much operational efficiency from the existing road infrastructure without continuing to build additional lanes. There are many places where additional lanes are simply not possible. ITS technologies improve regional access to community facilities, recreation sites, shopping outlets, hospitals, and military bases. A truly integrated transportation system facilitates multimodal travel opportunities & intermodal goods movement.Often, improving mobility can be attained by simply providing real-time information to travelers that allows them to select their best route and bypass the congested areas. This includes providing information both before the trip and during the trip.
  • Enhance air quality in the region by developing projects that help reduce mobile source emissions & pollutants. The largest source of emissions on the roadway comes from idling vehicles and trucks stuck in traffic. If we can reduce the congestion by better timing and coordination of traffic signals, or quicker identification, response and clearance of incidents then we can have a significant impact on the reduction of emissions and pollutants. Due to this, the overall benefit/cost ratio of most ITS projects is high due to the multiple benefits from the project…..reduced emissions as well as reduced congestion, improved traveler information and a reduction in accidents. (lead in to next slide).
  • 1. Promote the safety of motorist by supporting the allocation of resources to upgrade rail crossing protection and warning systems on major rail lines in the region.Promote the safety of motorists, pedestrians and bicyclists by giving priority to potential projects that would mitigate existing safety deficiencies.There are many different ITS applications that improve traveler safety. In addition to specific safety applications as noted on this slide, other ITS applications and projects can also reduce accidents and significantly increase the safety of our roadways. For example, the traveler information provided to motorists thru dynamic message signs, highway advisory radios, and 511 can warn motorists of slowed or stopped traffic well in advance. This advance notification can significantly reduce the number of rear end accidents as motorists are prepared to stop…or even take an alternate route. In addition, by more quickly indentifying and clearing an incident there is less time for secondary accidents to occur. Speaking of safety….. (lead in to next slide)
  • ITS applications can also significantly improve the responses to all types of emergencies. ITS applications can assist with massive emergency situations such ashurricane evacuations as well as more isolated emergencies or incidents such as overturned trailers or roadway accidents. The ability to more quickly identify the type of emergency, dispatch the appropriate response personnel and clear the situation in a timely manner provides a wide range of benefits to the public. In addition, the overall ITS program will focus on improving the communication and coordination between all the various emergency response agencies and related stakeholders.

  • Poor traffic signal timing contributes to traffic congestion and delay. Conventional signal systems use pre–programmed, daily signal timing schedules. Adaptive signal control technology adjusts the timing of red, yellow and green lights to accommodate changing traffic patterns and ease traffic congestion. The main benefits of adaptive signal control technology over conventional signal systems are that it can:Continuously distribute green light time equitably for all traffic movements.Improve travel time reliability by progressively moving vehicles through green lights.Reduce congestion by creating smoother flow.Prolong the effectiveness of traffic signal timing.FHWA Gives the Green Light to Adaptive Signal Control TechnologiesOutdated signal timing contributes to traffic congestion; this doesn't need to be commonplace. Adaptive signal control technologies can use real-time traffic information to reduce congestion by determining which lights should be red and which should be green.
