Sustainability

Operation Green light (OGL) is a project that was created by the Kansas City region, and is led
by Mid-America Regional Council (MARC) in Kansas City MO.  The purpose of this project is
to coordinate traffic signals within 20 jurisdictions, on regionally significant corridors to decrease
stops and delays which will help decrease fuel consumption, and emissions. A metro-wide
predominantly wireless network allows the traffic signals to communicate with the central system software.  There were several considerations and issues when implementing this network.

One critical, but often neglected, element in the successful operation of Intelligent Transportation Systems (ITS) is how they should be maintained after deployment. Failure to adequately maintain the ITS infrastructure may result in poor operations and may accelerate device replacement schedules, lessening the realizable benefits of ITS.

Recognizing this, the Oregon Department of Transportation (ODOT) partnered with the Western Transportation Institute at Montana State University-Bozeman (WTI-MSU) to develop a long-range maintenance plan for ODOT’s existing and planned ITS infrastructure. The plan was initiated as a companion effort to the Oregon Intelligent Transportation Systems Strategic Plan: 1997-2017, which identified statewide ITS deployment technologies and practices over the next twenty years.

This paper summarizes the maintenance plan document, highlighting some of the major findings, along with lessons learned during the development of the plan.

Road traffic, as one of the basic preconditions for the development of any city – metropolis, is
entering ever deeper into a phase of failing to be sustainable. Thus, in the City of Zagreb as
well, the number of vehicles in the recent ten years has doubled and is approaching the halfmillion
figure, and the capacities defined by the urban space have remained the same. How to
harmonize the supply and the demand in the field of traffic – this is the basic issue of the city
development sustainability. The work presents the implementation of advanced telematic
technologies (Intelligent Transport Systems - ITS) in the function of guiding vehicles to free
parking spaces in the public garages (PG). The paper provides a proposal for the basic
guidelines of functional specification with special development of the algorithm with realtime
presentation of free spaces.

Toyota City has established the “eco-driving declaration system” to create an environment for
a majority of its citizens to launch ecology-conscious driving. This paper reports on the
effect of the practice and study of measures to promote dissemination of further
ecology-conscious driving.

Emissions from motor vehicles are the primary cause of deterioration of urban air quality. Altering driver behavior can potentially contribute to the reduction of emissions and pollutants. Previous studies revealed that unnecessary acceleration and hard braking inresponse to sudden changes of traffic signals causes significant wasted energy.  Providing drivers with advance information about traffic signal status can potentially result in modifications of driving behavior so that drivers will exhibit smoother driving profiles. These smoother profiles provide benefits particularly by reducing hard braking in front of intersections when the green signal phase ends. This paper, through both analysis and simulation, investigates the potential benefits on emissions and energy consumption of making traffic signal status information available to drivers. Safety benefits of this approach are also discussed.
