Congestion pricing is an important tool for managing demand and providing improved mobility. Gauging the response of those potentially affected by pricing strategies is important to policy makers and implementers of such strategies, both in terms of the public’s opinions and the impact on travelers’ decisions. This paper describes the key role that survey data provide in informing the analysis of congestion pricing. The work is based on the evaluation of five Urban Partners, which the U.S. Department of Transportation (U.S. DOT) funded as demonstration sites for congestion pricing.

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.

Driver’s driving pattern is one the greatest factors determining the fuel consumption and thus carbon dioxide emissions of a heavy-duty vehicle. Difference in fuel consumption can be up to 30 % depending on the driver. Education, monitoring and feedback are ways of guiding drivers towards more fuel efficient driving patterns. An incentive system related to fuel consumption is one way of giving feedback. The greatest challenge facing incentive systems in transportation companies is righteous measurement of driver’s fuel consumption. This study focused on that challenge. As a result of this study an incentive system was developed for the case company, Tampere City Transport. Fuel consumption is the key indicator of driver’s performance in the incentive system. Measurement of fuel consumption is based on groups, which are formed by runs with similar vehicle, route and time of day. Drivers are compared by using a figure calculated from fuel consumptions of their own runs in different groups.

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.

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.
