This paper will present the implementation strategy for Intelligent Speed Adaptation (ISA) in Stockholm, and especially our goals and methods for combining ISA with functions for fuel saving and less emissions. As a basis for further ISA implementation, the City of Stockholm has tested active ISA in 20 vehicles. Speeding was reduced with 30% and the acceptance was good. After the trials, the City Council of Stockholm has decided that the goal is to have ISA in all vehicles driving for the City of Stockholm before 2010. An implementation strategy has been accepted which includes an ambition to exploit the possibilities of saving fuel and environment with ISA and also to use this as an argument for implementing ISA. A new concept for how to combine ISA with support for economical driving will be developed and tested in Stockholm. This concept is based on saving fuel by reducing speeding and improving economical driving. Speeding is reduced by the ISA-component and more economical driving will be achieved by combining support before driving (education, incentives), with support during driving (from vehicle computer) and support after driving (statistics, feed-back). “Ecodriving” is not a new concept - the new part is that we can use the ISA-equipment and the ISA-organisation also for ecodriving. This will make it easier and cheaper to implement both ISA and economical driving. The goal is to save at least 10 percent fuel and the corresponding amount of CO2.

Due to economic, environmental and political reasons, there is an increasing demand for zero-emission vehicles. With the wide-scale deployment of electric car systems, a variety of parties with conflicting interests will be interacting, and there will be incentives for dishonest behavior. As a consequence, new technical challenges which are related to IT security and embedded security arise in the context of electric vehicle systems. For instance, payment and metering needs to be secured, privacy needs to be preserved, and the infrastructure needs to be protected. This work investigates for the first time the security threats that must be addressed in intelligent transportation systems, discusses possible solutions, and presents the benefits that IT security provides in this context.

Cities worldwide are plagued by traffic congestion and its numerous negative effects: Traffic delays, inability to accurately forecast travel time, wasted fuel, increases air pollution and carbon dioxide emissions. Blocked traffic may also interfere with emergency vehicles responding to urgent incidents, thus indirectly impacting the health of society. As a result, major cities worldwide have a triple goal of reducing congestion levels, increasing the reliability of travel time information and, a reduction of Greenhouse gas emissions.

Opened in 2007 the Tramway line “Maréchaux Sud” in Paris was designed as an environment friendly, sustainable replacement for a bus line “PC1”, doubling the passenger capacity.

Providing tramway priority at intersections in order to maximize its efficiency while minimizing the impact on other road users (namely cars and buses) was paramount to guarantee the success of the project. This paper describes how these objectives lead to the choice of video-base detectors to identify conditions leading to gridlock situations. It shows the configuration and the operation of the system.

Finally, the paper describes some of the results obtained and details the benefits of the system.

Congestion charging has gained popularity as an effective mean to reduce pollution and to
improve mobility in large metropolitan areas. Congestion charging is already in use in
London (UK), Stockholm (Sweden) and Singapore. Several other cities around the world are
planning to introduce similar schemes. A number of different technologies and architectures
can be used to implement a congestion charging system. This paper gives suggestions as to
what to look for when designing a congestion and discusses issues related to congestion
charging schemes where the solution is based on electronic registration of vehicles.

The automobile is the dominant travel mode throughout the U.S. (1), while transit accounts for less than four-percent of market share (2). Between these principal modes, niche markets exist for other transportation services, such as transit feeder shuttles and carsharing. Commuter-based carsharing, in which individuals share a fleet of vehicles linked to transit, could potentially fill and expand one such niche; complement existing services; and develop into an economically viable transportation alternative. While most transit shuttles rely heavily upon governmental support, carsharing has the potential to become commercially sustainable. In 1999, the first U.S. smart commuter-based carsharing program—CarLink—was launched in the East San Francisco Bay area. Positive program response led to the development of CarLink II—a larger, more in-depth exploration of the commuter model. Program differences include: an increase from 12 to 27 vehicles; a shift from one employer to many; a move from the Dublin/Pleasanton region to the South San Francisco Bay area; integration of seamless carsharing technologies; and an emphasis on economic viability. This paper includes a description of the CarLink field test results, from which CarLink II builds; an overview of the CarLink II pilot program; a discussion of the CarLink II research goals and study methodology; and an examination.
