Different research communities varying from telecommunication to traffic engineering are working on problems related to vehicular traffic congestion, intelligent transportation systems, and mobility patterns using information collected from a variety of sensors. To test the solutions, the first step is to use a vehicular traffic simulator with an appropriate scenario in order to reproduce realistic...
Advanced Traveler Information Systems (ATIS) are commonly used nowadays in order to provide various benefits to travelers. Their range of benefits range from more informed travelers on real-time traffic conditions of an area's road network to fuel savings and reduction of emissions. However their effectiveness is strongly rely on their acceptance by the users and the following reaction of the users...
Public lighting in urban environments
accounts for about 50%
of the electricity consumption
in cities, according to the Digital Agenda
for Europeâs report âLighting the
Cities.â Innovative measures are required
to reduce the carbon footprint
and cost of lighting in urban environments.
A promising solution is traffic-
adaptive control of light-emitting
diode (LED)-based streetlights,...
This paper provides an overview of the COMPASS4D project, which aims to deploy cooperative mobility systems in seven European cities. More than 445 vehicles with 807 users and 147 intersections will be equipped. After an one-year full-scale pilot the aim of the pilot sites is to remain operational also after the end of the project. The cooperative services and the system architecture are described...
Public transport systems in modern cities are the key to create the sustainable citizens' mobility of the future. In a short time the private vehicle will be needed only for transportations that public transport cannot be afforded. Supporting the use of the public transport in the cities is one of the main objectives planned by the European Union for next years. It is making an important effort to...
This concept paper discusses the need for a new household waste management system and presents a comprehensive literature review of research that concerns the production of high-tech refuse bins. In particular, The paper uses this literature review to argue the case for a new type of high-tech refuse-bin called ReDbin, for which we present an architectural model, comparing it to two other notable...
Fuel cell electric vehicles (FCEVs) are currently attracting attention as a new form of zero-emission vehicles, just as the commercialization of battery electric vehicles (BEVs) is underway. In the prior 20 years, however, FCEVs failed to be properly commercialized. In this paper, a new approach to the emerging economy of FCEVs and a hydrogen refueling station (HRS) network are studied.
Low Emission Zones (LEZ) are the municipalities' response to the European Clean Air Directive, which obliges regional governments to take appropriate measures to not exceed certain thresholds for pollutants like particle matter (PM), NOX, etc Most LEZ are regulating the access for polluting cars, though the regulations are different and act differently in changing the driver's behavior. Mostly, the...
Within the EC project “iTETRIS”, an architecture for simulating traffic management applications based on vehicular communications (V2X) was designed and implemented. The work was based on evaluating the needs of a real city — the city of Bologna. Applications which try to solve the detected problems were defined and evaluated in subsequent steps. This report describes the evaluation of one of the...
The driving cycle is very useful transportation management field, such as vehicle exhaust emissions evaluation, route planning etc. The GPS (Global positioning systems) is adopted to collect data from trips performed on four routes in Xi'an city. The survey scenario is established combining with vehicle track method and route cyclic method and fit the real world condition of Xi'an as soon as possible...
This paper presents some of the results of CityLog, a European Union project approved in the context of the 7th Framework Programme that is still ongoing and will terminate at the end of 2012. The project is intended to increase the sustainability and the efficiency of urban delivery of goods through an adaptive and integrated mission management and innovative vehicle solutions. Three partners of...
The Asymmetric Traveling Salesman Problem (ATSP) is one of the most studied combinatorial optimization problems. It is a generalized traveling salesman problem in which distances between a pair of cities need not equal in the opposite direction. Since ATSP belongs to a class of NP-hard problems and the optimal solution cannot be found within an appropriate computation time, many researchers have thus...
In Europe, the air transport contribution to the GDP is about 2.6%, while the surface transport represents 11% of GDP. In the Seventh Framework Programme for Research and Technological Development, one of the thematic area is dedicated to the transport systems, with a budget of 4180 million euro. The paper presents a multi-attribute decision model that could be applied to the management of the urban...
Cities around the world have set ambitious emissions reduction targets. They are promoting public transport in order to reduce urban pollution from the transportation sector. Cleaner and less polluting city transit buses are paramount if cities are to attain their ambitious emissions reduction targets, as transit buses are high usage vehicles that operate in heavily congested areas where air quality...
