Evaluation of the impact of ITS
Full text linkThe evaluation of ITS begins and takes root within a European policy focused on the diffusion and enhancement of ITS. This section briefly introduces the history of the European policies and actions supporting these technologies to describe their scope in Europe. ITS apply information and communication technologies to make the transport of people and goods easy and flowing. The potential of ITS was expressly mentioned in several White Papers of the European Commission (EC), which considers them as a way to reduce congestion and bottlenecks. The implementation of traffic management plans, information services before and during the journey, goods management services, assistance and emergency services in case of emergency as well as electronic fee systems is therefore a priority and shall contribute to reduce the saturation of the road network. To support the extension of services in Europe, the European Community supports ITS in the road sector by co-financing several projects. Community policies for the development of the Trans-European Road Network (TERN) aim at establishing the interconnection, the interoperability and the continuity of services, above all on long-distance corridors and at borders. Traffic management advanced systems were implemented before 2001 in many European areas. National and regional ITS services were never coordinated, thus resulting in a fragmented mosaic. Aiming at a wide diffusion of ITS services all over Europe, the EC launched the programme Trans-European intelligent transport systeMs PrOjects (TEMPO) in 2001-2006. The key objective of the programme TEMPO on ITS in the road sector was to promote a harmonious and coordinated development of ITS in the member states of the Union, as well as the cooperation among the several countries, and the safety and quality of the service on the TERN network thanks to the cooperation between bordering regions by means of the so-called Euroregional projects. The programmeTEMPO 2001-2006 includes sixprojects: ARTS, CENTRICO, CORVETTE, SERTI, VIKING and STREETWISE. The project CONNECT and the project ITHACA were added to the six projects, thus covering the whole Europe
The mobility system in urban peripheries with particolar reference to the Italian situation
No full textIn chapter 1 the progress of motorization in Italy is analyzed with particular attention given to the interaction between the possession of vehicles and the territory in urban peripheries. The studies point out how the phenomena of motorization in Italy has undergone a notable growth in the last ten years but an uneven growth between the north and the south and between small towns and cities. In comparison with the European situation it has emerged how high the ownership of automobiles is in Italy. The correlation of the indexes of motorization with the region and residen- tial settlements enables to understand the phenomena of motorization in urban peripheries and in small towns. In a particular way in Lombardy the index of motorization (that is the number of cars owed by each inhabitant) for almost all of the towns differs little from the regional average, thus characterizing Lombardy as a region with high level, diffused motorization.
In chapter 2 the most significant relationships between infrastructures and the use of the region in areas outside urban settlements will be emphasized. In these areas of transition between city and countryside the transportation network and, in particular viability, can be developed with roads fulfilling the needs of the sector but which often do not respect the characteristics of the region they cross

Toolkit for sustainable decision making in its deployment
Full text linkA number of EU-communications have addressed the fact that slow and uncoordinated decision making for ITS deployment on urban, regional and national level is the most urgent problem to be solved in order to utilise the benefits ITS deployment can gain for a sustainable European transportation system.
As lack on easy and efficient access to a wide spread ITS knowledge as well as decision making for the deployment is recognised as the key factors for slow down investment on ITS on administration level.
The toolkit solution presented in this paper addresses one of the most important ITS deployment related challenges on European level: Support and speed up consistent decision making related to ITS deployment for road and public transport (timely, cost-effective, interoperable, positive impact to urban and interurban mobility, positive cost/benefit ratio). It is planned to implement that solution in the 2DECIDE project, which is funded by the European Commission
Analysis of Adaptive Traffic Control Systems Design of a Decision Support System for Better Choices
Full text linkNear half of the world population lives in cities. For many years big cities have faced the dif culties caused by junctions. Junctions and congestion are the cause of many other problems, like air pollution, time waste, delays, increased average trip time, decreased average cruise speed, increased fuel consumption and many others. These important issues cost a lot to governments in terms of both time and money. Cities suffer from the well-known problem of xed-time planning for traf c signals at intersections. In this paper the authors went through these problems and discussed about the dif culties of xed-time plan traf c lights and their solutions. Adaptive traf c control systems are one of the soltions which are exactly opposite to xed-time plans. Four different adaptive traf c control systems will be discussed. Each of them has unique characteristics that make it worthy to compare. The general architecture of these systems is based on a similar concept, but there is a great number of general and detailed differences that makes them interesting to compare. By making a deep comparison between these systems, which is one of the outputs of this research, governments and the authorities in charge can have an appropriate reference to look for their bene ts and choose an adaptive traf c control system to apply to their networks
