Many advances have occurred in the management of road traffic during recent years that present fresh challenges and opportunities that require innovative solutions. This provides an evolving context that presents new constraints, within which new problems occur, and new opportunities for development and improvement arise. It can be seen that traffic management has become more integrated with the users’ needs of the mobility system, in which road users are the ‘actors’ in the system and in which multiple criteria and constraints have to be taken into account. Concurrently, rapid advances in technology have made many new methods available for bi-directional communication and management between different road users, and between road users and management systems. Together with these technical advances, methodologies have also improved in measurement techniques that have made high quality traffic data available, which in turn has made it possible to improve the calibration and validation of traffic models and to extend traffic analysis, modelling and optimisation, these being supported expanding computational capabilities. Those improvements have made it possible to decrease the “granularity” for traffic optimisation and so to take a better and better account of each vehicle or platoon. These developments have resulted in many system experiments and implementations, mostly on a local basis, involving multiple technologies and concepts. This has made it possible to test a wide range of methodologies and techniques, but leaving open a wide area for research and development to take full advantage of the opportunities for improvements that can be achieved through these diverse and individual activities. There is a continuing need for cost-effective, efficient transport providing a wide range of attractive choices to all members of society. Four major issues have been identified: safety, environment, reducing greenhouse gases, and mobility. Each one of these has been addressed to different degrees by large research programs on technological aspects, involving researchers and industry working together. It is now clear that improvements cannot be based only on technological components but must integrate those technological breakthroughs into a more global vision for the optimisation of the traffic system. The NEARCTIS consortium addresses the potential for benefit to travellers and to society as a whole that can be achieved by exploring and developing the potential in these dimensions of improvements to operation of the transport system based upon cooperative intelligent transport systems (ITS). This work package (WP1) has the aim to establish a clear statement of the current state of knowledge and capability in the field. Alongside this knowledge comes an awareness of the gaps in knowledge that correspond to identifiable limitations of current capabilities. These will, ultimately, form the focus of a future integrated multidisciplinary research programme on traffic management and integration of cooperative systems that will be developed and specified, in due course, as part of the work of this consortium. The purpose of the present deliverable D6 of NEARCTIS is to contribute to the basis of this programme definition. The specific objectives are: Elaboration of a common vision of the state of the art Identification of knowledge, and of gaps in knowledge Provision of the knowledge basis to support the specification of a harmonised programme of appropriate research activities. NEARCTIS Deliverable 6 Review of the state of knowledge and capability 15 December 2010 10 This provides a review of the state of knowledge and capability in relevant technologies within members of the NEARCTIS consortium, and through this represents the collective view of teams of researchers in the scientific fields concerned in traffic modelling, traffic control, communication and location technologies. On the basis of this document, the consortium will identify opportunities for technological advance in cooperative traffic management, and through this will specify a harmonised programme of research activities that will be required to support their development. The work package WP1 consists of five tasks. The first four correspond to major research fields, whilst the fifth is cross-cutting, evaluating and identifying the benefits that will arise of the final research programme: 1. Traffic modelling for cooperative systems integration 2. Optimisation and control 3. Positioning, tracking and communication 4. Impact assessment, deployment and implementation issues 5. Evaluation This document (Deliverable D6) reports on the results of the knowledge gathering and review exercise undertaken in the area of cooperative traffic management research. The structure of the present report is based around considering in turn each of the following topics. Domain definition Common view Identification of knowledge Gaps in knowledge This review leads us to develop a view of the needs and prospects for further research in order to realise the opportunities presented by cooperative ICT in traffic management.
