| Abstract | Among the safety-related applications of vehicular ad hoc networks (VANETs), the Cooperative/Chain Collision Avoidance (CCA) techniques have received special attention in recent years. With CCA systems a fast dissemination of warning messages to the vehicles in the platoon enables them to promptly react in emergency situations. In this way the number of car accidents and the associated damage to drivers and passengers can be significantly reduced. These systems are usually evaluated through simulation. However, to cope with the drawbacks of simulating accidents with current tools based on car-following characterizations, we propose the use of a stochastic model as an alternative to simulation for the design and evaluation of such applications. The model allows the computation of the average number of collisions that occur in a platoon of vehicles, the probabilities of the different ways in which the collisions may take place, as well as other statistics of interest. As shown in this paper, the model enables the evaluation of different scenarios and communication technologies, characterized by using the appropriate distributions for its parameters. The main practical utility of this approach lays on its ability to quickly assess numerically the influence of different parameters on the collision process without the need to resort to complex simulations at a first stage. Such an evaluation provides relevant guidelines for the design of vehicular communication systems. To exemplify it, we provide an evaluation of different types of CCA applications in two scenarios, a freeway and an urban scenario. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
