| Abstract | Single traffic flow parameters such as speed, volume and density cannot give a better picture of congestion in itself. And broad, general performance measures are always limited by data absence. As the widespread using of GPS devices, floating car data can be collected as a key data source of congestion performance measures with large sample size, wide coverage and high accuracy. It makes it possible congestion performance measures can be done at different road classes and real time. The detail of the floating car data characters and processing procedure are presented. And "five-dimensional" traffic congestion performance measures are produced with congestion intensity, spatial and temporal distribution, congestion occurring frequency (bottleneck detection) and reliability. A scientific approach for quantitative analysis of urban traffic congestion for inner-city and inter-cities is provided. At last, empirical analysis in Beijing and Shanghai of China are deployed, which verify the feasibility and practicality of the measures and the methods. |

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.
