| Popis: | In recent works on the Internet of Vehicles, “intelligent” and “sustainable” have been the significant in the case of transportation. Maintaining sustainability is always a challenge. Sustainability can be achieved not only by the use of pollution-free vehicular systems, but also by maintenance of road traffic safety or prevention of accidents or collisions. Quantifying the sustainability of urban transport is important as evidenced by a growing number of studies to measure sustainability in transportation. This paper dealt with the challenge of measuring transport sustainability based on the long environmental and safety indicators. To overcome the issue of using too many indicators for evaluation, this paper develops a method for obtaining a composite transport sustainability index for limited sources and time for collecting data. Seven sustainability indicators relevant to urban transport which deal with environmental and social (safety) aspects were selected depending on available data. The indicators were integrated to environmental, social (safety) sub-indices and then to a composite index, in a way that overcomes the limitations on normalization, weighting and aggregation. It is an attempt to quantify transport sustainability for arterials streets within the Hilla network which provides information about current situation of urban transport in different parts of the city. The value of ICST (composite index of transport sustainability) for main arterials at Hilla city (as case study) equal to 0.648, 0.542 and 0.462 for 40th, 60th and 80th streets respectively. The value ICST¬ is the highest at 40th street (inner Hilla city – the best case) and the lowest at 80th street (outer Hilla the worst case). |
