Recently we have proposed a new transportation system called PRISM (which stands for Program for Individual Sustainable Mobility) to help alleviate traffic congestion and to improve energy efficiency of travel [1]. The system employs privately owned small, dual-mode vehicles that can run on both conventional streets and a dedicated guideway. In this paper we consider an all-electric version for...

1 Nowadays, road transportation sector is responsible for a considerable amount of the total energy 2 consumption, also contributing to about 20-30% of the total man-made CO2 emissions 3 worldwide. 4 In metropolitan areas, the problem is compounded by the effect of traffic congestion. 5 Transport models, online route planners, and the latest versions of on-board navigators do take 6 into accoun...

The single row routing problem is considered. It is shown that the use of backward moves can reduce street congestion when four or more tracks per street are available. We obtain an O((2k)!k*n*log k) algorithm to determine whether or not n nodes can be wired when only k tracks per street are available. An efficient algorithm is obtained for the case when wires are not permitted to cross streets...

This paper explores how the automobile has indirectly led to dramatic changes in patterns of accessibility to retail and service activity within metropolitan regions. The automobile instigated a greater articulation of the hierarchy of transportation facilities, as reflected in a greater differentiation between the local and the regional systems. At the same time, the automobile instigated a co...

In today’s highly regulated cities, a conspicuous pattern of marginal open space has emerged between buildings and streets. With rapid population growth, different activities are also emerging in the spaces, particularly cities developing countries. This study explores informal use spaces along residential streets Ile-Ife, Nigeria, to identify physical planning implications. The data for this w...

Advanced Traveler Information Systems, which have for long been regarded as one of the most promising future applications of wireless vehicular networks for use in the field of Intelligent Transportation Systems (ITS), are effectively becoming part of today’s reality. Many drivers already access the information provided by such systems, for example checking for the state of the streets along a ...

Congestion on roads results in infrastructural deficiencies including massive delays, greater fatalities, and enhanced mental stresses, reduced transit efficiency, increased travel costs. Traffic is a major problem specifically the central area of Lahore city. This study aimed at understanding traffic congestion from stakeholders' perspective suggesting mitigation measures. A sample 365 respond...

Congestion is still a big challenge for urban mobility while vehicle sharing, eCommerce and autonomous vehicles will likely increase the unit veh-km of each density moving on streets. Urban congestion pricing schemes have been taken as effective solutions to this problem. This paper first reviews research application cases through recent years, although with well-developed theoretical basis suc...

Population growth and the massive production of automotive vehicles have lead to the increase of traffic congestion problems. Traffic congestion today is not limited to large metropolitan areas, but is observed even in medium-sized cities and highways. Traffic engineering can contribute to lessen these problems. One possibility, explored in this paper, is to assign tolls to streets and roads, w...
