Car ownership and use in the Kingdom of Saudi Arabia (KSA) are very high due to income, low fuel prices near absence public transportation Kingdom. Currently, is going through a massive transformation entering new era national reforms. One main aims reforms reduce car dependency enhance more sustainable options travel such as KSA. In order achieve an aim, there two hurdles: Firstly, must be pro...

We conduct a cross-sectional ecological analysis to examine environmental correlates of active commuting in 39,660 urban tracts using data from the 2010 Census, 2007-2011 American Community Survey, and other sources. The five-year average (2007-2011) prevalence is 3.05% for walking, 0.63% for biking, and 7.28% for public transportation to work, with higher prevalence for all modes in lower-inco...

one of the main challenges facing urban planning in the late 20th century is the growth rate of traffic that influences access to sustainable urban development. one of the solutions proposed for traffic—as well as the economic, social, and environmental problems originating from it—in large cities has been the applying of traffic restrictions during certain times and in specific places in order...

The existence of a series of problems in transportation management of public and personal vehicles causes to consider intelligent transportation systems. Hence, here we investigate to introduce and the performance of intelligent transportation system ITS which is among new technologies in information technology and at last the importance and necessity of lack of delay in data and informat...

Finding new ways for traveling at a high commercial speed, comfortable, safe, cheap and preserving as much as possible the environment by using less fuel is the new challenge for the public transport operators that run their business in the 21st century. One of the alternatives for the passengers that are using public transportation vehicles is to travel using water buses or ferries. The paper ...

This paper presents polynomially solvable stochastic models to tackle the Vehicle Sharing System (VSS) pricing problem. We focus on optimizing the average number of trips sold with static demands, infinite station capacities and null transportation times. The stochastic VSS pricing problem is modeled as a closed queuing network with infinite buffers and continuous controls on transition rates f...
