Transportation at Fingertip : Filling the Gap in City Transportation

Allocating city space to multiple transportation modes:

A macroscopic modeling approach is proposed for allocating a city’s road space among competing transport modes. In this approach, a city or neighborhood street network is viewed as a reservoir with aggregated traffic. Taking the number of vehicles (accumulation) in a reservoir as input, we show how one can reliably predict system performance in terms of person and vehicle hours spent in the sys...

The role of integrated management in the realization of intelligent transportation (Case study: Zahedan city)

With the development of cities and increasing population, many challenges have been created, the most important of which is urban transportation. The inability of traditional urban management to address this challenge has led to some approaches, including intelligent transportation. Adopting and implementing such an approach in metropolitan areas requires a change in management approach, of whi...

The Continuing Transportation Study for the Small City

IN T R O D U C T IO N The 1960 Bureau of Census report indicates that 69.9 per cent of the total United States population can be classified as urban. By 1970, this value should be close to 75 per cent. Where has this population increase occurred ? The percentage change for central cities and urban fringes is shown in Table I. Most would agree that the largest per­ centage gain would be in the u...

Fuzzy Transportation Problem with Random Transportation Costs

We consider the following transportation problem with both random and fuzzy factors. There exist m supply points and n demand points. For each route between supply point and demand point, unit transportation cost is a random variable according to a normal distribution and existence possibility denoting the preference choosing this route is attached. The probability that the total transportation...
