today’s, a common problem in cities is increasing delay and reducing the speed of traffic. on the other wise increasing costs of acquisition in urban area are not allow new routes and highways. also construction of new highway or street such as imam ali highway and sadr highway in tehran lead to develop new applications (such as brt lane ,…) and become quickly saturate and less efficient. there...

IN T R O D U C T IO N The major material utilized in the construction of the roads, streets and highways of this country is asphalt. Of the nation’s 3.84 million miles of roads, 1.86 million are paved, hard-surfaced structures. 1.74 million or 94% of these paved roads are constructed of asphalt (Fig. 1). Likewise, within the state of Indiana, 83% or about 9300 miles of the 11,200 miles under th...

We consider the problem of labeling dynamic (3D) maps: we develop real-time algorithms that attach non-overlapping annotations to objects on maps which the user can pan, zoom, and rotate continuously. Existing algorithms either label static maps or only a small number of the objects. We consider the problem to label streets and to label points. We label streets either internally or externally. ...

The validity of the mobility model used to evaluate a cellular network determines the validity of the evaluation. In the literature, unrealistic assumptions on mobility are exercised for the sake of simplicity. In this paper, we present a novel mobility model which is realistic in the sense that it captures the moving-in-groups, conscious traveling and inertial behaviours of the subscribers whi...

OBJECTIVES Spatial assessment of traffic noise pollution intensity will provide urban planners with approximate estimation of citizens exposure to impermissible sound levels. They could identify critical noise pollution areas wherein noise barriers should be embedded. The present study aims at using the Geographic Information System (GIS) to assess spatial changes in traffic noise pollution in ...

Modeling a city poses a number of problems to computer graphics. Every urban area has a transportation network that follows population and environmental influences, and often a superimposed pattern plan. The buildings appearances follow historical, aesthetic and statutory rules. To create a virtual city, a roadmap has to be designed and a large number of buildings need to be generated. We propo...
