Headway or inter-arrival time of vehicles is an important parameter in traffic flow, especially in urban roads, since this is one of the main parameters to determine the minimum (safe) gap between vehicles and the capacity. The studies done on headway analysis have mostly concentrated on homogeneous traffic where the flow follows lane discipline. This ideal situation does not exist on Indian ur...

Today, one of the main applications of multi-source aerial data is the city modelling. The capability to automatically detect objects of interest starting from LiDAR and multi-spectral data is a complex and an open problem. The information obtained can be also used for city planning, change detection, road graph update, land cover/use. In this paper we present an automatic approach to object ex...

Traffic jams are a severe problem affecting cities around the world, and they are only getting worse as the population and number of vehicles continues to increase significantly while the area available for building roads does not. Annually, many citizens waste countless hours stuck in traffic, and the amount of time spent is expected to increase. One study calculated that in 75 different city ...

Generalization is certainly one of the most important current issues in cartography, with particular emphasis being placed on its automation. This paper considers the automation of generalization applied to road networks primarily urban roads. In this context car navigation is considered as main subject. As Timpf et al. (1992) stated car navigation require data at a wide range of scales and at ...

With advances in modern technology, fuel consumption will drop with a resulting decrease in state and federal income from motor fuel taxes, decreasing the revenue available to maintain and improve the transportation infrastructure. To keep pace with future transportation needs, a new funding mechanism is needed to supplement or replace the current road financing mechanism. One possible approach...

Vehicular Ad hoc NETworks (VANETs) belong to a subcategory of traditional Mobile Ad hoc NETworks (MANETs). The main feature of VANETs is that mobile nodes are vehicles endowed with sophisticated “on-board” equipments, traveling on constrained paths (i.e., roads and lanes), and communicating each other for message exchange via Vehicle-to-Vehicle (V2V) communication protocols, as well as between ...

Conclusion It is still axiomatic that the liver constitutes the main cross-roads for the processes of interorgan lipid metabolism, i.e. those processes designed to serve the whole animal as well as individual organ needs. Despite the prime importance of this role, knowledge of mechanisms of regulation of hepatic fat metabolism is derisory. The preceding account has been designed t o highlight t...

Roads are pervasive features of modern landscapes and have major impacts on air, land, and water quality. The United States has >6.2 million km of public roads used by >200 million vehicles (National Research Council [NRC]1997). Road corridors (road plus maintained parallel strips) cover 1% of the United States (NRC 1997) but their direct environmental impacts extend to 20% of the land surface ...

Branch roads, which are densely distributed in cities, allow for the flow of local traffic and provide connections between the city and outlying areas. Branch roads are typically narrow, and two-way traffic flows on branch roads are thus affected when vehicles traveling in opposite directions meet. This study investigates the changes in the velocities of vehicles when they meet on two-way branc...

Settlers of Catan is a board game where the main goal is to collect victory points by building a society of settlements, cities and connecting roads. We have constructed a multi-agent system solution able to play the game and evaluated it against other available bots for the game. Our initial results show that even if the proposed solution does not beat the best monolithic solutions, its strate...
