This paper attempts to give the solution for the urban scenario using DV cast protocol. Normally DV cast protocol is the best solution for highway traffic. But this paper proposed urban dv cast (UDV) protocol to deal with the urban traffic. This UDV protocol is extension of DV cast protocol. Our aim is to address the urban scenario where vehicles are equipped with sensors or wireless devices to...

Background & objectives: The urban rail transport network is always at risk due to its special conditions. Many cases indicate the existence of threatening and risk factors for human societies in urban rail transportation systems. Therefore, in this study, with the aim of identifying and prioritizing the risks of urban rail transportation networks in order to increase resilience is on the agend...

In the last years, the sensitive increase of congestion phenomena in the urban areas has produced important changes for the role reserved to the public transport. This should become the main tool to solve urban transport problem. Critical phase for the planning of the public transport system is the network design problem (determination of routes and associated frequencies). This step may affect...

extended abstract 1. introduction the important roles played by green space are the social, economic, cultural and environmental aspects of sustainable development. thus, the quality and quantity of green space should be appropriate to the physical size of the city and the needs of society and also it should be developed according to the ecological conditions of the city and its future developm...

Combined with the GPRS (General Packet Radio Service) technology, Geographic Information Systems (GIS) extends its abilities from static to dynamic working environment for urban drainage network. In this paper, a framework of Web-GIS for the urban drainage network management system is presented. This three-layer system framework is based on the J2EE technologies. The principles of data structur...

Due to the inherent discrete nature of sensing, interpolation is a key activity in sensing. Interpolation in urban computing faces an unprecedented inference issue that was not present in large scale traditional sensing environments. Obstacles such as buildings and walls are prevalent in urban sensing, and it is important to consider them in urban sensing interpolation. This paper introduces an...

nowadays, the environmental impact of transportation project and, especially air pollution impacts, are major concerns in evaluating transportation projects. based on this concern, beside definition of traditional objective functions like total travel time and total investment cost, different type of environmental related function is considered as objective function in urban network design. in ...

background : we need a defined population for determining prevalence and incidence of diseases, as well as conducting interventional, cohort and longitudinal studies, calculating correct and timely public health indicators, assessing actual health needs of community, performing educational programs and interventions to promote healthy lifestyle, and enhancing quality of primary health services....

Analyzing the structure and functioning of the urban system revealed ways to optimize its structure by adjusting the relationships among compartments, thereby demonstrating how ecological network analysis can be used in urban system research. Based on the account of the extended exergy utilization in the sector of urban socio-economic system, which is considered as the composition of extraction...

Existing generative mobility models, used to produce mobility data for simulated agents in, e.g., wireless network simulations, suffer from a number of limitations. Most significantly, existing models are not representative of actual human movement. We introduce a new mobility model based on state-of-the-art work in understanding pedestrian mobility patterns in urban areas, known as Space Synta...
