We develop a macroscopic model for mixed urban and freeway traffic networks that is particularly suited for control purposes. In particular, we use an extended version of the METANET traffic flow model to describe the evolution of the traffic flows in the freeway part of the network. For the urban network we propose a new model that is based on the Kashani model. Furthermore, we also describe t...

This study identified concentrations, molecular distributions, toxicities, and sources of polycylic aromatic hydrocarbons (PAHs) in road dust from different areas of Ulsan, the largest industrial city in Korea. The total PAH concentrations in industrial areas were dependent on industrial emissions and vehicular exhaust, while those in urban areas were mainly dependent on traffic density, sampli...

Energy Efficiency (EE) of base stations (BSs) in cellular networks is a growing concern for cellular operators to not only maintain profitability, but also to reduce the overall environment effects and economic issues for wireless network operators. In this paper, we highly focus on the EE evaluation of LTE BSs. Then, the parameters that are affecting the EE and the coverage area of LTE BS in d...

The information acquisition of road traffic flow is requisite for urban traffic control and management. Floating car data (FCD) is emerging technique for traffic flow collection of urban large-scale road network, and it can provide effective means to model and analyze road traffic conditions. Map-matching is one of the key techniques for FCD. The typical navigation map-matching algorithms are n...

objectives: to investigate the differences in death after receiving emergency services in traffic accidents between urban and rural regions, and decompose factors of the gap in langerood, northern iran. methods: this cross-sectional study was conducted in langrood, northern iran during a 1-year period from 2013 to 2014. the hospital data of traffic crashes were used. data contained those patien...

in this study which was carried out in 1974 in the province of isphahan a total of 23,273 individuals in the cities, and 18,671 individuals in the villages of the same area were studied. results show that the median age in rural area is 16 and in urban area is 18 years. the birth rate in rural is 27.7 per thousand were as the same rate in urban area is 40.2 per thousand. similarly the general f...

geological conditions of tabriz, a growing city in nw-iran, are strongly influenced by north tabriz fault (ntf). north tabriz fault is a major seismogenic fault in nw-iran. so, for a correct seismic microzonation, shear wave velocity (vs) structure in different part of city should be determined. but urban conditions, such as ambient noise due to cultural activity, restrict the general applicati...
