In this paper, the traffic flow at an unsignalized T-shaped intersection in which there are three input directions of vehicles and two right-turnings and one left-turning has been investigated by using the cellular automata traffic model. The interactions between vehicles on different lanes and effects of traffic flow states of different roads on capacity of T-shaped intersection system are ana...

Most procedures currently used for the structural and geometric design of pavements fail to treat adequately the effects of mixed traffic on pavement life. The effects of the magpitude$ the configuration, and the number of repetitions of various wheel loads should be included as variables in any good pavement design procedure. An analysis of the axle loads observed on Texas highways is used wit...

results there was a significant positive correlation between increase in the monthly average temperature, the number of rainy days, and the number of frost days with the number of rta (p < 0.05). increased monthly average relative humidity, evaporation, and number of sunny days were negatively correlated with the frequency of rta (p < 0.05). we also observed an inverse significant correlation b...

background : studies have shown that noise pollution has harmful effects on human health. the sound of traffic is the main source of noise pollution in cities. the purpose of this study was to determine noise pollution using a geographical information system (gis) in the main streets of kashan, iran. methods: in this study, 180 noise samples were collected from 20 regions of the main streets in...

Despite the availability of large empirical data sets and the long history of traffic modeling, the theory of traffic congestion on freeways is still highly controversial. In this contribution, we compare Kerner’s three-phase traffic theory with the phase diagram approach for traffic models with a fundamental diagram. We discuss the inconsistent use of the term “traffic phase” and show that pat...
