the aim of this study is to evaluate the obstacles due to a dpsir model combined with fuzzy analytic hierarchy process technique. hence, to prioritize the responses regarding the driving forces, pressures, states and impacts, the hierarchy of the model is established. evaluations and prioritization of model results of urban transport situation in tehran have provided a number of necessary issue...

Understanding the relation between vehicle emissions and traffic control measures is an important step toward reducing the potential for global warming, smog, ozone depletion, and respiratory illness. Traffic analysts, through improved roadway design and traffic control, have the ability to reduce vehicle emissions. However, current vehicle emissions models do not allow traffic analysts to easi...

One of the major reasons for accidents is speed. Top of Form Inappropriate speed has been identified as the most important causal factor for serious traffic accidents. Traffic calming measures (TCMs) are engineering measures that are widely implemented to improve road safety by considerably reducing vehicle speed. TCMs have been widely used in urban areas to reduce vehicle flow rat...

I. Introduction Nowadays traffic system will be more complicated to ambulance in the modern world, Because day to day no. of vehicle increasing enormously, To Change the Traffic system it gives huge issue, But To improve the current traffic management as semi-automated traffic system into fully-automated traffic system for and emergency vehicle system by using the Gps, sensor node and message p...

ABSTRACT – Inter-vehicle and vehicle to roadside communication (V2X communication) allow both passenger safety and driving comfort to be improved significantly. For example, a vehicle detecting an icy road could inform following vehicles and thereby prevent accidents. Vehicle to roadside communication could be used near construction sites to warn the vehicle driver about reduced number of lanes...

Robust and reliable traffic monitoring system is an urgent need to improve traffic control and management. Vehicle flow detection appears to be an important part in traffic monitoring system. The traffic flow shows the traffic state in fixed time interval and helps to control the traffic. This paper proposes an automatic traffic monitoring system which is used for estimating the important traff...

Vehicular Ad-Hoc Networks (VANETs), a special kind of Mobile Ad-Hoc Networks (MANETs), where wirelessequipped (road) vehicles form a network without any additional infrastructure. Due to the fast growing number of vehicles and saturation of the transportation infrastructure traffic congestion, accidents and transportation delays become unavoidable. Several measures are implemented in order to s...

Data from the National Hospital Ambulatory Medical Care Survey, 2010-2011. In 2010-2011, the emergency department (ED) visit rate for motor vehicle traffic injuries was highest among persons aged 16-24 years. The rates declined with age after 16-24, with rates for those aged 0-15 similar to those 65 and over. The overall ED visit rate for motor vehicle traffic injuries was higher among non-Hisp...
