Background and Aim: High concentrations of particulate matter-25 (PM2.5) have been the cause of the unhealthiest days in Tehran, Iran in recent years. This study was conducted with the aim of the spatio-temporal analysis of traffic volume and its relationship with PM2.5 pollutant concentrations in Tehran metropolis, Tehran during 2015-2018, using the Geographic Information System (GIS). Materi...

Traffic oscillation, stop and go traffic, is created by different reasons such as: sudden speed drop of leader vehicle. Stop and go traffic commonly is observed in congested freeways results in traffic oscillation. Many theories had been presented to define congestion traffic based on laws of physics such as: thermodynamics and fluid. But, these theories could not explain the complexity of driv...

islamic republic of iran, considering specified guidelines in the horizon of the perspective, as pays attention to annually reducing the maximum number of traffic deaths, tries to minimize the rate of traffic fatalities until 2025 horizon. in order to reduce traffic injuries, iranian traffic police ,through preparing resources, inter-organizational coordinations, using modern technologies, usin...

conclusions this study showed that gender, education level, occupation, socioeconomic status, medical care, health condition, lifestyle, family conflict, drug abuse history, and religious attitudes are the major social factors of risky driving on the intercity roads of tehran province. background traffic accidents are the major cause of injuries that endanger the lives of many people annually. ...

one of the most important issues in the plant layout design especially in mass production organizations with high inter-plant logistics is‘material flow and inter-plant traffic analysis and its effects on the production capabilities or pauses in production lines. in this paper the inter-plant traffic analysis issue on the basis of single channel queue model (m/m/1) is analyzed in a carmaker c...

conclusions planning for the prevention of traffic accidents requires standardized data. as the foundation for crash prevention efforts, existing standard data infrastructures present policymakers and government officials with a great opportunity to strengthen and integrate existing accident information systems to better track road traffic injuries and fatalities. results an (mds) of a traffic ...

conclusions atpl was higher in the post-monsoon season. w/s ratio and correlation analysis revealed interseasonal homogeneity of tmv and traffic noise levels and interseasonal heterogeneity of air pollutant concentrations and atpl in the city microenvironments. results atpl was 3.35 times higher in the post-monsoon and 1.83 times higher in the pre-monsoon season than the permissible limits pres...

Traffic congestion in road networks is one of the main issues to be addressed, also vehicle traffic congestion and monitoring has become one of the critical issues in road transport. With the help of Intelligent Transportation System (ITS), current information of traffic can be used by control room to improve the traffic efficiency. The suggested system utilize technologies for real-time collect...

Current standards in microscopic modeling lack the ability to address certain traffic scenarios, the ability to capture discrete differences in driver behavior that exist between various driving populations, and are structured in such a fashion that various vehicle movements are predicted and modeled separately. In this study, effect of social traffic behavior on rate of traffic violation of ...
