This study aimed to estimate the origins of polycyclic aromatic hydrocarbons (PAHs) in size-fractionated road dust in Tokyo. First, seven categories of PAHs sources were defined: diesel vehicle exhaust, gasoline vehicle exhaust, tire, pavement, asphalt or bitumen, petroleum products excluding tire and asphalt, and combustion products except for those in vehicle engines. The 189 source data of 1...

Terrestrial Laser Scanner (TLS) have seen increasing use in survey practices as a means of fast capturing large volumes of point data, with one such practice being the surveying of as-built features for roads. This paper presents methods to automate some of the processing of road scenes. The method focuses primarily on the automation of the identification and extraction process of kerbs and sur...

More people die in road accidents in India than anywhere else in the world [1]. India has 1% of the world’s vehicles, but 6% of the total global RTA deaths [2]. The statistical profile reflects a global estimate of 5.1 million deaths in 2000, due to injuries, accounting for 10% of deaths due to all causes. Out of this a quarter deaths occurred in the South-East Asian region [1]. In fact, road t...

The article presents a mathematical model of the destructive effect wide-profile tire on roadway. makes it possible to adequately reproduce road surface, taking into account load and parameters tire, as well structure surface temperature state.

road traffic injuries are the leading cause of death and disability in the world. so, the aim of current study was investigated the epidemiologic survey of road traffic injuries in patients admitted in al-jalil hospital in aq-qala. this study was conducted on 5774 patients during 2007-2012, to evaluate the profile of 2784 injury patients due to road traffic accidents, admitted in al- jalil hosp...

Original scientific paper Planning of road transport infrastructure is a complex process. One of the major issues is determining the design elements of road infrastructure (road type and number of traffic lanes, cross-sectional profile, etc.). When designing roads, parameters from the international literature are used, containing values derived empirically from local data on traffic flow (mostl...
