The existence of different types Commercial Vehicles (CVs) in the shared roadway affects traffic flow characteristics differently from other vehicles. Owing to uncertain placement and movement these CVs both longitudinal lateral directions, opportunities for lane changing overtaking by vehicles with lower maneuverability decrease, resulting formation platoons. study's primary aim is assess effe...

T amount of pollution that a vehicle emits is dependent on many factors. The U.S. Environmental Protection Agency (EPA) has developed a series of computer models that estimate the average emis­ sions for different types of highway vehicles. This fact sheet is one of a series on highway vehicle emission factors. It presents average emis­ sion rates for gasoline-fueled and diesel heavy-duty vehic...

In this paper we have studied the electric power steering system for a front wheelsteered, rear-wheel driven four wheels vehicle. A controller has been designed for our model with the help of assist characteristics curves and PID action. We have carried out simulation on different types of vehicle paths which include circular and moose test path. We chose two different cases of steering and for...

The increasing diversity of vehicle type holdings and the growing usage of vehicles by households have serious policy implications for traffic congestion and air pollution. Consequently, it is important to accurately predict the vehicle holdings of households as well as the vehicle miles of travel by vehicle type to project future traffic congestion and mobile source emission levels. In this pa...

Vehicle platoon approaches found in literature deal generally with column formations adapted to urban or highway transportation systems. This paper presents an approach in which each platoon vehicle follows a virtual vehicle, in order to cope with issues such as different platoon geometries. Those different types of formations can be encountered in a wide range of field such as the military or ...
