INTRODUCTION Pedestrian behavior and adherence to road traffic regulation is vital in the prevention and control of road traffic accidents (RTA) especially on highways in Ghana. We assessed pedestrians' adherence to road crossing regulations on the George Walker Bush (N1) Highway in Accra. METHODS We conducted a cross sectional study of pedestrians crossing the N1 highway from both sides of t...

The balanced vehicular traffic model is a macroscopic model for vehicular traffic flow. We use this model to study the traffic dynamics at highway bottlenecks either caused by the restriction of the number of lanes or by on-ramps or off-ramps. The coupling conditions for the Riemann problem of the system are applied in order to treat the interface between different road sections consistently. O...

The growth of social activities scale, the increase of population flow and flow velocity, and the continuous development of car industry have brought more and more heavy load to the highway intercity transportation and its management system. Against this backdrop, how to greatly improve the utilization rate of traffic infrastructure and transportation equipment by analyzing and forecasting the ...

The plug-in hybrid electric vehicle (PHEV), utilizing more battery power, has become the next-generation HEV with great promise of higher fuel economy. Global optimization charge-depletion power management would be desirable. However, this has so far been hampered due the a priori nature of the trip information and the almost prohibitive computational cost of global optimization techniques such...

This paper presents a theory for automated traffic flow, based on an abstraction of vehicle activities like entry, exit and cruising, derived from a vehicle’s automatic control laws. An activity is represented in the flow model by the space and time occupied by a vehicle engaged in that activity. The theory formulates Traffic Management Center (TMC) plans as the specification of the activities ...

IN T R O D U C T IO N Today the demands placed on any state transportation or highway agency to provide technical assistance to local communities require very flexible approaches to problem solving. The Ohio Department of Transportation is no exception and as a result we find a much greater need to assure that technical proficiency is maintained within our techni­ cal staff, particularly in the...

Today, modern traffic control systems are necessary to obtain maximum efficiency from the highway system. For the traffic controller to respond to the needs of traffic, it must be able to sense traffic conditions at all times with reasonable accuracy. This vehicledetection requirement has resulted in extensive research and development of vehicular-detection systems. Because of its performance r...
