FOREWORD The Federal Motor Carrier Safety Administration (FMCSA) Wireless Roadside Inspection (WRI) Program is demonstrating the feasibility and value of electronically assessing truck and motorcoach driver and vehicle safety at least 25 times more often than is possible using only physical roadside inspections. WRI Pilot Tests were conducted to prototype, test, and demonstrate the feasibility ...

The U.S. military, despite spending over $13 billion, appears powerless to stop the Iraqi insurgency’s improvised explosive devices (IEDs), which cause most of the military’s casualties and prevent victory by showing lawlessness and insecurity. However, this view ignores substitution effects we consider here. Using rational choice and expectations models, we find a backward-bending supply curve...

Abstract In this study, the effects of roadside building roof shapes and tree plantings on dispersion vehicle exhaust gas pollution in urban street have been carefully explored. Three typical shapes, i.e., flat, triangle round are considered present work. Firstly, numerical simulations air transport atmospheric turbulent boundary layer with/without vegetation canopy performed using Computationa...

The view that drivers have from the road can be enjoyable or disturbing, stressful relaxing, distracting fatiguing. Road planning guidelines balance aesthetical and safety considerations but are rarely grounded on empirical evidence. This paper reviews evidence effects of roadside visual environment wellbeing behaviour drivers, focusing natural built elements external to road, i.e. excluding ge...

The turbidity of lakes is generally considered to be a smooth function of their nutrient status. However, recent results suggest that over a range of nutrient concentrations, shallow l&es can have two alternative equilibria: a clear state dominated by nquatic vegetation, and a turbid state characterized by high algal biomass. This bi-stability has important implications for the possibilities of...

For some scenarios of vehicle tracking and identification, it is desired that radio-frequency identification (RFID) interrogators can be deployed on roadside lampposts or high poles. In order to meet this requirement, active RFID electronic license plate (e-plate) with a slot-dipole antenna is proposed to provide up-tilted beams. Numerical simulations demonstrate that the proposed e-plate anten...

Background In the state of Victoria in Australia, the development of effective alcohol and driving legislation has produced significant reductions in alcohol related road trauma over the past three decades. The development of drug driving legislation in recent years has followed a similar progression from providing for impairment based enforcement to the recent introduction of random roadside s...
