The paper presents the design of cruise control systems considering road and traffic information during the design of speed trajectories. Several factors are considered such as road inclinations, traffic lights, preceding vehicles, speed limits, engine emissions and travel times. The purpose of speed design is to reduce longitudinal energy, fuel consumption and engine emissions without a signif...

T c = congested link travel time (seconds) T f = free-flow link travel time (seconds) v = link traffic volume (vehicles) c = link capacity (vehicles) α, β = volume/delay coefficients S r c = regular vehicle congested link travel speed (feet/hour) S e c = emergency vehicle congested link travel speed (feet/hour) S f = free-flow link travel speed (feet/hour) u = utilization of road segment in Are...

High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a v...

A heuristic algorithm, called LANCOST, is introduced for vehicle routing and scheduling problems to minimize the total travel cost, where the total travel cost includes fuel cost, driver cost and congestion charge. The fuel cost required is influenced by the speed. The speed for a vehicle to travel along any road in the network varies according to the time of travel. The variation in speed is c...

This paper presents an algorithm for estimating travel time using volume and occupancy data from a series of single inductance loops. The algorithm is based on the statistics of the measurements obtained from a traffic management system. The algorithm produces an estimate of speed and travel time as well as providing a reliability test for the speed estimate.

Multi-path interference due to boundary reflection in shallow water acoustic communication poses a major obstacle to reliable and high-speed underwater communication system. In this study, initially 3D variations of field data such as sound speed, temperature and salinity in horizontal transects of the Strait of Hormuz were analyzed using the ROPME data. Later, data on typical sound speed ...
