In the service life of traffic markings, visibility markings can be significantly impacted due to continuous rolling by vehicles. This study aims investigate change retroreflective coefficient at different positions on road after being rolled A two-month follow-up was conducted a specific section road, focusing sideline and middle line lane. The instrument utilized collect data markings. Result...

The modern growth of computer and its related hardware is consequence of the invention of the transistor. The advent of transistor principally revolutionized the hardware engineering by reducing the hardware size and increasing the efficiency. Now, we are swarmed in with the influx of sophisticated computer gadgets and communication devices, combining ingenious ideas and state of the art design...

This paper describes the design and experimental evaluation of a system that enables a vehicle to detect and track moving objects in real-time. The approach investigated in this work detects objects in LADAR scan lines and tracks these objects (people or vehicles) over time. The system can fuse data from multiple scanners for 360° coverage. The resulting tracks are then used to predict the most...

Unmanned Ground Vehicles are tasked with negotiating off-road terrain while satisfying certain objectives, such as maintaining cover and concealment and arriving at a phase line by a designated time. The problem is complicated by the fact that the terrain is typically not known completely in advance, rendering pre-planned routes useless if selected passageways are obstructed. In this situation,...

This article presents a simulation-based framework to model the potential benefits from dynamic vehicle on-line routing in a distributed traffic information system based upon a vehicle-to-vehicle information-sharing architecture. Within this framework, certain vehicles with specific inter-vehicle communication equipment in the traffic network are capable of autonomous traffic surveillance and p...

Vehicle Routing Problem (VRP) is addressed to a class of problems for determining a set of vehicle routes, in which each vehicle departs from a given depot, serves a given set of customers, and returns back to the same depot. On the other hand, simultaneous delivery and pickup problems have drawn much attention in the past few years due to its high usage in real world cases. This study, therefo...

[1] The evolution of engine-generated chemiions in a vehicle tailpipe or in a sampling transfer line is studied and the key parameters controlling chemiion concentration at the exit plane are investigated. We find that the observed higher number concentration but smaller size of nuclei mode particles associated with shorter transfer line residence time, enhanced nanoparticle emission associated...

in front wheels driven vehicles, fuel economy can be obtained by summing torques applied to rear wheels. on the other hand, unequal torques applied to rear wheels provides enhanced safety. in this paper, a model with seven degrees of freedom is considered for the vehicle body. thereafter, power-train subsystems are modeled. considering an electrical machine on each rear wheel, a fuzzy controlle...

Abstract It can be considered that the suspension system is one of most important systems in VEHICLE. Where it responsible for stability and balance vehicle’s structure on roads curves to ensure comfort passengers. Also, absorbs shocks resulting from unevenness road prevents reaching wheelhouse. The influence constructive parameters order obtain smallest level displacements sprung mass has been...
