although there are remarkable differences in drivers’ behavior as well as vehicles characteristics, road capacity estimationmethods in developing countries are same as developed ones. so, the discrepancy between the theoretical andpractical values of capacity is inevitable. although, capacity estimation methods can be classified based on numerousparameters, in developing countries, the availabi...

This paper studies the impact of fuel-cell (FC) performance and control strategies on the benefits of hybridization. One of the main weak points of the FC is slow dynamics dominated by a temperature and fuel-delivery system. Although many researchers have investigated the use of different powertrain topologies, component sizes, and control strategies in fuel cell vehicles, a detailed parametric...

This paper presents a new vehicle detection method from images acquired by cameras embedded in a moving vehicle. Given the sequence of images, the proposed algorithms should detect out all cars in realtime. Related to the driving direction, the cars can be classified into two types. Cars drive in the same direction as the intelligent vehicle (IV) and cars drive in the opposite direction. Due to...

A wide variety of heavy vehicle types—including single-unit trucks, combination trucks with one, two, or three trailers, and buses—operate on U.S. highways. These heavy vehicle types each have unique physical and performance characteristics that interact with highway features. This chapter summarizes the physical and performance characteristics of heavy vehicles. The issues addressed in this ch...

 We consider a pickup and delivery vehicle routing problem (PDP) commonly find in real-world logistics operations. The problem includes a set of practical complications that have received little attention in the vehicle routing literature. In this problem, there are multiple vehicle types available to cover a set of transportation orders, each of which has pickup time windows and delivery time...

Pre-Crash Systems (PCS) integrate the features of active and passive safety systems to reduce both crash and injury severity. Upon detection of an impending collision, PCS can provide an early warning to the driver and activate automatic braking to reduce the crash severity for the subject vehicle. PCS can also activate the seatbelt pretensioners prior to impact. This paper identifies the oppor...
