IN T R O D U C T IO N The highway problem has been the subject of considerable discus­ sion during the past few years and has assumed proportions subject to national concern. This Road School is, in fact, a discussion of this Number One domestic problem. The interest of almost every individual in highways and their operation is increasing, and each year more high­ way technology is made availab...

Tolls are a recurring but not continuous feature in major highway financing policy in Spain. User tolls were the model used to finance the first expansion of the highway network, in the 60’s and early 70’s. The second wave of the highway network expansion took place in the late 80’s and early 90’s. The public budget was the usual source of funds used to pay for the highways built in this period...

Coordination is an essential ingredient of joint activity in humanagent-robot teams. In this paper, we discuss some of the challenges and requirements for successful coordination, and briefly how we have used KAoS HART services framework to support coordination in a multi-team humanrobot field exercise.

This paper demonstrates the requirement of smart tolling systems for smart highway. In smart highway operators and drivers would be able to see in real time the information of traffic. The smart highway is next generation road aimed at Congestion Free, Stop Free and Accident Free through traffic information services. This study defines requirements and functions for development of smart tolling...

We present longitudinal control laws for vehicles moving in an Intelligent Vehicle Highway System (IVHS) [1] [2]. In particular the scenario where cars move along the highway in tightly spaced platoons is considered. We present control schemes that perform the major longitudinal tasks that will be required from the lead vehicle of a platoon moving on an automated highway. More speci cally schem...

We introduce an improved algorithm to locate a segment highway such that the maximum city distance between a given set of n points is minimized (where the city distance is measured with speed v > 1 on a highway and 1 in the underlying metric elsewhere). We consider that such highway is built in a complex transportation system with H other highways and obstacles. The algorithm runs in O(nH(log n...

The cooling performance of the stack radiator of a fuel cell electric vehicle was evaluated under various actual road driving conditions, such as highway and uphill travel. The thermal stability was then optimized, thereby ensuring stable operation of the stack thermal management system. The coolant inlet temperature of the radiator in the highway mode was lower than that associated with the up...

We investigate the traffic flows of the Korean highway system, which contains both public and private transportation information. We find that the traffic flow Tij between city i and j forms a gravity model, the metaphor of physical gravity as described in Newton’s law of gravity, PiPj/r 2 ij , where Pi represents the population of city i and rij the distance between cities i and j. It is also ...
