Terrorist attacks have made security preparedness unquestionably necessary in all cities. While major metropolitan areas have long recognized that their global visibility has required strong security operations, many medium-sized cities, specifically those of the U.S. and European Union, now face the need to establish transportation security frameworks for the first time. This paper assesses the resources available to help medium-sized cities begin the task of creating such systems. This assessment presents infrastructure risk assessment tools, identifies infrastructure and funding resources, and creates a process for developing a security framework to connect agencies responsible for transportation security in these metropolitan areas. Descriptions of transportation security framework practices at the national level had led to the preparation of a transportation security framework for Greenville, South Carolina, USA, to serve as a prototype that other medium-sized cities can emulate. This security framework can serve as either a checklist to ensure security coverage in existing asset management systems and intelligent transportation systems architectures such as those frequently used in the U.S., Europe, and Japan, or it can provide baseline structure for developing a new transportation security framework for cities in developing countries.

Because of the prominent position of urban rail in reducing urban transport-related problems, such as congestion and air pollution, insights into the costs of possible new urban rail projects is very relevant for those involved with cost estimations, policy makers, costbenefit analysts, and other target groups. Knowledge of the differences in costs per kilometre, including explanations of differences and their breakdowns is currently lacking in the literature. This paper aims to provide a first stage insight into how cost per kilometre varies across urban rail projects. The methodology applied is a simple cost comparison across projects where the data collected are comparable. We conclude that capital costs per routekilometre of urban rail vary highly between projects. Looking at European projects and excluding outliers, the total capital costs per route-kilometre (including stations and rolling stock) lie mainly between US$50-100 million (2002 prices). Including US projects, the range is US$50-150 million. The main reasons for the high variation in the route-kilometre costs are differences between projects as regards the ratio of underground to above-ground construction, ground conditions, station spacing, type of rolling stock, environmental and safety constraints and labour costs. We warn, however, that the observations used to reach the conclusions are too few to obtain results with statistical significance. Our results must therefore be seen as a first step towards collecting more data so that a more succinct statistical analysis can be conducted. Another conclusion is therefore that this area has future research potential.

This research aims to develop a valid method to examine the relationship between transportation infrastructure and economic growth through the measurement of the economic boundary of a freeway industrial zone in developing countries. By comparing the similarities of a freeway industrial zone with an electromagnetic field, the Boit-Schwander law in electromagnetism is applied to create an electromagnetic model, which can calculate the attractive effect caused by a freeway on its influential area. When the attractive effect is equal to the traffic impedance, the economic range of the industrial zone can be determined by the effective equilibrium approach. An empirical analysis of the Ha-Shuang freeway demonstrates this approach is valid and practical.

The desirable goal in passenger transportation is moving more people in fewer vehicles. This goal, in respect of road transport, can be attained by encouraging public transport modes like buses by assigning priority. This paper is concerned with application of micro simulation technique to study the impact of provision of reserved bus lanes on the flow of highly heterogeneous traffic on urban roads. The specific objectives of this paper are (i) to modify and validate a newly developed model of heterogeneous traffic flow using field observed data and (ii) to apply the validated simulation model to study the impact of exclusive bus lanes introduced on urban arterials for a wide range of traffic volume levels. The impact of introduction of an exclusive bus lane is measured in terms of the reduction in speed of other categories of motor vehicles, due to the consequent reduction in road space, over a wide range of traffic volume. The main finding of this paper is, that if an exclusive bus lane is provided under highly heterogeneous traffic conditions,(prevailing in Indian cities), then, the maximum permissible volume to capacity ratio that will ensure a level of service of C for the traffic stream comprising all the motor vehicles, except the buses, is about 0.53.

This book presents a selection of contributions from a series of meetings of the Network on European Communications and Transport Activities Research (NECTAR) cluster on networks. It is not meant as a book of proceedings, rather it brings together a coherent group of high quality contributions providing a picture of new important research challenges in the field of policy analysis and decision making. This book contributes to our understanding of the state of the art and new developments in policy making for transport networks and the regional impacts of network integration. It emphasizes the central role that evaluation, including cost-benefit analysis and other tools to evaluate policy, play as a decision support instrument. Attention is also given to tools that analyze the impacts of transport policies on accessibility and spatial integration as well as to the vulnerability of the transport network both due to terrorist threats and to natural disasters. The book reviews existing studies and advances in decision support tools in transport policy and in broader evaluation studies of network integration and regional development dealing, with important and challenging issues including the impact of transport projects on regional development, equity and social acceptability, and uncertainty and risk. Understanding of these various complexities in evaluation of transport is imperative for the design of plans and policies that can be used to optimize the efficiency, performance and safety of transportation systems.
