This paper presents advancement on the calibration of a models system allowing us to estimate the goods attracted within urban and metropolitan areas. It is a component of a general modelling framework proposed by authors developed in order to support ex-ante assessment of city logistics measures. The primary characteristic of this general framework is the representation of interacting behavior of commodity consumers and commodity suppliers/shippers/retailers. In fact, this framework allows us to simulate goods movements at an urban scale combining urban passenger and commodity flows (commodity flows are generated in order to support a given need), and to investigate the existing relationships among end-consumers and other involved decision-makers (e.g. producers, wholesalers, retailers).

TNT will limit its impact on urban congestion while at the same time reduce CO2 and noise pollution and consolidate good flows eliminating the use of vans and replace them with bicycles and an electric vehicle. This is in order to lead the way in overcoming last mile urban distribution difficulties through creating a best practice in energy reduction by using a mobile consolidation centre.

One of the major obstacles to urban freight demand forecasting is the lack of aggregate-level models that consider commercial vehicle tours. To bridge the gap, this paper describes two variants of entropy maximization formulations that are aimed to estimate the tour flows of commercial vehicles given the number of trips produced by or attracted to each node, and the impedance to travel. The first and second order conditions are derived to gain insight from the entropy maximization formulations. The first-order conditions show that the flow of commercial vehicles traveling along a given tour is a function of the Lagrange multiplier associated with the number of trips produced by each node along that tour, and the tour impedance. The second-order conditions indicate the convexity of the formulations. A case study in the Denver metropolitan area shows the efficiency of this approach: the estimated tour flows closely match the observations with the mean absolute percentage error as 6.71% and 6.61% for the two formulations respectively. Based on the findings, the paper discusses two possible ways of applying this approach to forecast urban freight demand.

A system for modelling commercial movements has been developed for Calgary in Canada. The result is a representation that is novel in this context, including a tour-based microsimulation of individual vehicle movements that provides a wide-ranging and detailed representation and yet avoids explicit consideration of shipments and the related complexities regarding the conversion of commodity flows to shipments, the allocation of shipments to vehicles or routings and the treatment of less-than-load movements and empty vehicles. This development effort drew on the data obtained in a set of surveys collecting information on the roughly 37 000 tours and 185 000 trips (within these tours) made in the Calgary Region by commercial vehicles on a typical weekday in 2001. The resulting system of models includes an agent-based microsimulation framework, using a tour-based approach, based on what has been learned from the data. It accounts for truck routes, responds to related policy and provides insight into aspects of commercial vehicle movements. All types of commercial vehicles are represented, including light vehicles, heavier single unit and multi-unit configurations. All sectors of the economy are incorporated, including retail, industrial, service and wholesaling. This modelling system is integrated with an aggregate equilibrium model of household-related travel, with the microsimulation processes done in external Java applications.

Quantitative analysis of traffic conditions provides benchmark in evaluating traffic states for effective operation and management, while the majority of existing studies was focused on measuring congestions of freeway continuous traffic flow. This paper aims to quantify states of urban interrupted traffic flow by using the field traffic data from arterial roads in Changzhou, Jiangsu province, China as a study case. The Average Congestion Index (ACI) indicator was developed by considering traffic volumes on different segments to reflect congestion state of entire road. Then, in combining with the Congestion Travel Rate (CTR), which reflects the difference between the studied state and free flow state, the two indices were adopted to measure congestions quantitatively for both weekday (Mar. 24, 2010) and weekend (Mar. 28, 2010) traffic. In addition, Fuzzy Clustering Method (FCM) was used to obtain threshold values for various traffic states, by which three states were proposed from the empirical study on the traffic conditions in Changzhou. Under this classification, congestion quantifications of field observed trends from both weekday and weekend were found to be consistent with the definitions from Urban Traffic Management Evaluation System of China (UTMES). This further validated the effectiveness of the proposed ACI indicator.

This paper brings a preliminary viewpoint on the interface between port cities, urban
regions and their transportation systems in the particular context of Singapore. The development of
the regional Singaporean transactional space includes the province of Johor in Malaysia and the Riau
islands in Indonesia. The resulting spatial pattern and linkages form an Extended Metropolitan
Region (EMR). We present an EMR spatial model where transportation is a key factor explaining
four processes of territorial development, which are densification, dissemination, extension and
contraction. Densification is a process of spatial accumulation of economic activities within an area.
It aims higher levels of productivity. Dissemination is a spatial relocation of unproductive economic
activities towards productive areas. Extension is a space / time collapse enabling economic activities
to extend over a large territory while maintaining low distribution costs. Contraction is a
rationalization of distribution systems facing growing transportation costs and competition from
other systems. Based on the framework provided by the spatial model and available evidence, we
undertake an assessment on transportation and territorial development in Singapore EMR. The
analysis mainly underlines the role of Singapore as a regional transshipment centre and its maritime /
land interface function.

The movement of people, goods, and information within the local metropolitan area is critically important to the functioning of cities. This chapter reviews the U.S. urban experience of the past two-centuries and traces a persistently strong relationship between the intraurban transportation system and the spatial form and organization of the metropolis. Following an overview of the cultural foundations of urbanism in the United States, the chapter then introduces a four-stage model of intrametropolitan transport eras and associated growth patterns. Within that framework, it becomes clear that a distinctive spatial structure dominated each stage of urban transportation development and that geographical re-organization swiftly followed the break-through in movement technology that launched the next era of metropolitan expansion. Finally, the chapter briefly considers the contemporary scene, both as an evolutionary composite of the past and as a dynamic arena where new forces ma already be forging a decidedly different future.

This project builds on the original Career Cluster partnership with the US Department of Transportation. In 1999 the US Department of Transportation took a leadership role in the creation of the National Transportation, Distribution and Logistics Career Cluster. Today they are partnering with the National Association of State Directors of Career and Technical Education by sponsoring the development of Careers in Transportation Curriculum Materials

Public transit policy is based on two objectives: to provide basic mobility for the transportation of disadvantaged, and to serve broader social and environmental goals by reducing car use in metropolitan areas of the United States. Planners, policy makers, and environmental advocates view better public transit as a means to achieve urban planning objectives. This article discusses the outcomes of the past four decades of transit policy. It begins with presenting a short history of transit policy to reveal the evolution of public transit's objectives. It then explores two areas of transit outcomes: impacts on low-income households and impacts on metropolitan spatial structure. Furthermore, it reveals how transit's dependence on public support creates barriers to achieving its societal goals. Finally, the article presents suggestions for designing more effective transit policies. Transit is critical to the economic well being of the cities, it is therefore important that public support for transit continues.
