Evaluating Opportunities for Transit Signal Priority in Southern New Jersey

This study examines traffic signal and surface transit routes in Mercer, Burlington, Camden, and Gloucester counties and develops a method of scoring corridors on their likelihood for successful and cost-effective TSP and related signals investments. To develop a TSP prioritization framework, the study team has built upon prior data gathering, analysis, and mapping work. The screening tool identifies the corridors where TSP is likely to be the most effective and have the greatest operational benefits for transit and all road users

Trade Liberalization and Regional Inequality - Do Transportation Costs Impose a Spatial Poverty Trap?

This paper focuses on the spatial impacts of barriers to trade, in the form of tariffs, in a national economy. More specifically, we are concerned with the spatial impediments for the internal transmission of the potential benefits of trade liberalization, in the form of high transportation costs that the more remote regions face. The strategy adopted in this research utilizes a spatial CGE model integrated to a geo-coded transportation model to evaluate shifts in the economic center of gravity and regional specialization in the Brazilian economy due to further liberal tariff policies. Comparative advantage is grasped through the use of differential regional production technologies; geographical advantage is verified through the explicit modeling of the transportation services, as well as increasing returns associated to agglomeration economies; and cumulative causation appears through the operation of internal and external multipliers and interregional spillover effects.

TRADE LIBERALIZATION AND REGIONAL INEQUALITY: DO TRANSPORTATION COSTS IMPOSE A SPATIAL POVERTY TRAP?

In this paper, we focus on the regional (intra-national) impacts of barriers to trade, in the form of tariffs, in a national economy. More specifically, we are concerned with the spatial impediments for the internal transmission of the potential benefits of trade liberalization, in the form of high transportation costs that the more remote regions face. A cost-competitiveness approach, base don relative changes in the sectoral and regional cost and demand structures, is adopted to isolate the likely spatial effects of further tariff reductions in Brazil. It tackles the three basis for the analytical framework proposed in the literature: comparative advantage is grasped through the use of differential regional production technologies; geographical advantage is verified through the explicit modeling of the transportation services and the costs of moving products based on origin-destination pairs, as well as increasing returns associated to agglomeration economies; and cumulative causation appears through the operation of internal and external multipliers and interregional spillover effects in comparative-static experiments, such as those proposed here.

Port Efficiency and Regional Development

This paper attempts to elucidate one of the mechanisms that link trade barriers, in the form of port costs, and subsequent growth and regional inequality. Not only inland costs can be perceived as a further barrier to link trade liberalization and growth (Haddad and Perobelli, 2005), but also port costs. Unlike highway link, congestion at port may have severe impacts spread over space and time whereas highway link congestion may be resolved within several hours. Since port is part of the transportation network, any congestion/disruption is likely to ripple throughout the hinterland. In this sense, it is important to model properly the role nodal congestion plays in a context of spatial models and international trade. Thus, we have developed a spatial CGE model integrated to a transport network system in order to simulate the impacts of increases in port efficiency in a context of trade liberalization. The role of ports of entry and ports of exit are explicitly considered in order to grasp the holistic picture in an integrated interregional system.

Technology assessment of future intercity passenger transporation systems. Volume 1: Summary report

Technical, economic, environmental, and sociopolitical issues associated with future intercity transportation system options were assured. Technology assessment was used as a tool to assist in the identification of basic research and technology development tasks that should be undertaken. The emphasis was on domestic passenger transportation, but interfaces with freight and international transportation were considered
