The overall goal of the staff of the Southern California Association of Governments (SCAG) is to develop specific, quantifiable, and easily understandable performance indicators for the region’s transportation system that better inform elected officials and policy boards of the broad array of choices for investing public and private funds. SCAG’s performance indicators are intended to capture the important relationships between transportation and a diversity of public policy concerns. The seven performance indicators used in the preparation of the 1997 Regional Transportation Plan (RTP) are mobility, accessibility, environment, cost-effectiveness, reliability, safety, and customer satisfaction. SCAG applies these performance indicators to each of its 13 subregions and to the region as a whole. The federal Intermodal Surface Transportation Efficiency Act of 1991 and Clean Air Act Amendments of 1990, and SCAG’s 1994 Regional Mobility Element, set the stage for the abandonment of the old and popular level of service measure. SCAG’s performance indicators approach the concept of performance from the perspective of the users of the transportation system, in contrast to traditional approaches that focused more on facilities and vehicles. SCAG is currently at approximately the midpoint in the development of the 1997 RTP and therefore has considerable practice in working with the performance indicators. This experience confirms the value of performance indicators as a planning tool.

Purpose This paper aims to understand the trade transportation situation between China and Koreas, and to explore the possibility of establishing the surface transportation corridor between China and Koreas in the future. Moreover, the paper also intends to find out the mode choice behaviors of shippers, which can be used to analyze the substitute effects of the surface modes on the water one. Design/methodology/approach The paper first analyzes the Sino-Korean bilateral trade and the corresponding trade transportation between China and Koreas. Secondly, it presents the surface transportation network between China and Koreas, and analyzes the warming relations between the North and South. Finally, the modal split of trade transportation between China and Koreas is estimated by establishing a mode choice model based on a questionnaire survey. Findings With the increasingly stable political environment and the physical highway and railway connections, the surface transportation network would become possible. Moreover, the shippers need the multimodal transportation system between China and Koreas, and many shippers would select road or rail mode if a suitable road or rail network were available. Especially, between China and South Korea, the road, rail and water mode may be used evenly, while the road mode may play a more important role between China and North Korea. The surface modes would have a huge substitute effect on the water mode. Originality/value The existing literature conducted research mainly from the perspective of economy and geopolitics, while the topics of transportation between China and Koreas are rarely concerned. This paper intends to throw some light on the situation of the trade transportation between China and Koreas, consider the potential of relation improvement on the Korean Peninsula proactively and study the surface transportation issues between China and Koreas.

In December 1993 Secretary of Transportation Federico Peña called for the creation of a National Transportation System (NTS). The goal of the NTS is to support national transportation planning and policy that maximize the efficiency and effectiveness of the nation's transportation network, in accordance with the mission of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). It is proposed that the U.S. Department of Transportation (DOT) pursue this goal by designing an NTS that can monitor the performance of the nation's transportation network; detect national and regional problems with the transportation system; facilitate the setting of performance goals and measure progress over time; and aid states and metropolitan areas in performance-based planning. To do this, the NTS must evaluate the transportation network's performance in terms of moving passengers and goods and of achieving the goals of the system's users. Therefore, the NTS must have as its basis a set of performance measures that apply to different modes and that reflect the varied goals of ISTEA, in the areas of system output as well as the environmental, social, and economic outcomes of system usage. Such performance measures are proposed, as is a general decision-making framework for using them. The ISTEA legislation, the NTS initiative, and potential data sources for supporting these performance measures are also examined.

The 1990s may well be remembered as the decade in which the idea of sustainability took hold in government, business, academia, and popular culture. In the United States, concerns with sustainability have entered policy discussions at various levels of government and sectors of the economy. The application of the sustainability paradigm to transportation has coincided with the advent of intelligent transportation systems (ITS). ITS—the application of advanced technologies (e.g., computers, communications, advanced sensors) to the surface transportation system—is a major new advanced transportation technology initiative that has become a highly touted prospect for improving the nation’s surface transportation system. ITS could have significant effects on the nation’s environment, economy, and society, and this has prompted widespread research and speculation on the range of potential ITS impacts. It has also brought ITS into the sustainability debate, and controversy exists over whether ITS will facilitate or undermine efforts to promote sustainable communities. A series of conceptual and applied exercises being done at the national level, as well as within Minnesota, on the implications of the sustainability paradigm on ITS are described. After the policy context surrounding ITS is introduced, key dimensions of the sustainability concept, particularly sustainable development and sustainable communities, are examined. The concept of sustainable communities is linked to transportation and ITS. In conclusion, findings on how ITS and other information technologies might promote sustainable communities are given, with special attention to the context of Minnesota’s ITS program.

Quantification Model

Large-scale natural disasters challenge the resilience of the surface transportation system. The objective of this research was to develop a resilience model of the surface transportation system with a mixed-traffic environment and considering varying Connected and Automated Vehicle (CAV) penetration scenarios. As deployment of CAVs is expected to improve traffic operations, a resilience model was developed in this research to evaluate the resilience performance of a transportation system with several CAV penetration levels (0%, 25%, 50%, 75%, and 100%) for a given budget and recovery time. The proposed resilience quantification model was applied on a roadway network considering several disaster scenarios. The network capacity in relation to trips at any phase of disaster was compared with the pre-disaster trips to determine the system resilience. The capacity variation and the travel time variation were also estimated. The analysis showed that the resilience of the transportation system improved with CAVs in relation to travel time and capacity improvement. Link travel times were significantly improved by higher CAV penetration rate. The findings also suggested that higher penetration of CAVs (i.e., 50% or more) increased the recovery costs. For example, the recovery costs needed for medium and large-scale disasters were 50% and 90% higher, respectively, compared with the recovery costs for a small-scale disaster. These higher costs were primarily for the repair and replacement of intelligent infrastructure required to support the operation of CAVs.
