This paper discusses the spectrum acquisition activities that are underway in North America and the spectrum management activities that are occurring in the regulatory agencies that affect intelligent transportation system (ITS) spectrum acquisition. It includes a discussion of the specific spectrum requirements needed to support the 29 User Services that have been adopted by FHWA and ITS AMERICA, and outlines a strategy for meeting those needs through a balanced approach that includes maximum use of existing communications networks as well as the acquisition of new spectrum for critical safety, warning and control functions.

A new landside complex, that includes new roadways, an airport light rail system, and a ground transportation center, is being planned to meet the expansion needs of San Francisco International Airport (SFIA). Existing terminals are served by roadways that cannot be expanded without significant investment and disruption. Therefore, SFIA has developed the concept of a remote ground transportation center-connected to departure terminals by the airport light rail system-to remove courtesy shuttle and scheduled transit traffic from terminal roadways. The SFIA design team developed a computer simulation model to quantify the demand and performance of each element of the new landside complex, as well as the performance of the landside complex as a system. This presentation reviews the modeling approach, demonstrates the simulation animation, and discusses the way the design team used data from the simulation model to refine the landside complex concept.

The authors describe how all parties in the Puget Sound advanced traffic management system implementation project evaluation process recognized the need for collaboration at the outset in educating one another of the interests of transit operations and urban traffic control. This collaboration continued through formal recognition of a multi agency, multidisciplinary proposal selection board to develop the system configuration and request for proposals details ans specifications, as well as participate in proposal evaluations and recommendations. It was to the benefit of all parties that the up front planning time and dedicated consensus building was necessary for successful implementation and regional acceptance of the system.

Guideway transit systems have seen a renaissance as they have captured the interest of the public, passengers, and decision makers as important infrastructure investments necessary to meet America's growing transportation needs. These systems have proven effective in serving high volume, established transit markets, but are increasingly proposed as a key element of intermodal systems to meet transportation needs in lower density, rapidly growing areas. Providing intermodal connections between airports and seaports, bus and rail systems, as well as public and private transportation is an important element in a comprehensive transportation system. Several factors including economic constraints, environmental concerns, and political and neighborhood concerns have constrained the pace of roadway expansion and resulted in the roadway system and existing transit services being unable to provide the quality or quantity of transportation services the citizens desire. All of these factors support the need for new, advanced, and effective mass transit systems which ride on their own guideways as part of the solution to urban transportation problems. This paper addresses the issues to be considered by urban areas whose search for transportation solutions include fixed guideway transit systems.

Two of the most essential features of the Michigan DIRECT (Driver Information Radio Utilising Experimental Communication Technologies) operational field test are simplicity of design and low cost to the motorist. The test has a focus on the in-vehicle receivers for real time driver information and with relatively limited in-vehicle processing. Additionally, there is no infrastructure expansion cost, as the existing ATMS equipment is proposed to be used for the test. The primary goal of the project is to evaluate the user benefits, institutional issues and technical issues of enroute driver advisory and traveler information services in an operational setting. The emphasis is on the testing and evaluation of voice-based communication systems that can offer: (a) basic services at a minimal incremental cost to the traveler; and (b) a high potential for operational deployment.

The authors describe the E1 series of Shinkansen electric trains, the first Shinkansen rolling stock to have all-double deck passenger cars. Passengers who cannot find seats in current cars must stand in the aisle. The purpose of developing E1 is to have more seats for commuters who are the railway's largest market. VVVF (variable voltage variable frequency) control was adopted, using the latest compact and lightweight equipment, which is placed at floor level at the end of each car to maximize the size of the passenger section.

Transportation in the next century will have to be much more flexible and convenient than today's systems in order to handle the volume of people and cargo that is projected. In order to improve our transportation system in a cost effective way we will need innovative means of tying our existing systems together and making each one more efficient. Historically, air transportation has been handled as an independent system with little thought given to access to other major modes other than automobiles. As a result we have created a very inefficient and time consuming air network which cannot be easily integrated with other systems, unlike the Europeans and Japanese who have integrated their systems very well. Tiltrotor technology gives us the opportunity to develop intermodal facilities, called vertiports, which can easily tie all transportation modes together in convenient locations with a minimum amount of land and relatively small costs. Vertiports can be an inexpensive means of providing communities with improved air transportation while reducing air and ground congestion that is becoming a major problem to all travelers.

The paper focuses on the fact that navigable digital street maps are one of the critical success factors for vehicle navigation systems and information systems. For a long time data have formed the main bottle-neck in the development and market introduction of these systems as a successful mass market application in Europe. This paper describes how this bottle-neck is solved and how it has eventually led to the realization of a European standard and availability of a uniform digital street map.

The authors describe how, using available World Bank assistance, the Kingdom Of Thailand's Department Of Highways (DOH), part of the Ministry Of Transport and Communications, engaged consultants in late 1993, to prepare a long-term strategic highway plan for the Kingdom. This is the first time that a long-range perspective was applied to the planning of the nation's highway system. The technique will enable DOH to better plan its road development and to be more consistently responsive to the demographic and social changes taking place throughout the Kingdom. The five-year planning period previously used resulted in plans that were relatively inflexible and sometimes led to dramatic shifts of emphasis in response to plan changes in other sectors, or as a result of major midterm revisions of the plans.

The increase of the average transport distances and number of trips, the decrease of equipment productivity and the specialisation of services and vehicles are the most important repercussions of the current economic context on the goods transport industry. Dispatch is highly affected by those constraints in so far as it realizes the "goods-drivers-trucks-trips" allocation. The dispatch strategy has direct repercussions on the profitability of the company. In fact, if the dispatch strategy is supply-oriented and aimed to increase equipment productivity, the company will be limited by its own capacities and resources. On the other hand, if the strategy is demand-oriented with regard to satisfy the maximum of it, the company must strive to find resources in order to satisfy its immediate needs. Therefore, which strategy would be the best with regard to the new economic context? The authors present a strategic approach for dispatch as one which can contribute significant competitive advantages to goods haulage companies. They also propose dispatch strategies which can be implemented by these companies in order to better manage operating costs and service differentiation.
