Showing papers in "Transportation Research Part A: General in 1989"

TL;DR: A model and a solution procedure efficient enough to handle real-world variants of simultaneous deliveries and pickups at the same node is developed and a case study dealing with a public library distribution system in Franklin County, Ohio indicates that substantial time/distance savings can be achieved.

TL;DR: In this article, an analysis of incidents using data from a major Los Angeles, California freeway is presented, and duration is analyzed as a function of incident characteristics, such as incident type, time of day, truck involvement, and lane closures.

TL;DR: Assessment of the driver visual attentional demand requirements of an operational in-car navigation system shows that the demand of most of the navigation tasks was comparable to that of one or more conventional tasks.

TL;DR: Analysis of 30-second data on flows, occupancies, and average speeds of freeway operations near bottlenecks caused by incidents suggests that the outline of an alternative logic, based on the catastrophe theory model of the flow-occupancy-speed pattern, is suggested for freeway incident detection.

TL;DR: In this paper, the authors examined the impact of overnight restrictions and time zones on the configuration of an air freight network and found that the location of a hub terminal impacts the arrival pattern of airplanes at the terminal.

TL;DR: In this article, the authors conduct an updated and detailed evaluation of the performance, costs, environmental impacts, and recharging requirements of electric vehicles and find that considerable progress has been made in EV battery and powertrain technology since the last surge of interest in EVs in the 1970s.

TL;DR: In this article, the sensitivity of fuel choice to fuel prices was investigated using data on purchases of regular, premium, leaded, and unleaded grades of gasoline for the years 1982, 1983, and 1984.

TL;DR: In this article, the authors examined the spread process of container technology at the Port of Belawan and its hinterland of North Sumatra, Indonesia, and focused on the important role of policy as a catalyst to the spatial penetration of this foreign imposed transport mode.

TL;DR: In this paper, a multinomial logit model of vehicle type choice is developed which more completely differentiates imports by country of origin, using a 1985 national sample of new car buyers to estimate the model, willingness to pay measures were calculated and nested hypothesis tests on attribute valuation performed.

TL;DR: In this paper, the authors reexamine the financing system and analyze the possible menus for fund-raising from the viewpoint of imbalance between benefit receivers and cost burdeners on the basis of benefit principle, referring to Japanese examples.

TL;DR: The demand for cars is rising in most parts of Southeast Asia, especially in the larger cities as mentioned in this paper, and the car is a major contributor to urban congestion which road building and traffic management measures cannot entirely alleviate.

TL;DR: The Urban Mass Transportation Administration's (UMTA's) transit analysis methods have relied on cost-effectiveness measures with little attention devoted to the analysis of economic efficiency as discussed by the authors, and there is widespread disagreement over the wisdom of building rail systems in American cities.

TL;DR: This paper details the experiences in applying a specific verification framework (based on traditional software engineering tenets) during a traffic engineering KBS development effort and provides useful insights to other researchers involved in traffic engineeringKBS development projects.

TL;DR: The fundamental relationships between cycle time and delay as well as number of stops of a signalized street link based on the simplification assumptions are shown together with the results of a field experiment.

TL;DR: A new information system using road/automobile communication to increase road-users' convenience is studied, which consists of a navigation system, a dynamic information system, and an individual communication system.

TL;DR: The transport models are reviewed under the main headings of aggregate forecasting procedures and both a history of the land-use models and its concepts are illustrated here, focusing on the allocation procedures of activities in modeling in Japan.

TL;DR: Based on the 1950 Comprehensive National Land Development Act, four consecutive Comprehensive National Development Plans have been formulated so far under the land planning framework, which is closely coordinated with the economic plan as discussed by the authors.

TL;DR: In this paper, the authors estimate the cost of these concessions: how much did transit management pay for the right to use part-time labor? It appears the cost was very large: during the early period of the innovation (1978-1981) the "give-backs" necessary to win labor consent were probably as large as, or larger than, the financial gains from use of parttime labor.

TL;DR: In this article, the Pioneer air and sea services which provide access to remote areas are examined and a complementary rationale for new directions in transport investment planning is examined, where the pursuit of the objectives of equity and income redistribution conflicts with efforts to improve the efficiency of investment alternatives.

TL;DR: In this paper, the authors examined the financial structure of individual motor carrier industry segments to determine whether deregulation brought about significant changes in that structure, using canonical correlation to identify interrelationships among asset variables and liability/equity measures both prior and subsequent to the Motor Carrier Act.

TL;DR: Tolling can complement general road user taxation (aimed at recovering costs on uncongested roads) where some degree of congestion exists, in order to achieve efficient pricing and rational resource allocation as discussed by the authors.

TL;DR: In this article, the authors focus on the control policies and countermeasures to prevent traffic pollution, and researches to enforce them, and propose an economic incentive policy, such as road pricing, that takes the place of conventional regulatory countermeasures.

TL;DR: In this paper, the effects of fuel switching in the vehicles operating on the dominant U.S. transportation modes are statistically tested using nineteenth and twentieth century data using logistic curve models fitted to often sparse data on fuel use.

TL;DR: In this paper, the authors consider some idealised networks and circulation systems that have simple geometrical configurations, and identify those systems that are relatively efficient in terms of path crossings, as compared with a theoretical yardstick derived from graph theory.

TL;DR: In this paper, the authors examined the reasons for a continued interest in government regulation, state ownership, and foreign involvement at a time when a contrasting set of policies advocated privatisation and self-reliance are being promoted in other sectors of Southeast Asian economies.

TL;DR: The research activities in individual choice modelling in Japan are summarized as follows: active research works have been carried out to improve the practicability, disaggregate approaches involve an ordinary statistical method such as a regression analysis, and the models have been practically applied in transportation planning fields.

TL;DR: In this paper, a rich variety of passenger transport modes other than ordinary buses and taxis in the cities of developing countries are discussed, and the advantages of free competition are fully demonstrated because of loose control.

TL;DR: In this paper, the authors proposed a system to determine the upper limit of cross-subsidization in cases where the construction of an unprofitable route is planned to attain the policy objectives and the need and scale of public subsidies are determined according to this.

TL;DR: The authors examines the present quality of public transport services in Budapest and compares that to the impact of growing car ownership and concludes that much of the proposed investment in a metro system will not maintain public transport's competitive position in the face of rising car ownership.

TL;DR: A number of states have placed high-speed rail service on their institutional agendas in recent years as discussed by the authors, and they have examined economic and political forces, as well as the transportation problem environment and established transportation commitments.
