In current practice, transportation planning often ignores the effects of major transportation improvements on land use and the distribution of land use activities, which might affect the accessibility impacts and economic efficiency of the transportation investment strategies. In this paper, we describe the model specification and application of the land use transport interaction model TIGRIS ...

The structure of transportation networks and the patterns of accessibility they give rise to are an important determinant of land prices, and hence urban spatial structure. While there is ample evidence on the cross-sectional relationship between location and land value (usually measured from the value of improved property), there is much less evidence available on the changes in this relations...

Accessibility is traditionally considered to be a property of a point or region in space, and to be invariant over time (or at least over some computationally convenient time interval). However, a location’s accessibility can vary over time on a wide range of scales. This temporal variation is especially significant for schedule-based transportation systems. Current integral measures of accessi...

Several different trends in the 1990s have led to increased efforts to improve the alternatives to driving. In response, planning agencies have been taking a new look at both transportation and land use policies in an effort to enhance transportation choices. Their efforts have been hampered by a lack of practical planning tools. What's needed are practical measures of accessibility that can be...

OBJECTIVE To analyze the difficulties in accessibility to health services experienced by persons with disabilities. METHODOLOGICAL PROCEDURES A qualitative study was performed with individuals who reported having a certain type of disability (paralysis or amputation of limbs; low vision, unilateral or total blindness; low hearing, unilateral or total deafness). A total of 25 individuals (14 w...

A methodology is developed in this paper for evaluating and enhancing the performance of urban transportation systems in the aftermath of a disaster. A performance measure is proposed for assessing overall and distributional impacts based on the concept of accessibility. The methodology is demonstrated with two case studies. The first focuses on passenger railroad disruption in the catastrophic...

In this research, the centers involved in relief operations in Tehran traffic area districts have been compared and the supply-demand ratio has been specified through a relation presented separately for each district. The supply has been evaluated based on three parameters: 1) No of relief centers, 2) congestion of the main road (the ratio of the length of the main road to the area of the distr...

This paper proposes a novel facility location model for health service network design by considering different key elements including the reliability aspects, service capacity, congestion, service quality, surrounding public infrastructures, geographical accessibility and several types of cost such as investment, transportation and operational costs. We formulate the problem as a robust scenari...

Efforts to improve transportation choices and enhance accessibility at the neighborhood level have been hampered by a lack of practical planning tools. This paper identifies the factors that contribute to accessibility at the neighborhood level and explores different ways that planners can evaluate neighborhood accessibility. A gap between the data needed to describe important accessibility fac...
