This report investigates the role that public transit can play in reducing traffic congestion. Investigates the role that public transit can play in reducing traffic congestion. This analysis indicates that high quality public transit tends to reduce congestion by attracting travelers who would otherwise drive. As public transit service improves on a corridor (including improved speed, convenie...

The system optimal routing problem has been widely studied for road network while it is less considered for public transit system. Traditional shortest-path-based multimodal itinerary guidance systems may deteriorate the system performance when the assigned lines become congested. For this issue, we formulate the dynamic system optimal routing model for multimodal transit system. The transit sy...

This paper presents a model that calculates the social welfare benefits of using additional subsidy to reduce fare levels or improve service levels of public transit in Chicago. The model differentiates between the effects in peak and off-peak periods for both bus and rapid rail service. The potential welfare benefits of transit improvements accrue to several different groups of people: (1) exi...

BACKGROUND Most public transit users walk to and from transit. We analyzed the relationship between transit commuting and objectively measured physical activity. METHODS Adults aged 20 to 65 working outside the home (n = 1237) were randomly selected from neighborhoods in Seattle and Baltimore regions. Neighborhoods had high or low median income and high or low mean walkability. Mean daily min...

Inadequate transportation has emerged as a major bamer to employment for welfare reelplents required to tranmtlon from pubhc assistance to employment under welfare reform. Transportatmn is a particularly daunting barrier for single women without access to a household car This study uses multivariate techmques to examine whether nearby transit access impacts the emplobanent outcomes of th~s popu...

Public transit is an important tool for those looking to ease their commutes, reduce their car dependence, or perhaps minimize their environmental impact. Unfortunately, the usability of transit systems often leaves much to be desired, to the point of deterring new riders. Tools on the web and mobile devices are increasingly being used to help tame confusing transit systems. OneBusAway is one s...

Opioid overdose is a growing public health emergency in the United States. The antidote naloxone must be administered rapidly after opioid overdose to prevent death. Bystander or "take-home" naloxone programs distribute naloxone to opioid users and other community members to increase naloxone availability at the time of overdose. However, data describing the natural history of take-home naloxon...

This paper shows a scheme of urban transport management aimed at solving the externalities due to road trac. In this scheme both private and public transport modes are managed by a planning authority having control of some decision variables: road pricing, transit ticket prices, and the service characteristics of transit. The multimodal transport system is subject to some constraints: physical...

The passage of welfare reform renewed a long-standing debate over whether improved public transit would significantly lessen the length of time that people remain on welfare. Language of the act reflects an assumption that it would. On the other hand, the automobile provides such a high level of service and is so widely available even to the poor that it is difficult to comprehend how improved ...
