Few studies have examined the relationship between micro-scale features of the built environment and street segment usage. Micro-scale features of the built environment include the width of the sidewalk, the presence of amenities such as benches and trash bins, and the presence of crossing aids such as stoplights and crosswalks. This study employs segment-level primary data collected for 338 street segments in close proximity to one of 71 bus rapid transit stations in Bogotá, Colombia. We also use secondary data to control for area-level characteristics such as density, socio-...

The Full Cost of Intercity Transportation - A Comparison of High Speed Rail, Air And Highway Transportation in California

Levinson, David
Gillen, David
Kanafani, Adib
Mathieu, Jean-michel
1996

The Full Cost of Intercity Transportation Page ES-1 This study evaluates the full cost of three modes of intercity transportation: air, highway, and high speed rail. The evaluation is done within the context of the California Corridor, connecting the Los Angeles Basin and the San Francisco Bay Area. The purpose of evaluating full cost is to compare the economic implications of investment in, or expansion of, any of these three modes. The scope of the analysis is full transportation cost. Full transportation costs includes external, or social cost, in addition to the internal costs of...

Evaluating the Impact of ITS on Personalized Public Transit

Dessouky, Maged M.
Aldaihani, Majid
Shah, Rutvij
2002

The focus of this project is to study alternative system architectures and ITS technologies that can improve the efficiency of personalized public transit and demand responsive systems such as paratransit. This report reviews available and emerging ITS technologies that have been deployed or are being considered for this industry. We also conducted a survey of commercially available computer aided dispatching software. We list the numerous features offered by these software packages. Also, included in this report is a statistical analysis of travel patterns of a paratransit provider in Los...

Stated and Reported Diversion to Public Transportation in Response to Congestion: Implications on the Benefits of Multimodal ATIS

Khattak, Asad
Le Colletter, Emmanuel
1994

The objective of this study is to evaluate the potential benefits of a multimodal Advanced Traveler Information System (ATIS). The propensity of auto commuters to switch to public transportation in response to unexpected traffic congestion is investigated using a detailed survey undertaken in the Golden Gate Bridge corridor in 1993. A stated preference analysis tied to the situation for which the commuting behavior was reported is used to estimate the propensity of travelers to divert to transit under a multimodal ATIS.

This document summarizes the efforts by the San Francisco Bay Area ICM team to develop the concept of operation, data needs and performance requirements for an Integrated Corridor management System for I-880 Corridor. Although the transportation management systems at the Bay Area are consistent with the regional ITS plans, these management systems are less integrated. It is believed that higher lebel of intergration among freeway and arterial systems, transit systems with consideration of all transportation needs demands in the region will greatly enhance and improve the efficiency and...

Lateral Control of Commuter Buses

Hingwe, Pushkar
Tomizuka, Masayoshi
1995

This report presents two approaches to the design of the lateral controllers for commuter buses based on Sliding Mode Control (SMC). The objective of the control is to track the lane centerline. The first controller uses the sensor output which is a combination of yaw and lateral error. The second controller achieves tracking objective by providing a yaw rate to the vehicle so as to keep the lateral error dynamics stable. The two controllers are compared by performing simulations for a range of parameters.

ITS Information and Services to Enhance the Mobility of Disabled Travelers

Chen, Wan-hui
Uwaine, Rochelle
Klaver, Kelley
Kurani, Ken
Jovanis, Paul P.
1998

This study examined the potential of advanced information systems to increase the mobility of disabled travelers using public transportation. A stated preference survey inquired as to whether subjects would make more trips by transit, paratransit, and/or real-time paratransit if kiosk, on-board, in-home, and/or personal information systems were available. The results show that these systems do have the potential to increase the use of public transportation by disabled travelers, as they allow for more trip flexibility that what is currently available. Regression and log-linear models show...

Improving Transit Performance with Advanced Public Transportation System Technologies

Hansen, Mark
Qureshi, Mohammad
Rydzewski, Daniel
1994

This report identifies opportunities to improve transit performance using Advanced Public Transportation System (APTS) Technologies, assesses transit operator viewpoints on and experiences with APTS technologies, and proposes how current adoption and utilization practices might be improved so that these technologies are used in a more efficient and effective manner. The study focuses on the attitudes and experiences of individual transit agency management, staff, and line personnel that are likely to determine their future choices with regard to APTS adoption and utilization. The research...

Evaluation of the Advanced Operating System of the Ann Arbor Transportation Authority: Passenger Reactions to Transit Safety Measures

Wallace, RR
Rodriguez, D
White, C
Levine, J
1999
Safety and security are important considerations for the transit operator, but few empirical studies exist that measure the effectiveness of measures taken to improve transit safety on either actual crime (or other incident) data or transit passengers’ perceived safety. The current study focuses on the links between transit safety measures implemented in the Ann Arbor, Michigan region, the visibility of these improvements to transit passengers, and perceived ...
