Event-based ATIS: Practical Implementation and Evaluation of Optimized Strategies

Jayakrishnan, R.
Tsai, Wei K.

Adler, Jeffrey
2001

This project further adapt and enhance the previous research of relevance to event-based Advanced Traveler Information Systems (ATIS) and implement the algorithms for traffic management in Anaheim. This study is also answering some basic questions in ATIS implementation associated with routing strategies, driver’s compliance and network performance. This research develops algorithms for static and dynamic optimal Changeable Message Signs (CMS). The optimized CMS schemes are based on performance evaluations using a traffic simulation-based evaluation model, DYNASMART (Dynamic Network...

Evaluation Of The Advanced Operating System Of The Ann Arbor Transportation Authority: Impacts of an Advanced Public Transportation System: Demonstration Project

Levine, J

Hug, GE
Rodriguez, D
1999
In 1997, the Ann Arbor (Michigan) Transportation Authority began deploying a set of integrated advanced public transportation system technologies in its vehicles, stations and control center. This paper summarizes selected findings of a multidimensional evaluation of the effects of the system on schedule adherence and transfer time, passenger perception and impacts on drivers. Some improvement in on-time performance was observed in vehicle departures from major ...

How Chaos Does Not Destroy Ridership: Operations of an Exclusive Busway Carrying More Than 35,000 Passengers Per Hour Per Direction

Ardila, A
Rodriguez, DA
2000

Busways have been reported to carry up to 28,000 passengers per hour per direction (pphpd). However, recent passenger counts indicate that the exclusive busway in Bogotá, Colombia, has a flow of more than 35,000 pphpd. This passenger flow is achieved despite poor operating conditions and a general lack of maintenance without a city busway management and operation authority. Consequently, there is little police control, no systems management, and scarce information for users. These conditions should affect passenger flow negatively, but the Bogotá busway carries more passengers than...

Unwanted Excess Commuting: Proximate Commuting, Transportation Demand Management and the Transportation-Land Use Connection

Rodriguez, DA
2000

O f current theoretical controversies in urban pianning, arguably few have fartherreaching implications for policy than the debate on the relationship between transportation and land use. On the one hand, the transportation-land use relationship or connection focuses on the influence of transportation policy, including transportation services, infrastructure, and pricing, on individual and firm location decisions in a metropolitan area. On the other hand, the connection also encompasses the influence of individual and firm location decisions on transportation policy.

Proximate Commuting: Hype or Potential? An Evaluation

Rodriguez, DA
2001

Proximate commuting is a potential employer-based travel-demand management program under which large, decentralized employers reassign each voluntary participant to a job location (with the same employer) closer to the participant’s residence to reduce commuting distances. Key to determining proximate commuting’s feasibility and potential success are the identification and estimation of its commuting benefits. A model for quantifying the distance and time savings of proximate-commuting programs is presented. It relies on stated preference information regarding an employee’s...

Development of Pedestrian & Bicycle Transportation Course Modules.

Rodriguez, D

Sundstrom, C
Sandt, L
2014
According to a 2012 report by the Alliance for Biking and Walking, crashes involving bicyclists and/or pedestrians account for almost 15% of all traffic crashes. The states that house STRIDE consortium universities, including Florida, Alabama, Georgia, North Carolina, and Mississippi, are among the top seven states with the highest pedestrian and bicyclist fatality rates in the nation. Training the next generation of planners and engineers to consider pedestrian and ...

Davis Smart Mobility Model Project: Initial Scoping and Planning Study

Shaheen, Susan A.
Finson, Rachel S.
2003

The goal of the Davis Smart Mobility Model project is to optimize individual mobility options through improved connectivity among modes, enhanced techniques to link land-use planning and transportation system design, advanced information technologies, and clean-fuel vehicles. The California PATH/Caltrans partnership with the University of California, Davis (UC Davis) started when campus planners expressed interest in learning how innovative mobility services and technologies (such as carsharing and smart parking management) might help to alleviate the transportation impacts of a campus...

Bicycle Safety in Bogotá: A Seven-Year Analysis of Bicyclists’ Collisions and Fatalities

Carvajal, G

2020
Road safety research in low- and middle-income countries is limited, even though ninety percent of global road traffic fatalities are concentrated in these locations. In Colombia, road traffic injuries are the second leading source of mortality by external causes and constitute a significant public health concern in the city of Bogotá. Bogotá is among the top 10 most bike-friendly cities in the world. However, bicyclists are one of the most vulnerable road-users in the city. Therefore, assessing the pattern of mortality and understanding the variables affecting the outcome of bicyclists’...

Promoting Active Community Environments Through Land Use and Transportation Planning

To examine the role of land use and transportation plans as policy instruments for promoting active community environments. Cross-sectional analysis using multilevel models to examine whether active community environment scores were associated with leisure and transportation-related physical activity (PA) and whether associations varied by household income. 67 North Carolina counties Adults (n = 6694) from pooled 2000 and 2002 North Carolina Behavioral Risk Factor Surveillance System (BRFSS)...
