Travel Behavior, Residential Preference, and Urban Design: A Multi-Disciplinary National Analysis

Greene, J
Larco, N

Rodriguez, D
McDonald, N
2011

This report summarizes the findings of a national project to examine the travel behavior, social capital, health, and lifestyle preferences of residents of neotraditional developments (NTD) compared to more standard suburban developments. We compare survey results from residents of matched pairs of neighborhoods in seventeen U.S. cities and towns, with each pair comprised of one NTD and one typical suburban neighborhood of similar size, age, and socio-demographic composition. The study addresses salient themes in the transportation, planning and health literatures: a national study,...

Can Information Promote Transportation-Friendly Location Decisions? A Simulation Experiment

Rodriguez, DA
Levine, J
Agrawal, AW
Song, J
2011
Where people live, work, shop, and recreate fundamentally determines their local travel options. Yet, information problems such as the cost of conducting comprehensive searches and cognitive load have been shown to limit decision-making. In the context of residential decision-making, information problems are likely to influence which locations get chosen. This study examines whether providing people seeking a rental home with map-based information about the transit and...

Household Excess Travel and Neighbourhood Characteristics: Associations and Trade-offs

Fan, Y
Khattak, A
Rodriguez, D
2010

This study proposes an alternative approach to estimate excess travel using activity diaries, extending it to non-work travel and capturing interhousehold variation. Central to this approach is a residential relocation exercise that helps to decompose the amount of travel by a household into two types of travel: required and excess travel. An empirical demonstration of the approach in North Carolina shows that on average 30 per cent of households’ travel in the study area is in excess. Furthermore, lower levels of required and excess travel are found among households living in...

Exploring Walking Differences by Socioeconomic Status Using a Spatial Agent-Based Model

Yang, Y
Roux, AV Diez
Auchincloss, AH
Rodriguez, DA
Brown, DG
2012

We use an exploratory agent-based model of adults' walking behavior within a city to examine the possible impact of interventions on socioeconomic differences in walking. Simulated results show that for persons of low socioeconomic status, increases in walking resulting from increases in their positive attitude towards walking may diminish over time if other features of the environment are not conducive to walking. Similarly, improving the safety level for the lower SES neighborhoods may be effective in increasing walking, however, the magnitude of its effectiveness varies by levels...

Ten Strategies for Freeway Congestion Mitigation with Advanced Technologies

Daganzo, Carlos F.
Laval, Jorge
Munoz, Juan Carlos
2002

This report presents ten strategies for improving freeway performance that have become feasible with the advent of new software and hardware technologies for traffic control. Most of the strategies can be applied with advanced implementations of existing hardware. The strategies have in common that they can be rigorously tested. heir measures of performance can be reliably obtained and do not depend on the accuracy of data- hungry, large-scale models.

Evaluation of the Anaheim Advanced Traffic Control System Field Operational Test: Executive Summary

McNally, M. G.
Moore, James E., II
MacCarley, C. Arthur
Jayakrishnan, R.
1999

This Executive Summary provides an overview of the technical and institutional issues associated with the evaluation of the federally-sponsored Anaheim Advanced Traffic Control System Field Operations Test. The primary FOT objective was the implementation and performance evaluation of adaptive traffic signal control technologies including an existing second generation approach, SCOOT, and a 1.5 generation control (1.5GC) approach under development. Also selected for implementation was a video traffic detection system (VTDS).The SCOOT evaluation was defined relative to existing, first...

The Influence Of Close-following Upon Cooling Module Air Flow

Browand, Fred
Marcu, Bogdan
Sharpe, Christian
1998

The purpose of this report is to experimentally determine the air flow through the cooling module (air-conditioning condenser plus engine radiator) of a Ford Windstar minivan when the van is operated at a fraction of a vehicle length behind a lead van. Pressures and temperatures are measured across the cooling module while the vans are in operation, and a standard calibration relates the pressure drop to the flow velocity through the cooling module. The Windstars are connected in tandem and driven on a test track at spacings of 0.22, 0.28, 0.38, 0.62, 0.88, and 1.0, expressed as fractions...

The Netcell Simulation Package: Technical Description

Cayford, Randall
Lin, Wei-Hua
Daganzo, Carlos F.
1997

This report describes the NETCELL simulation package. NETCELL is a freeway network simulation program based on the cell transmission model which captures the dynamic evolution of multicommodity traffic over a freeway network with three-legged junctions in a way that is consistent with the hydrodynamic theory of highway traffic. NETVIEW is a graphical postprocessor for viewing NETCELL output files. This document discusses implementation of the programs in detail, including the cell representation for a freeway network with three-legged junctions, data and file structures, inputs and outputs...

Carlink II: A Commuter Carsharing Pilot Program Final Report

2004

CarLink II was a commuter-based carsharing pilot project administered by the Institute ofTransportation Studies at the University of California, Davis (ITS-Davis) in conjunction with Caltrans, American Honda Motor Company, and Caltrain. Partners for Advanced Transit andHighways (PATH) researchers conducted the evaluation. Pilot objectives included testing an advanced carsharing system, understanding user response to this service, and testing its long-term sustainability. From July 1, 2001 to June 30, 2002, the CarLink II program was deployed in the field and continued the investigation of...

Stated And Reported Route Diversion Behavior: Implications On The Benefits Of ATIS

Khattak, Asad
Kanafani, Adib
Le Colletter, Emmanuel
1994

This report presents a study in which Advanced Traveler Information Systems (ATIS) user benefits are estimated from a survey of commuting behavior undertaken in the San Francisco Bay Area in 1993. Both reported and stated response to unexpected congestion are used to determine the commuters who would directly benefit from qualitative, quantitative and predictive, as well as prescriptive ATIS information
