Item Application of space time concept in GIS for visualizing and analyzing travel survey data(2006-05) Lu, Xiaoyun; Zhang, Ming, 1963 April 22-The classic time geography concept (space-time path) provides a powerful framework to study travel survey data which is an important source for travel behavior studies. Based on the space-time concept, this research will present a visualizing approach to analyze travel survey data. By inputting the data into GIS software such as TransCAD and ArcGIS and editing the needed information, this study will explain how to create 3D images of travel paths for showing the variation of trip distribution in relation to different social-economic factors deemed as the driving forces of such patterns. Also, this report will address the technical challenges involved in this kind of study and will discuss directions of future research.Item Bus stop attributes and perception of safety : case study Huston Tillotson University(2010-12) Gomez Sanchez, Ana Julita; McCray, Talia; Mueller, ElizabethThis professional report examines the degree to which the perception of safety shapes travel behavior in Austin, Texas, using Huston Tillotson University (HT) students as our case study. Focus groups are used to explore and identify what elements of the public transit experience are considered safe and unsafe. The report explores what “frightens” HT participants away from using the bus. A quantitative study is then used to measure environmental variables and their relation to bus stops and perceptions of safety. Austin crime data are used to locate bus stop crimes and develop a real context for bus riders’ perceptions of crime. After describing the conditions of bus stops based on physical, environmental, and criminal attributes, the study develops scenarios for the study areas. This report closes by summarizing the empirical findings and gives design and policy recommendations for transportation planners, agencies, and policy makers.Item Mixed land use and travel behavior : a case study for incorporating land use patterns into travel demand models(2014-05) Pang, Hao; Zhang, Ming, 1963 April 22-Metropolitan planning organizations (MPOs) have become increasingly interested in incorporating land use patterns and design ideas into transportation problems. Many design ideas under the umbrella of the New Urbanism; yet in practice they hardly get fully implemented in the standard transportation planning procedures. This research intends to contribute to the continuing debate on land use pattern-travel connection by adding further empirical evidence from the Austin, TX region. Also, it demonstrates ways to integrate land use patterns in transportation demand analysis. The study identifies 42 mixed use districts (MXD) in the Austin region and analyzes the following aspects of travel behavior in MXDs and non-MXDs: production trip rates, frequency of produced trips, network trip length, internal rate of capture, and person-miles of travel (PMT). The study contributes to transportation planning and policy making in Central Texas by providing local empirical evidence on urban form-travel connection. The study’s method and process can be of interest to a broad audience in academia and practice.
