This collection provides technical reports that analyze, among other things, factors which influence the need and distribution of transportation services, costs and benefits of advanced public transportation systems, travel demand, limitations of regression-based trip generation models, and routing strategies to improve transit service. The reports in this collection also examine maintenance costs and budgets together with the condition of transportation facilities and level of service provided. Others report aggregated data about individuals and the trips they make, the costs and benefits of travel modes, as well as identify actual speeds and travel times on Delaware’s roads. This collection provides valuable performance measures that can be used for transportation operations and planning.

    Active Adult (55+) Community Trip Generation Rates
    (2006-07-18T19:30:03Z) Racca, David P.
    In response to the growing number of applications for the development of age restricted communities (55 years old and older) the Delaware Department of Transportation (DelDOT) through the Delaware Center for Transportation sponsored this study to examine trip generation characteristics and traffic impacts.

    Costs and Benefits of Advanced Public Transportation Systems at DART First State
    (Center for Applied Demography & Survey Research, 2004-07) Racca, David P.
    This project focuses on an evaluation of Automated Vehicle Locator (AVL), dispatching and routing software and hardware systems, security systems and related technologies that have been recently (May 2001) implemented at DART First State. These technologies are addressed and evaluated nationally under the category of Advanced Public Transportation Systems (APTS).

    Demographic and Commuting Trends in Delaware
    (Center for Applied Demography & Survey Research, 1996-12) Ratledge, Edward C.; Racca, David P.
    There are many factors which influence the need and distribution of transportation services, but few are more important than the population base that uses those services. In this report, several population-related issues are addressed. These include population growth, the components of that growth, the impact and structure of migration, the way the population is organized in households, and finally, aspects of the age structure of the population.

    Hazardous Material Transportation Study: Phase I
    (Center for Applied Demography & Survey Research, 2002-12) Racca, David P.
    Previous hazardous material flow studies were studied and a number of local and national incident databases were examined in this project to assist in identifying the appropriate focus of future efforts to address the movement of hazardous materials. Goals of the project were to summarize what is currently known about HazMat, examine risks, and identify areas of most concern. Information has been summarized and presented in this report.

    Jurisdictional Maintenance Project
    (Center for Applied Demography & Survey Research, 2002-03) Racca, David P.; Condliffe, Simon
    Maintenance costs and budgets must be examined together with the condition of transportation facilities and level of service provided. Insufficient or no maintenance can lead to large capital replacement costs and shortened life span for facilities and that is not cost effective over several years. Not performing core maintenance and preservation also can lead to an inefficient, complaint based mode of reactive operation. To this end, this project addressed maintenance activities on transportation facilities involved with cleaning, patching, resurfacing, vegetation control, curbs, drainage, beautification, bridges, sidewalks, signals, lights, signs, snow plowing, structural adjustment, and signal and light energy usage to better understand the maintenance costs associated with such capital improvements.

    Pedestrian and Bicycle Safety Analysis
    (Center for Applied Demography & Survey Research, 2019-11) Racca, David P.
    In research sponsored by the Delaware Center for Transportation and DelDOT, traffic crashes involving injuries to pedestrian or bicyclists between the years of 2012 and 2016 were studied. Tabulations and maps of related factors were produced and reviewed as a starting point and are discussed here and in the body of the report. Data that could be useful to determine pedestrian and bicyclist activity levels were investigated so as to better understand the number of accidents that occur, the relative safety of current locations, the level of interaction between pedestrians, cyclists, and motor vehicles, and what might be appropriate safety measures. Approaches to estimating risk and exposure, and pedestrian activity were researched and available data for Delaware was investigated and related to observed crashes. This report includes numerous maps as an approach to isolating hot spots that could lead to mitigation projects. For instance in the City of Wilmington there are a few street blocks that have more crashes. Mapping can also show where crashes are occurring at a lower rate than expected, and in such areas, further investigation may provide some insight for safety initiatives.

    Presentation of Travel Demand and Relationships to Land Use
    (Center for Applied Demography & Survey Research, 2001-02) Racca, David P.
    Travel demand is often discussed in terms of current and future housing development in Delaware. With the expected increased congestion and costs associated with new development in Delaware, there is increasing interest in the relationship of land use and transportation and the promotion of land use policies that can address the effects of ever increasing travel demand. To address these issues, this study investigate the relationship between land use and transportation within the State of Delaware.

    (Center for Applied Demography & Survey Research, 1999-12) Racca, David P.
    This report discusses the status of information systems in the State of Delaware Department of Transportation (DelDOT) Division of Planning, examines issues concerning better access and usability of information, and poses initiatives for near term improvement. Centralized versus distributed systems, operational versus informational uses of information, advances in information technology, standards, and data integration are topics that are discussed in relation to possible solutions.

    Project Report for "Factors That Affect and/or Can Alter Mode Choice"
    (Center for Applied Demography & Survey Research, 2004-03) Racca, David P.; Ratledge, Edward C.
    This project uses data about individuals, their characteristics, the trips they make, and the costs and benefits of travel modes, to identify factors that can be used in models for travel mode choice. For use in travel demand forecasting and examination of transit markets, almost all mode choice models are developed using aggregate level data, typically at the level of a traffic zone, such as population totals, mean incomes, average household characteristics, and other summary data. Perhaps the reason for this is that aggregate data is typically more available such as provided by the U.S. Census data. These aggregate models, though they may be useful and have some predictive value for a given area, do not address the choices of individuals or develop a fundamental understanding of travel mode choice as may be indicated by the many conflicting results seen in the literature concerning factors that influence mode choice. This project addresses mode choice using data about individuals.
