ItemActive 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. ItemCosts 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). ItemDELDOT Research Summary(Center for Applied Demography & Survey Research, 2023-09-25) Racca, David P.This research conducted numerous efforts to develop information resources that can support traffic and travel demand data collection, management, processing, integration, and presentation. ItemDemographic 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. ItemDevelopment and Evaluation of a Residential Allocation Model Using Time Series Tax Parcel Data in GIS(Center for Applied Demography & Survey Research, 2010-09) Racca, David P. ItemDevelopment of a Comprehensive, Multi-Modal Travel Accessibility Indexing System at the Tax Parcel Level(Center for Applied Demography & Survey Research, 2013-09) Racca, David P. ItemEconomic Aspects of ITS Improvements for Delaware: A Brief Review(Center for Applied Demography & Survey Research, 2011-08-23) Brown, Daniel T. ItemEstimating Accessibility to Destinations Offered By Transit(Center for Applied Demography & Survey Research, 2022-09-15) Racca, David P.There is an increasing need to examine transportation needs and services at the community level. General estimates of transit service such as, “within a quarter mile of a bus stop” do not capture trip characteristics with respect to where people want to go. Using the General Transit Feed Specification (GTFS), which captures the current transit schedules, stop to stop travel times were examined and mapped to describe service to local communities. ItemExamination of GIS and Current Infromation System Plans and Responsibilities(Center for Applied Demography & Survey Research, 2006-11) Racca, David P. ItemExamination of Streetlight Data(Center for Applied Demography & Survey Research, 2022-06-15) Racca, David P.Web based data analysis sites could have a very large impact on transportation planning and data development. Estimates can be performance data such as volumes and speeds, but also travel demand information since trip estimates going into and out of various land uses can be produced. Streetlight and products like it are very promising and could change the way we get transportation information. The big question is how close to reality estimates might be. An excellent application of the traffic and travel demand data compiled in this project is the evaluation of Streetlight data, where streetlight data can be compared to other measures. A first look at the Streetlight estimates is discussed below. ItemHazardous 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. ItemIntegration of Traffic and Travel Demand Data in Delaware(Center for Applied Demography & Survey Research, 2022-08-31) Racca, David P.Transportation performance measures from many sources are integrated using a set of road network and graphic elements locationally referenced to identifiers from standard linear referencing systems. Data from DelDOT Bluetooth sensors, NPMRDS, TMC devices, traffic counts, ATRs, intersection counts, and other data were compiled and integrated. In a similar way, the approach incorporates travel demand modeling estimates and relates them to measures. Such performance measures are always referenced to specific collection dates and times so it is critical for integration that the time dimension of measures and estimates be managed and consolidated. Efforts made to array measures through time of day and season are discussed. ItemAn Investigation of Routing Strategies To Improve Transit Service(Center for Applied Demography & Survey Research, 1998-07) Racca, David P. ItemJurisdictional Maintenance Project(Center for Applied Demography & Survey Research, 2002-03) Racca, David P.; Condliffe, SimonMaintenance 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. ItemPedestrian 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. ItemPresentation 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.
