    Identifying and illustrating urban traffic congestion, mobility, and accessibility using a Gis

    Full text link
    Urban congestion, accessibility, and mobility are important concerns affecting the quality of life in metropolitan areas. It is important that accessibility and mobility should not be compromised while developing strategies to alleviate congestion. The effects of traffic congestion include not only increase travel delays, which result in the increase of travel times, but also impacts energy consumption and air quality. All of these have detrimental effects on the quality of life. In order to develop strategies to alleviate urban congestion, it is necessary to first identify where and when congestion occurs--i.e., the spatial and temporal distribution of congestion. The objective of this research is to demonstrate the application of a geographic information system (GIS) to help identify and illustrate urban congestion, accessibility, and mobility. Definitions of mobility, accessibility, and congestion are presented as well as the advantages of using a GIS. A list of performance measures which are typically used to quantify these transportation functions are discussed. Data required to quantify the performance measures, their sources and integration within a GIS are discussed. Lastly GIS analyses used to quantify the performance measure are discussed. The performance measures used are: (1) non-recurring delay, (2) average vehicle occupancy, (3) business and employee accessibility to transit routes, (4) residential accessibility to transit routes, (5) Transit accessibility to areas of low automobile ownership, and finally (6) travel time. Specific example are presented to illustrate the application of GIS to evaluate the performance measures identified. In turn, these can be used to develop policies and operational strategies to address congestion (and potential congestion), mobility, and accessibility issues in urban areas. Conclusions are the GIS is a viable tool to assist planners and engineers to identify problem areas using already existing data sources

    Creating a Resilient Transportation Network in Skagit County: Using Flood Studies to Inform Transportation Asset Management

    This report presents the results of a Climate Resilience Pilot Project conducted by Washington State Department of Transportation (WSDOT) and sponsored in part by the Federal Highway Administration (FHWA). WSDOT received a grant from FHWA to develop options for improving the resiliency of transportation facilities or systems to climate changes and/or extreme weather events. The pilot project set out to meet FHWA\u2019s goal of helping further the state of the practice in applying vulnerability assessment results into decision making. This study builds on WSDOT's earlier pilot by examining adaptation options in an area of the state we previously identified as highly vulnerable: the Skagit River Basin (Basin). WSDOT chose this Basin because it is the focus of a major flood study by the U.S. Army Corps of Engineers (Corps). WSDOT knew important decisions about how and where to invest in levees and other flood risk reduction projects were being actively evaluated by the Corps and the local sponsor, Skagit County. WSDOT also knew that state transportation assets were likely to be affected but were not the focus of their study. WSDOT\u2019s pilot presented the opportunity to actively engage with the flood study and search for compatible long-term solutions that create a more resilient transportation system throughout the Basin. WSDOT\u2019s pilot shows transportation planners and asset managers how to leverage a federal flood study, like the Corps\u2019 Skagit River Flood Risk Management General Investigation Study (GI study), to improve the resiliency of our highways. The pilot demonstrates how WSDOT\u2019s Vulnerability Assessment results, used in combination with federal flood study data, can reaffirm known vulnerabilities and reveal other vulnerable assets. The pilot identifies adaptation strategies for the Basin and highlights future partnership opportunities with the Corps and local governments. This report includes a series of recommendations and lessons learned that will help other DOTs and regional transportation planning entities reach across jurisdictions and sectors to create integrated asset management strategies

    Designing and implementing injury surveillance systems in Indian country : instructor's guide

    Get PDF
    This manual, the presentation and the materials provided are meant to be a core for a course on designing and implementing injury surveillance systems in Indian Country. Whenever possible you should use your own experience and draw on examples from the local community. Be sure to include the class in providing examples when possible. There are many examples of successful surveillance efforts in Indian Country in Appendix 1 of this manual. Please read and become familiar with them as they can also help illustrate many of the key points in this course.This manual is your guide to the course. Each chapter provides instructor notes, a copy of the presentation with notes and a copy of the corresponding chapter in the participant manual annotated for the instructor. The PPT presentation notes reference a page number within the text of the manual where the points on the slide are discussed. As already stated, the Appendix of this manual includes many examples of surveillance work that is being done in Indian Country, but you should feel free to supplement it with your own examples and/or examples that would be more familiar to the class.A joint publication of the National Center for Injury Prevention and Control, part of the Centers for Disease Control and Prevention, and the Indian Health Service Injury Prevention Program.Publication date from document properties.Complete%20Instructor%20Manual%20-%205-28-2013.pd
