  • Spill Clean-Up Recommendations for Emergency Escape Ramps (Eers): Western Mountain Dots’ Perspectives
    55th ASC Annual International Conference Proceedings Copyright 2019 by the Associated Schools of Construction Spill Clean-up Recommendations for Emergency Escape Ramps (EERs): Western Mountain DOTs’ Perspectives Deniz Besiktepe, Ph.D. Student¹, Dr. Rodolfo Valdes- Dr. Kelly Strong, Ph.D.² Vasquez, Ph.D.¹, and Dr. Scott Shuler, Ph.D.¹ ¹ Department of Construction Management, ² Department of Construction Management, Colorado State University University of Northern Iowa Fort Collins, Colorado Cedar Falls, Iowa Steep grades and runaway trucks have the potential of severe and fatal crashes. The use of an emergency escape ramp (EER) accommodates the control of runaway trucks by slowing and stopping them. Fuel or hazardous material (hazmat) spills may result from rollover or jack knife after trucks enter the EER. The objective of this research is to understand the clean-up processes and the remediation techniques after trucks enter ramps, and the auditing/verification processes after the clean-up. Additionally, this study presents a set of recommendations to improve spill clean-up processes and remediation techniques after trucks enter EERs. The recommendations are developed by using the combined method of literature review, phone interviews with staff from western state Departments of Transportations (DOTs), emergency responder companies, and hazmat personnel from Colorado DOT unit as well as exploratory analysis. The implementation of the recommendations will benefit DOTs and freight carriers through improved driver safety and freight security, and the general public through less hazmat discharge into the natural environment. Key Words: Emergency escape ramp, Truck escape ramp, Runaway truck ramp, Fuel spills, Clean- up, Maintenance. Introduction Emergency Escape Ramps (EERs) have proven to be an effective method to control and stop runaway vehicles by transferring the vehicles’ energy through gravitational deceleration, rolling resistance or both (Abdelwahab, & Morral, 1997).

While modern building designs follow specific regulations to provide safe accessibility to wheelchairs, many older neighborhoods still contain designs inaccessible and dangerous for people in wheelchairs. For example, many ramp designs have slopes too large or lengths too short to safely stop a rolling wheelchair. Therefore, students are challenged to design accessible ramps using common rocks and minerals to modify ramp surfaces that can safely and efficiently stop wheelchairs. In completing the design challenge, students will demonstrate understanding of mathematical relationships between speed and motion and differentiation of potential and kinetic energy. By maintaining an Engineering Log, students will also develop skills in writing quantitative ideas and evidence-based argument.

  • HPR-280: a Review of Truck Escape Ramps
    A REVIEW OF TRUCK ESCAPE RAMPS for HPR-PL-1(31)280 EVALUATION OF ARRESTER BED PERFORMANCE Steven 1. Tritsch, P.E. Senior Research Engineer Arizona Department of Transportation Arizona Transportation Research Center 206 Smth 17th Avenue Mail Drop 075R Phoenix, Arizona 85937 December 1987 INTRODUCTION DESIGN HJSTORICAL EXPERIENCE CURRENT RESEARCH CONCLUSIONS AND RECOMMENDATIONS REFERENCES ANNOTATED BIBLIOGRAPHY . - . .. TRUCK ESCAPE RAMPS INTRODUCTION Truck escape ramps, for the purposes of this review, are designed by highway engineers to safely slow down and stop a runaway vehicle. The typical runaway vehicle may be a loaded tractor trailer unit speeding down a long hill with overheated brakes and no way to stop under its own power. The vehicle ultimately reaches a velocity where curves can no longer be negotiated and crashes - into an ern5ankment, a ravine, or another vehicle. Truck escape ramps have been used in this country for over 30 years. There are currently over 65 escape ramps in use throughout the United States today. Of the three types (gravity ramps, sandpiles, gravel beds) of escape ramps, the gravel bed is the most predominant design used today. The aggregate used in the gravel bed has been referred to as "pea" gravel, which has many connotations, depending on the agency or part of the country one is in. DESIGN The design of escape ramps has evolved from a trial and error process. At the present time, there are no nationally accepted design standards for truck escape ramps. Several states have departmental policies and/or guidelines for designing escape ramps in their jurisdictional boundaries. There are numerous articles and publications on the subject; however, many tack the supporting documentation necessary to justify an overall design methodology for universal use.

  • From Truck-Only Lanes
    Appendix A. NCHRP Project 03-73 Separation of Vehicles – CMV- Only Lanes Task 7 – Interim Report NCHRP Project 3-73: Separation of Vehicles - CMV-Only Lanes A. NCHRP Project 03-73 Separation of Vehicles – CMV-Only Lanes Task 7 – Interim Report A.1 Introduction This interim report document provides results of the first phase of research on National Cooperative Highway Research Program (NCHRP) Project 03-73 Separation of Vehicles – Commercial Motor Vehicle-Only Lanes project. It presents a review and discussion of a wide range of issues relevant to planning, designing, and evaluating a variety of concepts from CMV-Only Lanes that should be useful to planners and policy makers in the public and private sector. It also presents an evaluation of available data and its suitability to conduct additional analyses in Phase II of the research plan. A.1.1 Project Overview For a number of years, there has been growing interest in commercial motor vehicle (CMV)- only lanes and several notable proposals for CMV-only lane systems/projects have appeared in the planning and traffic engineering literature. To a large extent, this growth in interest has been related to the growth in truck traffic relative to automobile traffic and the contribution of truck traffic to congestion. Heavy trucks have a greater impact on capacity than their sheer volume would suggest, especially when mixed with automobiles. Separation of autos and trucks may be a beneficial way of building more system capacity in certain circumstances. A number of studies also have suggested that CMV-only lanes that are tolled may present a viable means of financing system capacity improvements.

In fact, because of the enormous area we have tried to cover, we can guarantee that we have probably missed some passes and steep grades that deserve to be included. We have not attempted to cover unpaved roads since large vehicles usually stay on the main paved roads. Sometimes the percentages quoted are estimates and many times they are based on road signs or information provided by highway departments.

  • From Footpaths to Freeways
    From Footpaths to Freeways A Survey of Roads and Highways in Minnesota By Joel Katz, P.E., PTOE Minnesota Department of Transportation DEDICATION This book is dedicated to the thousands of Minnesotans — past and present — who have been involved in the planning, design, construction, maintenance, and operation of the roads, streets, and highways of Minnesota, , as well as those who have played essential roles in such areas as financing, administration, research, education, and communications. These are the people who have been employed by the federal, state, and local governments; contractors; consultant firms; and educational institutions who have applied their professional and trade experience in developing a transportation system on which our way of life and economic viability has become so greatly dependent. Some of these employees lost their lives while performing construction, maintenance, and enforcement activities. All have worked diligently, loyally, and professionally — especially in emergency situations.

  • New Jersey Statewide Transportation Improvement Program
    New Jersey Statewide Transportation Improvement Program Fiscal Years 2007 - 2010 Governor Jon Corzine Commissioner Kris Kolluri, Esq. October 1, 2006 Table of Contents Section IA Introduction Section IB Financial Tables Section II NJDOT Project Descriptions Section III NJ TRANSIT Project Descriptions Section IV Authorities, Project Descriptions Section V Transition Projects Section VI Glossary Appendix A FY 2006 Major Project Status Appendix B FY 2007-08 Study & Development Program SECTION IA INTRODUCTION Introduction a. Overview This document is the Statewide Transportation Improvement Program for the state of New Jersey for federal fiscal years 2007 (beginning October 1, 2006) through 2010. The Statewide Transportation Improvement Program (STIP) serves two purposes. First, it presents a comprehensive, one-volume guide to major transportation improvements planned in the state of New Jersey therefore providing a valuable reference for implementing agencies (such as the New Jersey Department of Transportation and the New Jersey Transit Corporation) and all those interested in transportation issues in this state. Second, it serves as the reference document required under federal regulations (23 CFR 450.216) for use by the Federal Highway Administration and the Federal Transit Administration in approving the expenditure of federal funds for transportation projects in New Jersey. Federal legislation requires that each state develop one multimodal Statewide Transportation Improvement Program (STIP) for all areas of the state. In New Jersey, the STIP consists of a listing of statewide line items and programs, as well as the regional Transportation Improvement Program (TIP) projects, all of which were developed by the three Metropolitan Planning Organizations (MPOs). The TIPs contain local and state highway projects, statewide line items and programs, as well as public transit projects.
