  • Abstract:
    The objective of this research is to develop a set of design and operational recommendations to reduce the number of rollover, jackknife, and rollback end positions for trucks entering the emergency ramp. To do so, the research team used several strategies including a review of literature, appraisal of incident reports, conduct field observations at several emergency escape ramps, interviews and surveys of the I-70 corridor stakeholders, perform an analysis of current geometry and material used in emergency ramps, and conduct interviews with other DOTs and CDOT staff about fuel or cargo spills. The study includes six main tasks as shown below, which form the structure of this report: Chapter 1. Introduction and Background Chapter 2. Field Observation Reports Chapter 3. Material and Design Analysis of the Arrester Bed Chapter 4. Interviews with I-70 Mountain Corridor Stakeholders Chapter 5. Ramp Performance Evaluation (Hazmat) Chapter 6. Conclusion and Recommendations Implementation The products of this research are a series of recommendations focusing on: a) maintenance/material replacement, b) signage and pavement marking, c) shoulder strengthening/widening, d) new construction, e) lighting, and f) drivers’ outreach. Specific recommendations to be implemented by CDOT include improved maintenance and entrance reconstruction of the arrester bed for the Lower Straight Creek Ramp, the new construction of a dragnet system and updating side road as asphalt for Vail ramps, improved signage and lighting at all ramps, and removing vegetation and improving clear zones for Upper Straight Creek Ramp. The goal of these recommendations is to keep the driver safe and the truck and trailer upright with minimal fuel spills or cargo loss. The implementation of these recommendations will benefit freight carriers through improved driver safety and freight security, the traveling public through fewer “runaway trucks”, and the general public through less hazardous material discharge into the natural environment.
