Truck Parking: An Emerging Safety Hazard to Highway Users

Project Coordinator:
 Josh Roll
Research Agency:
 Oregon State University
Principal Investigator:
 Sal Hernandez
Start Date for ODOT:
 August 18, 2015
Completion Date for ODOT:

Research Agency:
 Portland State University
Principal Investigator:
 Liming Wang/Jennifer Dill
Start Date for ODOT:
 October 1, 2015

Use of Additional Lighting for Traffic Control and Speed Reduction in Work Zones

Project Coordinator:
 Jon Lazarus
Research Agency:
 Oregon State University
Principal Investigator:
 John Gambatese
Start Date for ODOT:

Principal Investigator:
 Jason Ideker/Karl Haapala
Start Date for ODOT:
 October 26, 2015
Completion Date for ODOT:

Binder-Grade Bumping and High Binder Content to Improve Performance of RAP-RAS Mixtures

Project Coordinator:
 Norris Shippen
Research Agency:
 Oregon State University
Principal Investigator:
 Erdem Coleri
Start Date for ODOT:
 November 16, 2015
Completion Date for ODOT:

OVERVIEW:

General reduction in pavement program funding levels over the past decade and the possible consequent increase in pavement road roughness within the next couple years creates a need for low cost yet effective alternative ways to rehabilitate, preserve, and maintain roadway network in Oregon. Mechanistic-empirical (ME) pavement design methods and laboratory testing need to be combined with different modeling methods to investigate the performance benefits of using binder-grade bumping and high binder content in Recycled asphalt pavement (RAP) and Recycled asphalt shingle (RAS) mixtures.

Assessing Highway System Impacts on Total Maximum Daily Load (TMDL) Watersheds Uning the Stochastic Empirical Loading and Dilution Model (SELDM)
 
Project Coordinator:
 Kira Glover-Cutter
Research Agency:
 USGS
Principal Investigator:
 John Risley
Start Date for ODOT:
 July 1, 2016
Completion Date for ODOT:
 July 31, 2017
 
Overview:
 
This project will develop and demonstrate techniques for geographic analysis that use the roadway and land use/land cover information in Streamstats to apply SELDM at selected points in the watershed. These techniques will include manual and batch-processing techniques that can be used to help model contributions of flows, concentrations and loads of stormwater from highway sites and other upstream land uses.
 
It will demonstrate methods for using SELDM with statistics on the quantity and quality of runoff from highways and other land uses and BMP treatment statistics to model the cumulative effects of runoff from different areas at different points in a stream basin.
 
The project will create guidance for watershed-scale analyses using SELDM that are based on results and experience learned in the second objective and document this information in at least one report.
