An Evaluation of Safety Impacts of Seattle’s Commercial Delivery Parking Pricing Project

Co-Investigators: Edward McCormack (UW)
Dates: 01/16/2015 – 06/15/2016
Status: Completed

Final Technical Report
The City of Seattle Department of Transportation (SDOT) conducts the Commercial Vehicle Pricing Project in order to improve commercial vehicle load zone access and efficiency in downtown Seattle and more, yet the project does not provide an understanding of the extent to which commercial vehicles circle while looking for available load zones or use parking areas outside of designated load zones. The proposed study will identify the correlations between collision rates and commercial vehicle on-street parking activity. In doing so, it will inform SDOTs revised strategies for Commercial Vehicle Load Zone location, pricing, and design, supporting the design of a safe and commercially accessible urban core. Read More
Relationships among Worker Gender, Communication Patterns, and Safety Performance in Work Zones

Final Technical Report
Safety communication, including safety training, is an important and cost effective tool for achieving excellent safety performance during construction (Hallowell 2010). However, recent work has identified that worker demographics has an impact on how safety knowledge is shared. Thus, the proposed research intends to study how worker gender impacts patterns of work crew safety communication on roadway construction in the Pacific Northwest. This project hypothesizes that work crews with both male and female members (or, gender diverse work crews) show different communication patterns and worse safety performance than crews without gender diversity and investigate this hypothesis by various methods in the project.

Smartphone-Based System for Automated Detection of Walking
PI: Philip Hurvitz (UW), phurvitz@u.washington.edu
Dates: 9/30/13 – 7/31/2015
Final Project Report: PacTrans-51-UW-Hurvitz
Walking is the most effective mode of travel to access transit: transit hubs with higher residential and employment densities have higher ridership levels because they serve areas where a large population is within a short walk of transit service. Walking has additional benefits: it is well-known as a low impact mode of travel for short trips to and from, as well as within, commercial areas; and it is the most popular form of physical activity. However, current data on walking are notoriously poor. Read More
Field Validation of Recycled Concrete Fines Usage
PI: Donald Janssen (UW), d6423@uw.edu
Dates: 9/16/13 – 8/31/2015
Final Project Report: PacTrans-32-UW-Janssen
A system for quantifying waste fines in a ready-mix concrete plant’s waste-water recirculation system will be designed, fabricated, and installed at the Stoneway Readymix Concrete Plant (in the Seattle area). Concrete mixtures produced at this plant will then be evaluated to document the effects of the waste fines optimization procedures.
Testing of Cavity Attenuation Phase Shift Technology For Siting Near-Road NO2 Monitors
PI: Tim Larson (UW), tlarson@uw.edu
Dates: 9/1/13 – 8/31/2015
Final Project Report: PacTrans-53-UW-Larson
Recent research has identified the public health importance of air pollution exposures near busy roadways. As a result, the Environmental Protection Agency (EPA) significantly revised its Nitric oxide (NO2) air quality standard in 2010. The current regulatory focus has shifted from assessment of longer-term (annual average) NO2 concentrations measured at locations away from busy roads to shorter-term (1-hour average) concentrations measured at locations near busy roads. Even though EPA has developed extensive guidelines for siting traditional air quality monitors that are located relatively far from roads, their siting guidance for near-road NO2 monitors is not yet officially established. Therefore this project proposes to test a more direct approach to siting near-road NO2 sampling locations using a state-of-the-art NO2 monitor that is no more expensive than traditional EPA chemiluminesce-base monitors, is much more readily deployed on a mobile platform, and can ultimately be used as the regulatory monitor at the official sampling location.
