Safe Main Street Highways (SMSH) – year 3 (2014-2015)

PI: Anne Vernez Moudon (UW)
Dates: 01/15/2015 – 06/15/2016

Increases in non-motorized travel also raise important safety issues, as pedestrians and bicyclists constitute the most vulnerable road users. Therefore, tools to identify locations with a high risk of collisions between motor-vehicles and pedestrians or bicyclists are essential to insure that gains in mobility, air quality, and health are not accompanied by higher rates of injuries and fatalities in vulnerable road users.

An Evaluation of Safety Impacts of Seattle’s Commercial Delivery Parking Pricing Project – year 3 (2014-2015)

PI: Anne Goodchild (UW)
Co-Investigators: Edward McCormack (UW)
Dates: 01/15/2015 – 06/15/2016

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.

Relationships among Worker Gender, Communication Patterns, and Safety Performance in Work Zones – year 3 (2014-2015)

PI: Jessica Kaminsky (UW)
Dates: 01/15/2015 – 06/15/2016

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 – year 2 (2013-14)

PI: Philip Hurvitz (UW)
Dates: 9/30/13 – 7/31/2015

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 – year 2 (2013-14)

PI: Donald Janssen (UW)
Dates: 9/16/13 – 2/15/2015

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.
