Traffic Works 2018 Summit!

The staff at Traffic Works took a day off from the office and went on a team-building snowshoeing adventure up to Incline Peak in Tahoe! The climb from the base to the peak took approximately three hours and an additional two hours to get back to the bottom. The sight on top of Incline Peak overlooked Lake Tahoe and was absolutely stunning! Traffic Works looks forward to take advantage of the outdoors and team-building exercises to create a positive workplace atmosphere.

Oroville SR 162 Pedestrian/Bicyclist/Disabled Mobility and Safety Improvements

Building off of our recently completed work for the City of Oroville to create the SR 162 Corridor Plan, Traffic Works provided added value to its client by preparing a winning implementation project funding application to the Caltrans statewide Active Transportation Program (ATP). The proposed project, now being recommended by ATP staff for nearly $3.5 Million in State funding, will retrofit and enhance the State’s right-of-way to make it function less like a congested, urban arterial roadway and more like a pedestrian and bicyclist-friendly “Main Street”. To the relief of all involved, Traffic Works consulted strategically with City staff, project stakeholders and the regional MPO sponser (BCAG) to make the project visioning and information-gathering as pain-free as possible, and independently produced the application content in the required ATP format. Having successfully justified the requested funding to transform Oro Dam Boulevard and Olive Highway, the two important thoroughfares comprising SR 162 in the heart of Oroville will undergo the following “active” (non-motorized) transportation connectivity and safety enhancements:

  • Closing 11 sidewalk, 7 street lighting, and 4 bike lane gaps
  • 1 multi-use trail connection
  • 1 mid-block crosswalk enhancement
  • 9 pedestrian/disabled barrier-free ramps at existing intersections
  • 40 crosswalk upgrades at 10 corridor signalized intersections
  • 4 new crosswalks and 2 pedestrian-activated hybrid (“H.A.W.K.”) crossing signal

Traffic Works is a proud sponsor of RTC FREE Safe Rides this Saint Patrick's Day in Reno!


Drunk driving is one of the most unacceptable, yet overlooked, behaviors in the modern era. NDOT reports that there have been a total of 5 alcohol related traffic fatalities since February 26, 2016. In an effort to reduce the number of alcohol related fatalities and injuries on Nevada’s roads, RTC Washoe will offer free transit service on Saint Patrick’s Day, March 17th, from 4pm to midnight on all regularly scheduled transit services through the FREE Safe Ride Program.  Additionally, the downtown circulator bus, SIERRA SPIRIT, will have extended hours. This is the 13th year of the FREE Safe Ride Program and Traffic Works is proud to be a sponsor of this great event.  The program encourages safe driving and reminds the public to never drive impaired.

Caltrans Issues Separated Bikeway Design Guidelines

As a final act of 2015, the California Department of Transportation (Caltrans) Division of Design issued guidelines for Separated Bikeways/Cycle Tracks (Design Information Bulletin #89).  These guidelines will help cities and agencies throughout California begin to develop networks of elite bikeways which help to encourage new cyclists to ride.  Separated Bikeways, also called Cycle Tracks or Dutch Intersections, have been used extensively in European countries for decades and are held up by bicycle advocates as the best design to ensure safety for cyclists and through that safety, encourage new riders to begin to cycle.  While this form of bicycle infrastructure has existed across the pond for many years, this design concept is just beginning to take hold in the United States.  In 2015, the first protected intersection in the US was constructed in Davis, CA and was followed closely by the construction of the second protected intersection in Salt Lake City, UT.  Austin, TX gained their first protected intersection as part of a new development and Boston, MA has plans to construct a protected intersection on Commonwealth Avenue.

This design concept makes bicycling and walking safer at intersections and creates a more attractive bicycling environment for new riders.  With this design getting the green light from Caltrans and other agencies, it will surely begin to appear in more and more cities across the country.

4th & Prater BRT Project Wins FTA Award for Planning Excellence!

Last week the Federal Transit Administration released the biennial Transportation Planning Excellence Awards for 2015 and included among the projects was the 4th Street / Prater Way Bus RAPID Transit Project.  Among many other partners, Traffic Works has been involved in this project since 2012 and is currently working on the final signal designs for the project.  We were proud to be part of such an outstanding team and are honored to have had the chance to participate in such an important and influential project for the Reno-Sparks area.  This project will help connect downtown Reno with Sparks through enhanced zero-emission bus rapid transit service, accessible sidewalks, and bike lanes. In addition to improving transit service and bicycle connectivity, the 4th & Prater BRT project is expected to spur economic development in a part of town where 59 percent of households are below $20,000.  This project was funded through a Federal TIGER grant of $16 million and will begin construction in 2016.
