Targeted Safety Improvement
Transportation programs encompass many projects and activities that are executed with a plan under which the projects/activities advance a purpose or goal. Transportation programs are on-going, they are part of the 6-Year Transportation Improvement Program (6-Year TIP) and they support the Transportation Master Plan (TMP).

Motor vehicle traffic collisions have more far-reaching effects than just on those individuals who are directly involved. The economic consequences to society as a whole can equal tens of billions of dollars in lost productivity, medical costs, and personal problems such as substance abuse or depression that can follow serious crash-related injuries.

The mission of the City of Redmond's Targeted Safety Improvement Program is to identify existing and potential traffic safety problem areas and implement projects to reduce crashes, injuries, deaths, and their related losses through pro-active collision prevention, reactive collision response, and multi-modal safety consistent with the TMP.

Program Description
Underline Image

The Targeted Safety Improvement Program (TSIP) carries out the policy direction in the TMP, and is an item in the 3-Year Priority Action Plan. The key elements of the program help to identify existing and potential traffic safety problem areas and implement projects to reduce traffic collisions using proactive and reactive strategies. TSIP uses a systematic method to clearly identify, evaluate, and recommend safety projects that will be of benefit to the Redmond community.

Project Selection
Underline Image

Projects considered for TSIP funding come from several sources:

  • High accident locations identified through the City's Collision Reporting System
  • Traffic requests recorded in the traffic request database that is managed in Public Works/Transportation Services
  • Requests made via the City's Traffic Safety Committee
  • Unfunded or underfunded 6-Year TIP project
  • Unfunded or underfunded Neighborhood Traffic Calming Program projects
  • City staff-identified traffic safety needs based on future land development
Once the list of potential projects is assembled, each project is ranked individually using a matrix to evaluate risk (assigns values to the level of severity of the collision and the likelihood of its reoccurrence) and project complexity/cost (assigns values to how complex a project is to complete and to dollar ranges of cost to implement).
 
On May 24, 2011, staff updated the City Council on TSIP projects, and asked for direction on projects proposed for the 2011-2012 biennium.  A copy of the memo to the City Council is posted for review.

The following are TSIP activities for 2009 and 2010. If you click on the link at each program activity, you will find a map for that area.

Funds for 2009: $450,000

Program activities in 2009:

Leary Way at West Lake Sammamish Parkway/SR 520 Bike Trail Crossing
Underline Image

Issue: Frequent conflicts between right-turning vehicles from southbound West Lake Sammamish Parkway to the westbound SR 520 on-ramp and pedestrians and bicycles crossing West Lake Sammamish Parkway to enter or exit the SR 520 Bike Trail or use the Sammamish River Trail.

Solution: Add "Vehicles Must Stop for Bikes and Pedestrians" signage, modify the traffic signal as required, and relocate the crosswalk for slightly improved visibility.
Intended Outcome: Better visibility and signage for drivers, pedestrians, and bicyclists.

Status: Currently under construction. Expected completion in the fall of 2010.

Citywide Traffic Signal Head and Streetlight Visibility
Underline Image

Issue: The visibility of traffic signal indications at many of the City's 100 signalized intersections is compromised by low hanging tree limbs and vegetation. This is a substantial project beyond the scope of normal traffic operations, requiring a large maintenance contract to bring the City into reasonable compliance. Once this project is complete, routine annual maintenance can be provided by City traffic operations and street staff.

Solution: Hire contractor for significant removal of trees, branches, or other vegetation.
Intended Outcome: Obstructions to traffic signal displays are eliminated.

Status: Project is complete. Future trimming is now within the maintenance program budget.

Willow Road Puget Sound Energy Trail Crossing
Underline Image

Issue: The Puget Sound Energy pedestrian trail is not aligned on either side of Willows Road. Pedestrians and cyclists must cross the road at an unprotected midblock location. Willows Road has relatively high traffic volumes and speed. The entrance to Overlake Christian Church is adjacent to the trail connection on the east side of Willows Road.

Solution
: Realign the trail on each side of Willows Road. Install a traffic signal to accommodate a safer crossing for trail users. Coordinate the design of the crossing location and signal with Overlake Christian Church.

Intended Outcome: Safer crossing for pedestrians and cyclists.

Status: Construction is planned for fall 2010.

Funds for 2010: $450,000

Countdown Pedestrian Signals
Underline Image

Issue: An unfunded Federal mandate requires cities to upgrade all pedestrian signal heads at crosswalks to countdown pedestrian signals where crossing time is more than seven seconds. This needs to be complete by December 2013.

Solution
: Change pedestrian signal heads at approximately 90 intersections around the City.

Intended Outcome: Equipment will bring City into compliance and inform pedestrians of the number of seconds remaining to cross the road.

Status: Installation to begin in August 2010 with completion expected at year's end.

Old Redmond Road and West Lake Sammamish Way
Underline Image

Issue: Intersection needs to be realigned and a traffic signal needs to be constructed.

Solution
: Realign intersection and install traffic signal.

Intended Outcome: Better visibility and improved safety.

Status: Under construction.

Avondale Road Corridor Study
Underline Image

Issue: Improving traffic flow along the corridor as well as circulation for all modes of travel and connectivity to neighborhoods off of Avondale Road is needed. The Greater Southeast Redmond Area Transportation Study identified locations needing further design to address access management and u-turns on Avondale Road. Safety and operational issues relative to transit pedestrian movements and access have been reported through citizen complaints.

Solution
: Evaluate, prioritize, and design improvements for these safety, access, and mobility issues.

Intended Outcome: A prioritized plan for delivering safety, access, and mobility improvements for the corridor.

Status: Preliminary design to begin in early fall of 2010.
