Bicycle Facility Analysis and Design

SWA has evaluated over four dozen corridors for bicycle compatibility including signing, marking, exclusive lanes and cycle tracks.   Assessed impact to traffic operations, parking, roadway safety and overall network connectivity.  Developed wayfinding concepts and messaging.   Prepared preliminary and final design plans for a dozen corridors including signing, marking, signals and construction costs.

 

Traffic Calming Analysis and Design

SWA evaluated and developed concepts for over two dozen traffic calming locations including road diets, chokers, mini-roundabouts, mini-islands and ADA upgrades. Incorporated green treatments including bioswales, raingardens and porous pavers. Developed detailed design plans including signing, pavement marking, new geometry, landscaping, streetscaping, lighting and signals.  Performed analysis of traffic volumes, speeds, capacity and assisted the City with stakeholder and public outreach.

 

Neighborhood Parking Studies

SWA evaluated existing and future curbside and off-street parking supply, utilization, and demand, include development of a geodatabase and GIS mapping, and coordination with key institutional stakeholders and parking garage operators. Developed parking and transportation management recommendations including on-street parking regulatory and configuration changes, shared parking, wayfinding, parking guidance systems and demand/ event management.

 

Transit Operations and Planning

SWA performed a ridership survey and fare assessment to identify trip characteristics and rider demographics. Performed literature review and best practice assessment of urban circulator systems.  Reduced and geocoded over 1,500 completed surveys; developed a pivot table and evaluated findings.
