METROPOLITAN WASHINGTON AREA TRANSIT SIGNAL PRIORITY PLANNING, DESIGN, AND IMPLEMENTATION — WASHINGTON, DC
CLIENT: WASHINGTON METROPOLITAN AREA TRANSIT AUTHORITY (WMATA) AND DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
This project involved planning, designing, and implementing a regional transit signal priority system in the metropolitan Washington, DC area. Planning from 2006 –2008 was for a regional concept of operations to collaborate with regional agency stakeholders on strategies and implementation needs. With funding from TIGER in 2010, a team provided technical assistance to WMATA and regional stakeholders to evaluate technologies and vendors for a large-scale procurement process. Leadership also used a multidisciplinary team to evaluate and design transit signal priority and intersection improvements across multiple corridors and more than 200 intersections. The team developed bid packages for the system procurement and installation, and assisted DDOT and WMATA through testing and acceptance. The regional transit signal priority system was implemented in 2016. It has continuous team guidance on a comprehensive performance evaluation and active system management.
District DOT and WMATA Bus Stop Improvement Design —Washington, DC
CLIENT: WASHINGTON METROPOLITAN AREA TRANSIT AUTHORITY (WMATA) AND DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
Bus stop improvements were planned and designed along three corridors at 12 locations in the District. More than 20 locations were initially evaluated, assessing construction feasibility and opportunities for improvements, such as pedestrian access, construction of a bus shelter, improved stop amenities, and pavement conditions. Construction plans included cost estimates and specifications. Bus stops were evaluated to determine potential for relocation from near-side to far-side or to modify on-street parking to accommodate additional buses at the stop. The project team collaborated with WMATA, DDOT parking, and traffic operations staff.
District DOT Traffic Safety Engineering Services On-Call — Washington, DC
CLIENT: DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
Work with the District Department of Transportation (DDOT) was done through the Traffic Safety Engineering Support Services On-Call Contract, contributing day-to-day support for traffic safety, traffic operations, transportation engineering, transportation planning, and transportation engineering design. The project consisted of more than 20 task orders to address safety needs across District neighborhoods and included senior oversight and quality assurance/quality control. Tasks included field data collection, traffic counts, and parking inventories to analyze speed mitigation treatments, pedestrian and bicycle improvements, safety countermeasures, traffic signal retiming, and intersection designs. Each aspect supported DDOT staff with technical analysis and public engagement.
District DDOT Streetcar Operations — Washington, DC
CLIENT: DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
Staff provided technical support to integrate a 2.2-mile streetcar system along the H St./Benning Rd. corridor in Washington, DC. One key task involved signal integration review and implementation for the corridor. The streetcar alignment varies between curbside and median, running through the corridor four times. Work with the rail control team effectively integrated train control with traffic signal control and programmed the traffic signal controller to provide dedicated signal phases. Managing the planning, assessment, and final design of traffic signal operations along the Anacostia Line were part of the project. Work also included planning for the preferred alignment through a series of signalized intersections and determining the necessary traffic signal modification and train control integration.
Portland Streetcar Operations — Portland, OR
CLIENT: CITY OF PORTLAND BUREAU OF TRANSPORTATION
Operational improvements were identified along the streetcar corridors to improve travel times and performance reliability. The team analyzed traffic and streetcar data to assess signal timing, lane utilization, stop activity, and ridership. Spot intersection and corridor improvements were identified for near-term and long-term plans according to funding opportunities. Improvements included stop consolidation, modifications to striping, future alignment adjustments, queue jumps, and priority signal timing.
DISTRICT DOT ADAPTIVE SIGNAL CONTROL PLANNING, DESIGN, AND IMPLEMENTATION — WASHINGTON, DC
CLIENT: DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
This project involved management to establish adaptive signal control technology along three DC corridors. The corridors are commuter routes; signal optimization was critical throughput peak hours. Signal timing was overseen for optimization of two of the corridors, as well as the systems engineering process and design and implementation of adaptive technology at roughly 50 intersections. Signal designs were prepared and feedback prioritized from stakeholders with DDOT. The team completed PS&E documents for upgraded equipment including detectors, controllers, and communications.
Arlington County Army Navy Dr. Traffic Study & Complete Street Redesign — Arlington County, VA
CLIENT: ARLINGTON COUNTY, VIRIGINIA
As part of an on-call contract with Arlington County, a multimodal transportation analysis was conducted of existing and future conditions. The purpose was to evaluate baseline no-build conditions and design alternatives for a complete streets project on Army Navy Dr. Multimodal alternatives were developed, including two-way protected bike lanes and exclusive transit lanes. The alternatives balanced local-level and system-level needs for all users while considering corridor and intersection capacities, user delays, and safety. The team also developed microsimulation models for select alternatives and identified the operational changes for each corridor configuration. Guidance and oversight were provided for analysis considerations and QA/QC.
Some projects featured here were conducted under a previous employer.
