District DOT Transit Signal Priority Planning, Design, and Implementation — Washington, DC
CLIENT: DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
This project encompassed the planning, design, and implementation of a regional transit signal priority system in the metropolitan Washington area. The project began with planning efforts in 2006-2008 for a regional concept of operations working collaboratively with regional agency stakeholders on operational 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 involved a multidisciplinary team to evaluate and design transit signal priority and intersection improvements across multiple corridors and at over 200 intersections. The team developed bid packages for the system procurement and installation and assisted DDOT and WMATA through testing and acceptance. The system was implemented in 2016 with continued team guidance for a comprehensive performance evaluation and active system management.
District Mobility — Washington, DC
CLIENT: DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
This DC Multimodal Congestion Management Study assessed, quantified, and communicated the state of congestion for multimodal transportation users in the District. Data requirements were researched and refined to allow for annual and scalable analytics to produce multimodal performance measures consistently across the entire District. The multimodal performance measures identified throughout the study are available at districtmobility.org and help communicate transportation investments that improve the transportation network.
Metropolitan Washington Council of Governments Bus Lane Enforcement Study — Washington, DC
CLIENT: METROPOLITAN WASHINGTON COUNCIL OF GOVERNMENTS
A framework was developed for the Washington regional agencies to plan, design, and operate effective bus lanes. The team conducted an international scan on bus lane implementations identifying successes and lessons learned. A guidebook for the regional agencies was produced to use in future bus lane implementations. The guidebook included enforcement strategies, design alternatives, educational strategies, and potential legislative actions.
ORIL: Bike Routes on Ohio Local System — Ohio
CLIENT: OHIO DEPARTMENT OF TRANSPORTATION (ODOT)
In collaboration with The Ohio State University, the team conducted a scan of current practices to develop and apply scalable methodologies leveraging existing roadway network data sets, analyzing methodologies to identify and assess roadway networks for bicycle facilities within Ohio. The desire was to identify a preferred methodology that all types of agencies within Ohio may utilize to identify, characterize, and assess bicycle facilities and relative levels of traffic stress. Once a model was developed, agencies would be able to manipulate mapping data to plan future investments effectively and strategically.
District DOT and WMATA Bus Stop Improvement Design —Washington, DC
CLIENT: WASHINGTON METROPOLITAN AREA TRANSIT AUTHORITY (WMATA) AND DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
Planning and design of bus stop improvements along three corridors at 12 locations was conducted. Over 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. Design plans were developed for construction including cost estimates and specifications. Bus stops were evaluated to determine the 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 coordinated 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. Responsible for senior oversight and quality assurance/quality control, the project consisted of over 20 task orders addressing safety needs across District neighborhoods. Tasks included field data collection, traffic counts, and parking inventories to analyze for speed mitigation treatments, pedestrian and bicycle improvements, safety countermeasures, traffic signal retiming, and intersection designs. Each task supported DDOT staff with technical analysis and public engagement.
DDOT Streetcar Operations — Washington, DC
CLIENT: DISTRICT DEPARTMENT OF TRANSPORTATION (DDOT)
Leading a technical team to integrate a 2.2-mile streetcar system along the H St./Benning Rd. corridor in Washington, DC, one of the key tasks involved signal integration review and implementation for the corridor. The streetcar alignment changes 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. Planning, assessment, and final design of traffic signal operations along the Anacostia Line were managed as part of the project as well as 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. Traffic and streetcar data were analyzed 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.
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 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.
City of Portland ITS Project and Planning — Portland, OR
CLIENT: CITY OF PORTLAND BUREAU OF TRANSPORTATION
This collaboration with the City of Portland Bureau of Transportation updated the Intelligent Transportation Systems (ITS) projects in the City Transportation System Plan. The project included integration with partners to develop descriptions and cost estimates for proposed projects used to develop a draft of the BUILD grant proposal.
Clark County Asset Management System — Clark County, WA
CLIENT: CLARK COUNTY, WASHINGTON
Leadership was provided for a systems engineering process with the Clark County staff to identify system and technical requirements for an asset management system for Clark County’s ITS and signals system. Deliverables included needs assessment and vendor technology evaluations.
City of Fort Lauderdale Traffic Signal Management — Fort Lauderdale, FL
CLIENT: CITY OF FORT LAUDERDALE, FLORIDA
Assessment of the City of Fort Lauderdale traffic signal system identified opportunities for managing, operating, and owning the signal system infrastructure. Included in the assessment were opportunities to expand ITS equipment and technologies to meet the diverse operational needs within the City including transit, freight, pedestrian and bicycles, and commuters.
Some projects featured here were conducted under a previous employer.
