In response to a successful TIGER grant award of $27 million to the MTA, Wilson T. Ballard and Sabra & Associates, Inc. (SAI), was tasked to complete a comprehensive redesign of North Avenue from Hilton Street to Milton Street. The goal of the project is to improve multimodal operations including transit service, transit reliability, provide bicycle facilities and lanes, as well as enhance the overall public realm to support economic development throughout the corridor.
Multi-modal Transportation Planning: Corridor traffic and transit operations analysis to evaluation various alternatives to re-purpose general purpose travel lanes to dedicated bus lanes, and bike lanes, and on-street parking alternatives. The work included analysis of traffic and transit big data sets including bus sec-by-sec position, speed, passenger load data to identify key delay points in bus stops, and the arterial network; analysis of Level of Service and delays for the vehicular network, and analysis of bicycle network alternatives. SAI prepared conceptual plans and cost of preferred alternatives. Our team prepared public meeting displays, and attended multiple public meetings and coordinated with multiple public and private stakeholders.
Engineering Design: SAI was responsible for the traffic engineering, ITS, Lighting and Maintenance of Traffic Design. The lighting was complex due to the high luminance values required for nighttime safety lighting in the areas of the bus stops while needing to provide uniformity along the corridor. SAI prepared bid ready plans, specification and estimates for this project on an aggressive schedule to meet the TIGER funding requirements.
Transit Signal Priority: The TIGER grant required early implementation of bus network improvements via TSP, prior to the roadway rehabilitation. SAI provide turn-key services for TSP from initial planning through the hands-on construction of the system for Phase 1 and Phase 2. The Phase 1 work consisted of Passive TSP and included set-up and configuration of the central traffic signal system; swap-out, programming and configuration of new traffic signal controllers at 44 intersections; and development of signal timing plans to provide Passive TSP. The Phase 1 project was completed on-time and a full two years prior to the start of construction to meet the federal requirements. SAI is currently working on Phase 2 (Active TSP) and the work included preparing contract documents for ordering TSP cabinet equipment. SAI will field implement and configure this TSP equipment.
