INTRODUCTION This document describes a project that extends New York City’s existing Sub-regional Architecture (NYCSRA). The New York City Sub-region consists of the geographic area encompassing New York City’s boroughs of Manhattan, The Bronx, Brooklyn, Queens, and Staten Island. These five boroughs (i.e. counties) are at the center of the New York – New Jersey – Connecticut Region that covers 29 counties. Sub-region stakeholders consist of over 75 individual organizations and groups of providers and users. The project’s intent is to increase the on-time schedule performance of the Metropolitan Transit Authority’s (MTA) 5700 buses over their 2800 miles of service routes in all five boroughs and improve the overall intersection traffic operation (delays, speed, air quality, etc.) specifically during the peak commute hours. This concept represents multi-modal management of the corridors and is consistent with the Active Transportation and Demand Management (ATDM) and Integrated Corridor Management (ICM) operational strategies. The project integrates the transit agency's bus operations with the transportation department's signal operations. The project provides a dynamic means to improve the transit operations and the corridor's capacity in terms of people throughput. It addresses the requirements specified in the Federal Highway Administration’s (FHWA’s) Code of Federal Regulations (CFR) 940 and the Federal Transit Administration’s (FTA’s) policy “National ITS Architecture Policy on Transit Projects”. These documents are commonly referred to as FHWA
