INTRODUCTION The Verrazano-Narrows Bridge is one of the largest facilities of the MTA Bridges & Tunnels, serving on average approximately 200,000 vehicles daily. Approximately 75% of this traffic uses E-ZPass. The bridge is a critical link for the regional traffic, connecting the two adjacent states of New Jersey and New York via Staten Island and Brooklyn. As part of the VN-03 (Verrazano-Narrows Bridge Toll Plaza Improvement Phase-B) project, three ITS sub-system elements, Variable Message Sign (VMS), CCTV cameras and Lane Control Signals (LCS) are planned to be installed by MTA B&T, at the Staten Island Expressway (SIE) approaches to the bridge. The three ITS sub-systems mentioned above have been in place at the bridge for many years. However, due to the planned reconstruction at the SIE by the NYSDOT project (PIN X731.30), the devices need to be replaced and relocated, since the SIE approaches to the bridge will be reconfigured, with the new construction. Together the three sub-systems (VMS, CCTV and LCS) have been effectively serving the regional customers, while operated by the VN staff at the facility. They provided critical safety, traveler information and traffic management information and services to the travelers. Each serves different but related functions. The existing VMS provides traffic related information to travelers including a determination point as to whether to use upper or lower level of the bridge. With development of advanced traveler information services at the bridge, the VMS are also planned to provide customers travel time information for the lower and upper level of the bridge and other locations, which will be posted and updated by the MTA B&T traffic operators at the facility. The existing CCTV cameras serve the operations staff of the bridge with the ability to monitor traffic flow at the approaches to the bridge and check the status of VMS messages and Lane Control signals. The existing Lane Control Signals (LCS) along with Changeable Message Signs (CMS) inform travelers which section of the bridge (upper or lower) is open or closed at any given moment, with markings of green colored arrow signal (for open) and red “X” signal for closed. The locations of these subsystems and devices under the new configurations of the new approaches to the bridge will be determined with appropriate surveys by field engineers. The survey data will be incorporated into the final design by the engineers of the MTA B&T in consultation and coordination with NYSDOT. For instance, the LCS’s will be placed at strategic locations on the SIE approaches to the bridge, at a decision point where customers will choose in 1 advance the correct route, or if necessary be directed to the upper or lower Level of the Verrazano-Narrows Bridge. 2 The Verrazano-Narrow Bridge Approaches from SIE. Figure 1 Staten Island – Project Study Area 3 1.1 Report Organization This document is intended to provide the Project Systems Engineering (SE) Analysis of the MTA B&T ITS Subsystems, which will be implemented at the Staten Island approaches (on MTA B&T and NYSDOT jurisdictions), and will be connected to the MTA B&T ATMS system, in the traffic operations center at the Verrazano-Narrows Bridge. For list of subsystem devices and locations, please see Appendix ……. The SE analysis will include the following: An overview of the MTA B&T planning process for the ITS Program of the Authority. Overall architecture for the MTA B&T ATMS and the VN-SIE Approaches ITS Subsystems identified for this project (see above). Communications requirements for all components of the subsystem. Functional requirements for the subsystems to determine conceptually the requirements for locations, hardware, software and interconnection. The report contains the following sections: Section 1: Introduction Section 2: MTA B&T ITS Planning Process for ITS Program & Projects. Section 3: VN – SIE Approaches ITS Sub-Systems Section 4: Participating Agencies Roles and Responsibilities Section 5: System Functional Requirements Section 6: Analysis of Alternatives Section 7: Procurement, Operations, and Management Options Section 8: Applicable ITS Standards and Testing Procedures Section 9: “V” Model Cross Linkage Summaries 1.2 Intended Audience This VN-SIE Approaches ITS Subsystems System Engineering Analysis is intended for: MTA B&T Engineering, Operations, Technology and other stakeholder departmental staff Members of NYSDOT
