APPENDIX C - Transit Deployment Figures Lower Hudson Valley ITS Early Deployment Planning Study EXECUTIVE SUMMARY Project Location The Intelligent Transportation Systems Early Deployment Study of the Lower Hudson Valley area focuses on the regional transportation network including freeways, arterial routes and the local and express bus and train systems in Westchester, Rockland, Putnam, Dutchess and Orange counties. Purpose of the Project The purpose of this study is to provide the framework for future implementation of Intelligent Transportation Systems (ITS) in the Lower Hudson Valley area. The focus of the planning study is the regional freeway system, major arterial routes and the regional transit system. The project will identify the appropriate ITS User Services and develop the Strategic Deployment Plan necessary to implement these user services. The process will build upon existing ITS initiatives and incorporate them into an overall regional plan. The end product will be a broad conceptual plan that will guide the future development of a real time transportation information system and regional transportation management system for the Lower Hudson Valley. Goals The general goals of ITS are to effectively manage the transportation system, to reduce congestion, to improve mobility and increase safety on the freeway and arterial roadway network and the regional transit system. For this project, five primary goals have been developed: · Provide efficient use of the transportation network through the implementation of an Advanced Transportation Management System (ATMS). · Improve communications to the users and providers of the transportation network by establishing an Advanced Traveler Information System (ATIS). · Improve safety by reducing incident response and clearance times. · Develop a funding plan or mechanism for ITS that is in line with expected benefits. · Promote feed back and ongoing evaluation of the process. Benefits of ITS The benefits of Intelligent Transportation Systems (ITS) have been outlined in a report prepared by The MITRE Corporation entitled “Intelligent Transportation Infrastructure Benefits: Expected and Experienced”. This report was prepared for the Federal Highway Administration, and published in January 1996. The use of ITS technologies has demonstrated positive effects on several Measures of Effectiveness (MOEs). Below is a sample of several ITS initiatives and the associated benefits: 1 Lower Hudson Valley ITS Early Deployment Planning Study Expressway Traffic Management Systems Decreases in travel times of 20% to 48% Increases in travel speeds of 16% to 62% Increases in freeway capacity of 17% to 25% Decreases in accident rates of 15% to 50% Decreases in fuel consumption during congestion of 41% Annual decreases in emissions of 122,000 tons of carbon monoxide (CO) Annual decreases in emissions of 1400 tons of hydro carbons (HC) Annual decreases in emissions of 1200 tons of nitrous oxide (NOx) Arterial Traffic Signal Systems Increases in travel speeds of 14% to 22% Reductions in travel times of 8% to 15% Reduction of vehicle stops by 0% to 35% Reduction in delays of 17% to 37% Reductions in fuel consumption of 6% to 12% Annual decreases in automobile emissions of 5% to 13% of the CO Annual decreases in emissions of 4% to 10% of the HC Incident Management Programs Reduced incident clearance times of approximately 8 minutes for stalled or disabled vehicles Reduced incident clearance times of approximately 5 to 7 minute for removing damaged vehicles with a wrecker Travel times also decrease with the reduction in time it takes to remove vehicles from the travel lanes. These decreases in travel times average 10 percent to 42 percent. The decrease in the total number of accidents is approximately 35 percent. The reduction in secondary incidents due to incident management programs was estimated at 30 percent in a before-and- after study conducted by the Texas Transportation Institute for the San Antonio TransGuide System. Traveler Information Systems Reduction in travel times of 20% during incident conditions Decrease of 1900 vehicle-hours of delay per incident Decrease of 6% to 12% in fuel consumption Decrease of fuel emissions from the affected vehicles of volatile organic compounds (VOC) by 25% Reduction in HC by 33% Decrease in NOx by 1.5% 2 Lower Hudson Valley ITS Early Deployment Planning Study Project Advisory Group (PAG) In order to facilitate a consensus among transportation agencies, a Project Advisory Group (PAG) was formed. This group included: NYSDOT PIP Commission FHWA Westchester County NYMTC Rockland County Mid Hudson South TCC Orange County NYS Police Dutchess County NYS Thruway Authority Putnam County TRANSCOM City of White Plains NJHA Metro North Connecticut DOT MTA NYS Bridge Authority The PAG members guided the development of this deployment plan by providing input and suggestions during the planning process. Current ITS Initiatives There are a number of existing and planned ITS projects in the Lower Hudson Valley. Below is a list of these projects in operation or design (Additional information on each is contained in the report): · NYSDOT · HELP · NY-WINS · EZ Pass · Transmit Project · Model ITI Deployment Project · Transit AVL in Westchester County · I-95 Corridor Coalition Information Exchange Network (IEN) · SATIN Project · Highway Advisory Radio (HAR) · Regional Variable Message Signs (VMS) · NYSTA-CCTV, VMS, HAR · IRVN Network · Rockland AVL System · Closed Loop Signal Systems · City of White Plains Signal System · Westchester Avenue Signal System 3 Lower Hudson Valley ITS Early Deployment Planning Study Existing Transportation Conditions The areas of greatest recurring congestion focus in Lower Westchester and Rockland Counties centering on the I-287/I-87 corridor. In lower Westchester County, the main recurring congestion occurs along the following north-south routes: Saw Mill River Parkway, Sprain Brook Parkway, Hutchinson River Parkway, and I-95. In the east-west direction, I-287 and the Cross County Parkway meet the criteria for recurring congestion. In Rockland County, I-87/I- 287, the Palisades Interstate Parkway, as well as Route 202 show signs of recurring congestion. In Putnam County, the recurring congestion can be found along Route 6, Route 22, Route 312 and I-84. In Orange County, recurring congestion routes include Route 202 and parts of Route 17K. The focus of recurring congestion in Dutchess County centers on Poughkeepsie, with Route 9 and Route 9G, as well as a section of Route 82 in Hopewell Junction. Aerial flights were also used to verify and determine areas of recurring congestion. In addition to the recurring congestion developed from the analysis of volumes, the aerial flights found volume-related congestion, on at least one occasion, in the following areas: · Route 6 in the Peekskill area · Route 35 near FDR State Park · Taconic State Parkway in the Yorktown area · Routes 9, 9A and the Taconic State Parkway in the Ossining area · Route 35 and I-684 in the Lewisboro area · Saw Mill River Parkway in the Mt. Pleasant and Hastings areas · Route 59 paralleling I-87/I-287 in Rockland County · Route 45 in the Spring Valley area · Route 9 in the Poughkeepsie area · Taconic State Parkway in the Mt. Pleasant area (has since been upgraded to 6 lanes) The greatest amount of nonrecurring congestion related to the daily accident and incidents that occur on the Region’s facilities can also be found in the Lower Westchester County area and in Rockland County. The Palisades Interstate Parkway, Sprain Brook Parkway, Hutchinson River Parkway, I-87, I-95, as well as some of the east-west routes such as I-287/I-87 and the Cross County Parkway all experience significant levels of nonrecurring congestion. In Rockland County, parts of Route 202, Route 9W, Route 17, Route 59, Route 303 and Route 45 all have some amount of nonrecurring congestion. In upper Westchester County, parts of Route 6, Route 35, Route 133, Route 117 and Route 172 experience nonrecurring congestion. In Orange County, parts of Route 202, Route 208, Route 32, Route 17, Route 9W, Route 211, Route 17M and Route 17A exhibit some amount of nonrecurring congestion. The routes that met the criteria for nonrecurring congestion in Dutchess County include Route 376, Route 44, Route 9, and Route 9G. The public transportation services operating in the Lower Hudson Valley provide significant mobility benefits to the region. These public transportation services include local public carriers such as PART, regional public service providers such as Metro-North and private operators such as ShortLine. According to the most recent Federal Transit Administration report, the public transportation service providers serving
