A Freight Plan for the NYMTC Region 4.0 Relationship among Performance Measures and Deficiencies and Recommendations The project team developed performance measures to provide benchmarks for assessing strategies and actions. Tables 4.1 through 4.4 provide a connection among the evaluation criteria, the identified deficiencies, and the first round of possible solutions. They are organized by the four primary modes – highway, rail, water, and air. This plan addresses deficiencies “outside the gate,” although other deficiencies were originally identified. Possible projects and solutions were later refined to reflect the projects included for analysis in Section 5.0. The deficiencies of the freight system were identified through the findings of several earlier reports: Internal and External Scan (Task 1), Existing Conditions report (Task 2) and Needs Assessment (Task 4). The deficiencies analysis served as a baseline for developing and testing alternatives. The tables in this section are intended to show, in outline form, the evolution of project definitions over time, and their relationship to performance measures and deficiencies. The solutions listed represent an initial menu of actions, prior to evaluation. For current project definitions and detailed descriptions of benefits and impacts, turn to Section 5.0.

A Freight Plan for the NYMTC Region Table 4.1 Highway Analysis Summary Table Task 4 Task 5 Performance Measures Current/Anticipated Deficiencies Possible Solutions/Alternatives Operating Measures: • Truck volumes (with respect to total traffic volumes) • Levels of service (LOS) for major truck routes • Average speed • Toll costs • Curbside space management (loading/ unloading zones, parking enforcement, etc.) • Accident and incident rates Physical Measures: • Height clearances • Turning radii • Access width • Weight limitations • Truck delays at railroad/highway grade crossings • Usable shoulders • Highway design standards, acceleration/deceleration lanes, truck climbing lanes, etc. • Signage; and • Curbside capacity (for truck operations) Operating Limitations: • Chronic congestion on many regional roadways • Poor signage along surface truck routes • Bridge and tunnel crossings act as “choke points” for regional traffic Limitations on Truck Access: • “Gaps” in regional freight network caused by truck-excluded roadway segments (ex., Grand Central Parkway) • Legally and illegally parked vehicles on already narrow and difficult to navigate surface streets Limited Truck Routes: • Trucks with 53-foot trailers are prohibited from serving destinations within New York City • Only one truck route within the NYMTC region for interstate-standard 53-foot trailer vehicles serving Nassau and Suffolk Counties (New England Thruway, Throgs Neck Bridge, Clearview Expressway, Long Island Expressway) No limited-access, highspeed truck corridors in Manhattan (except the one-mile Trans-Manhattan Expressway) • Gowanus Expressway/Brooklyn Queens Expressway/Long Island Expressway is the only east-west truck route between Southern Brooklyn and Queens/Long Island • Long Island Expressway is the only east-west highway open to trucks serving Nassau and Suffolk Counties • Cross-Bronx Expressway is the only east-west arterial for the Bronx Infrastructure Improvements: • Eliminate vertical clearance limitations on highways that cause truck diversion to local streets (e.g., on BQE at Brooklyn Bridge) • Improved signage • Create new roadway links to access major truck trip generators (e.g., direct Hunts Point connection to the Bruckner Expressway) • Reconstruct bottleneck interchanges to improve flow (e.g., Highbridge Interchange) • Develop new east-west connector serving South Brooklyn and JFK Airport, on either new right-of-way or modification of existing routes to permit trucks • Develop continuous service roads along major highways to provide alternate truck routing in case of incidents • Increase capacity and lane widths at the Goethals Bridges • Improve capacity on the Tappan Zee crossing • Improve Sheridan-Bruckner Interchange and access to Hunts Point Market. Policy Improvements: • Investigate the use of key parkway segments by smaller trucks and vans to eliminate gaps in the truck network (e.g., one-mile pilot study of the Grand Central Parkway between the Triboro Bridge and BQE) • Allow smaller commercial vehicles to use parkways during nighttime hours (9:00 or 10:00 p.m. to 6:00 a.m.) Note: The tables in this section are intended to show, in outline form, the evolution of project definitions over time, and their relationship to performance measures and deficiencies. The solutions listed represent an initial menu of actions, prior to evaluation. For current project definitions and detailed descriptions of benefits and impacts, turn to Section 5.0.
