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