Truck traffic illustrates the good, and the bad, of congestion. When the economy is improving (and gas is cheaper), the number of deliveries and service calls goes up. But, truck traffic on streets not designed for large vehicles or heavy volume causes accidents and increases gridlock and general congestion.
There are really two different kinds of problems:
Trucks in places they shouldn't be. The current toll system--where some routes into Manhattan charge tolls and others are free--creates bad incentives. For example, trucks going from Long Island to New Jersey should go across the Verrazano Bridge and the Staten Island Expressway, both designed for heavier traffic. But a truck can save up to $80 in tolls by using the Manhattan Bridge and Lower Manhattan and Downtown Brooklyn streets, which are older and not designed for this kind of traffic. The larger the truck, the more the toll savings--and the worse the impact on neighborhood congestion, safety, and air quality. To read about and discuss one idea for dealing with this problem, go to Topic 4.1 - The "toll swap".
Trucks in places they need to go. Congestion and other problems from commercial vehicles that need to make pickups, deliveries, or service calls in the CBA and surrounding neighborhoods is trickier. Some people argue that NYC should require "off-hour deliveries" (OHD). In fact, NYC was the first to actually study how OHD would work. A 2010 pilot project, with 8 delivery companies and 25 business customers, found that makings deliveries between 7 PM and 6 AM significantly improved travel time, shortened delivery stops, and saved parking tickets and fines. Drivers really liked it, and customers benefited from having deliveries reliably there on time. (See report, PDF, p. 62-62)
So why not make this the law for everyone? Researchers from RPI who worked on the pilot concluded that OHD is a great idea in the right circumstances. The change obviously increases costs if businesses that ship and accept deliveries have to hire people to cover the new hours ("staffed deliveries"). In fact, after the pilot was over, all the staffed delivery customers went back to daytime deliveries because the pilot subsidies stopped. Also, area residents may be affected by nighttime noise. Other studies have found that banning large-truck daytime deliveries not only raises costs but also creates new problems, like companies dividing daytime deliveries among more smaller trucks (See studies cited p.41). And the Federal Highway Administration worries about where large trucks will park while waiting to get into the delivery area. The RPI researchers advised NYC to aim for OHD in 14-21% of staffed deliveries and 40% of unassisted deliveries. (At the time of the pilot, NYC had only 4-5% total OHDs). NYC-DOT continues to recruit carriers and customers to switch to OHD.

A longer term solution might be the proposed Cross Harbor Rail Freight Tunnel. The huge majority of NYC and Long Islands freight comes in by truck, and this is expected to increase in the future. The proposed tunnel, between Jersey City and Brooklyn, is predicted to take 700-900 trucks a day off roads in the region. The Port Authority and the Federal Highway Authority just issued the Tier 1 final environmental impact statement, which narrows the proposed alternatives (PDF) to a basic rail tunnel and an enhanced railcar float system (carrying rail cars on barges). Planning and approval still have a long way to go--and it's an open question where the money would come from (PDF). The tunnel would reduce a lot more truck traffic, but is also a lot more expensive.
►Will the "toll swap" encourage trucks to use the routes designed for heavier traffic?
►What do you think about the Cross Harbor Rail Freight Tunnel as a possible long-term solution?

Rail freight to Brooklyn / Queens is the obvious long term solution to NYC freight congestion. We're one of the only major cities that doesn't feature rail freight infrastructure and that's why our crossings are crowded with loud, polluting 18-wheelers. We absolutely need a rail route for shipments onto Long Island, and since shipping companies stand to benefit greatly from such an addition I believe that they should be identified and approached to contribute funds to such an endevour, to help defray costs to the public.
But there is still the issue of last-mile delivery, which rail freight does not address. Besides the daily movement of freight trucks through Manhattan, there is also the constant influx of local deliveries that is essentially the life blood of many NYC industries. Some large buildings are lucky enough to have private loading docks for these deliveries, but for the vast majority of businesses there is no accomodation, leading to this forced gray area of double-parking that you see on every Manhattan street at almost all hours. There is a VERY simple solution to this!: Paint a 50-foot stretch of yellow parking lane on every block as a 'loading area'. Ban long-term parking in this zone, be clear that it is only to be used for deliveries, and that deliveries on that block can ONLY be done from that zone. Half hour time limit. Fines for double parking on streets with an available loading zone should themselves be doubled. We have no guidance in place, no infrastructure for local deliveries and that is in my opinion grossly irresponsible. This would be guidance.

Thanks for your suggestions on loading zone parking, infinitesunrise. In one area, NY-DOT has added loading zones that are in effect at particular times in the day. What do you think of this idea?

Regarding truck access in NYC, the Truck Access And Vehicle Dimension Guidelines on DOT's website says that trucks with 53' trailers are not permited on local truck routes without a special permit for trucks with nondivisible loads, but every day I see such trucks on our streets. They are often making deliveries to grocery stores which are in no way nondivisible loads. Other cities in the world do not have such deadly trucks where they shouldn't be, and our laws seem to forbid this as well. Is the DOT's website wrong, or is the law just never enforced?

Thanks for your comment, Bicyclebelle, and the research you did on truck access. Could you share the link to the DOT site? I wonder if others could comment on whether they’ve seen the same enforcement problem that Bicyclebelle has observed?

See 'Truck Access And Vehicle Dimension Guidelines' pdf here:
http://www.nyc.gov/html/dot/downloads/pdf/truckaccess.pdf
And look for trucks with 53' painted on the trailer.

Rail would be ideal long term solution.
OHD would also be ideal. Staff would have to be increased but, I believe that time saved by not being part of traffic would benefit the greater good.

Charging trucks higher tolls just increases the cost of food and any product trucked to NYC. The truckers work on slim margin and are not eating those costs. I suggest you Synchronize the traffic lights city wide with strong imput from traffic engineers to create good traffic flow. Randomly Inhibiting traffic flow does not help the situation.This is the Bloomberg doctrine. Hurt drives ability to move and some how thats a good thing. You want product and people who drive; to flow and not sit and double the amount of time on the road which triples pollution. You could have traffic lights operate the old way and stay green for miles say from 4:30 am to 6am. Truckers would take advantage of this and get on and off the road earlier. So would some drivers. The outer bourghs need more access to good traffic flow than Manhattan due to existing infrastructure. Also main secondary streets need better flow for small business to conduct business...
