The problem is parking. And the solution is obvious: multiple truck-length parking spaces along each and every block, for exclusive use by delivery vehicles, car ride services waiting for pickup, and moving vans. Which, logistically, would be relatively trivial to implement -- just painted lines and signs. Street parking needs to be reprioritized for the needs of 2019, not 1950.
It's insane and irresponsible the article doesn't even suggest street-level fixes like this, and instead seems to imply that the problem is with irresponsible/unconstrained trucking/deliveries.
Most misleading quote of the article: "“What percent of your deliveries are truly urgent — 5 percent or 2 percent?” said Mr. Holguín-Veras, the Rensselaer professor."
What has urgency got to do with it? Whether my package gets delivered in 1 day or 7 days, it doesn't change the number of trucks on the road. And if it's truly urgent, then that's when I'm running to the store, not ordering a package. Sheesh.
