(WNYC Newsroom). Trucks making deliveries after seven pm and before 6 am shaved an average of forty eight minutes on their routes. That's according to the results of a pilot program by the New York City Department of Transportation. City Transportation Comisssioner Janette Sadik-Khan says the off-hour delivers also resulted in fewer parking tickets, down from$1000 per truck to almost nothing. The four month pilot enlisted thirty-three companies around Manhattan, including Foot Locker, Whole Foods, and Cisco. Some businesses have expressed reluctance to schedule off-hour deliveries because it can cost more in overtime and make last-minute deliveries more difficult. And some have said it's not an option for perishables.
