I live and commute around the DC metro area. Our roads are pretty much at, or beyond, maximum capacity during rush hour. It’s already at the point where traffic accidents cause huge delays for thousands of people. Just this morning, they had to close all of I-495 the Capital Beltway because, I’m not joking, a tractor trailer lost its rear wheels, blocking all lanes. Check out this traffic alert from WTOP, reproduced below:
Accident: tractor trailer lost it’s REAR WHEELS. **ALL LANES ARE BLOCKED.** DELAYS BEGIN NEAR THE MERGE WITH THE 270 SPUR. 270 SOUTH IS SLOW FROM FR HURLEY BLVD TO THE OUTER LOOP.
As I can attest, traffic was indeed blocked starting from right before Route 7 (where I get off for work, lovely). According to traffic reports, the problem caused backups all the way onto I-270 (a different highway) and up into Maryland! That’s approximately 13.5 miles of backup on two different major, multiple-lane highways. My back-of-the-envelope calculations put that at about 7,000 – 8,000 cars.
Assuming some cars have more than one person per car, we’re talking upwards of 10,000 people stuck in traffic. If we assume it takes one hour of sitting in traffic waiting for them to re-open the lanes and for traffic to resume, and we assume that the average commuter gets paid $30/hour, then that adds up to over $250,000 in lost productivity.
I’d like to think we could use market forces to create an added incentive NOT cause accidents. By levying additional fines against those who cause accidents, it would be nice to think we could affect people’s behavor. But causing an accident already has a significant negative financial impact (the cost of fixing your car and paying added insurance). So clearly we need a non-monetary penalty. Maybe revoking the at-fault party’s driving privileges? Maybe just public shaming. But something.
However, I’m concerned that this might create a dis-incentive to involve police in an accident and might cause an increase in hit-and-run accidents. What we really need is better mass transit, separation of trucks and cars, or maybe just cars that drive themselves, altho we saw how well that works when the trailers full of robots attack your self-driving car.
Maybe traffic is one of those unsolvable problems, like spam, religion, people who use the term “izzle” after certain words, and teenagers.
