Cool idea. This seems like a big caveat though, >> With today's traffic volumes, queues would vanish and travel delays would be cut to almost zero. I’m pretty sure it’s critical in traffic engineering to consider how the design would hold up in the event of larger volume given greater efficiency. There’s a single lane exit on the Mass Pike about 5 miles outside of Boston that’s always backed up onto the highway. I’d always wondered why they hadn’t added a lane, put a divider, or otherwise designed the exit differently. A few years ago a former colleague met the engineer who did the traffic analysis for that exit. Apparently adding capacity to achieve greater throughput would’ve resulted in worse traffic at the exit. According to the models they developed, the more constrained solution was actually optimal, although to the frustrated driver (me!) it still seems poorly designed. Granted, this is an example of increasing capacity rather than improving efficiency. Regardless, I’d be interested to see how the MIT solution holds up to increased traffic volume.
