But if you're going to limit connected cars to maneuvers that would still be safe with cameras, what do you gain?

But isn't the whole point of connected cars to let cars make maneuvers that would be dangerous if it was reacting only based on sight?

If it's not unhackable, then there will won't be much benefit. People won't put up with a system where a single hack could result in a multi-car pile-up. Maybe you could get some small improvements like simultaneous acceleration from stops (since the worst case scenario would be a series of...

But is making something unhackable truly be feasible?

Considering that transferring to the BL will be faster unless your traveling to the Seaport or RL from SS and further south (and that's assuming no congestion in TWT or the Seaport), I would argue, the blue line transfer is a bigger deal than the a red line transfer. SLG will not stop at the...

I'm curious to know how likely people think interconnected AVs are? I would think the cybersecurity issues would make it far too risky.

Does anyone know if the 47/CT2 stop by BU Academy is getting eliminated? It doesn't look like it will meld well with the bike lanes.

Also tunneling under Tremont would require tunneling under the Green Line.

There are only 2 lanes of traffic on Mass Ave between Putnam and Central, but Ari was making a proposal for the north of Harvard portion.

The BUS's scheduling emphasizes this. It's every 10 minutes during peak and every 20 minutes midday (10am-4pm), which is okay for serving BU CRC to BUMC demand, but is almost useless for serving intra-CRC demand (particularly when the weather is bad) since most BU classes are between 10 and 4...

These could all benefit bus speed too (signal priority depends on how its implemented) and don't affect the bus's acceleration and braking speed advantages.

The 57 beats the Green Line between Kenmore and Packard's Corner at least 90% of the time, so having the 57 run in the median would lead to the 57 getting stuck behind green line trains.

The issue with the current routing is in Connecticut and the residents around the existing route in SW CT have shown staunch resistance to straightening out the route there. The other alternative would be building a new corridor from Hartford to Providence. This would be ideal, but since there...

A potential plus I can think of for a Springfield train (if it is truly a "bullet train") is that 2/3 of the route could be used as part of a New Haven-Hartford-Worcester-Boston NEC reroute. But the the logic here should be "If we're already doing Boston-Hartford, it might be worthwhile to build...

Why can the RL support a lower headway than the OL? I would've expected the OL would have a lower theoretical limit due to its lack of sharp curves.

BU announced it was ending its affiliation with Huntington back in 2015.

That's valid. My idea was for some policy that might encourage ridesharing services to look like some sort of hybrid of Bridj and slugging.

Musk seems to be trying to address the problems that: Boring tunnels is too expensive Our main traffic arteries don't have enough throughput While doing this, he is ignoring the bigger problems that: Infrastructure connecting tunnels to the surface is too expensive Everyone likes to get...

I'm beginning to wonder if self driving cars will actually be "good" for traffic as people often indicate. My understanding is that most of the potential ways self driving cars could reduce traffic actually come from connecting cars which is likely a lot further out if that happens at all (the...

Re: Amtrak / Regional Rail Discussion Thread The route is really curvy in New London county. NEC Future has been throwing out some plans for straightening it out, but the local residents are very opposed. I believe the other end of the state has issues with the lines being overcrowded between...
