Boston Using IBM Engineers To Solve Traffic Problems 178
vu1986 writes "Boston won the opportunity to pick the brains of six IBM engineers — including one from Tokyo — who flew in to check out its traffic situation and figure out a way to consolidate, analyze and use existing traffic data feeds as well as new data sources including (of course) Twitter feeds, to ease the city's notorious traffic jams."

In my limited experience in Boston, the problem wasn't the people living within the dense urban environment, it was the people coming in from the suburbs that was the problem. In fact, it was only some of those people because many drove to train stations and rode those into the urban center.
Now, contrast that with Los Angeles where people can live less than five miles from work but still drive in knowing it will take 45+ minutes--at least twice as long as it would by bike and almost as much time as it would

Actually, my point was that I wanted to use full size bikes with transit, as their electric options are vastly cheaper than an electric folding bike (which is already expensive). But with a lot of mass transit as it is today, only a folding bike (such as the brompton) is the only thing allowed on board. Add electric to that and it becomes at least a $2500 proposition. A regular shitty electric bike can be had for $500.

Full size bikes are actually a problem, and I speak as someone who wishes it were easier. If you look at the "bike cars" run by CalTrain between San Jose and San Francisco, they devote half the floor space (i.e., 3/8 the capacity of one car) to a mere 40 bicycles (8 stacks of 5). That's a big capacity hit (if Caltrain actually ran full of people on a regular basis). The time to load and unload is also an issue; it takes longer, and that can delay trains, which can delay the trains behind them.

So all you need to do, is to introduce 1st and 2nd class compartments in public transportation. That way, rich folks can still feel rich by traveling 1st class, and the poor folks can feel better about themselves, because they ride in the same transportation as the rich folks.

Re:Free the market (Score:5, Insightful)
There are really three-ish basic possible positions(though it is certainly possible to mix and match and hedge and squirm a bit at the cost of some complexity, and certain sorts of 'public' things fit more naturally into one category or another).
1. 'Public' in the sense that ownership is vested in some body that represents 'the people', but exploited under the usual conditions of profit maximization. This one crops up with mineral and other natural resources most frequently. The nominal owner is 'the people'; but the obvious expectation is that 'the people' will sell/lease/etc. the asset for the best possible price to some other entity and then rake in the cash.
2. 'Public' in the sense that ownership is vested in some body that represents 'the people', and that the property in question is, in some sense, 'for' the people as well as owned by them. National Parks are the most obvious example. They are 'owned' in approximately the same sense as above; but public opinion would likely be hostile if we simply sold them off and cut everybody a check. There is a sense, often poorly articulated; but reflected in generally low ticket prices, that 'the people' should have enjoyment of them, as well as ownership.
3. 'Public' in the sense of being a necessary response to market failure. Utilities are the most obvious example. Unlike #1, 'the people' are both the owners and the customers, so profit is generally seen as a bad thing; but unlike #2, where appeals to intangibles like 'national heritage' are common, public opinion generally just wants the system to run not-for-profit; but as efficiently as reasonably possible.
If you adopt market-based pricing for roads, you are (though it is not polite to say so), adopting the theory that, if enough people cannot afford access to this 'public' feature, it will be more efficient, and more pleasant for the remainder who can. This isn't necessarily wrong; but it implies that you are essentially rejecting the notion that 'the people' have any right, beyond that of 'customer', to the enjoyment of a 'public' facility. This is pretty uncontroversial in something like a mineral deposit(Show of hands: would you rather have the right to grab your shovel and go get your share of the bauxite, or just sell the mineral rights to FooCorp and get your share of the proceeds?); but becomes a bit thornier when the 'public' asset is something more like a utility. Is a 'public' road a thing that 'the people' have the right to use, or is it something that 'the people' sell, by means of their representatives, to the subset of them that can afford the equilibrium price of access?

If the revenue from congestion tolling a road is invested back into the road, it lowers the amount of money that must be collected from the gas tax in order to maintain the road. Therefore, congestion pricing transfers wealth from people who can afford the market rate for travel during peak periods to those who can only afford the off-peak rates.
And because the gas tax and other user fees only cover 65% of the cost of the roads [subsidyscope.com], then congestion pricing also reduces the road's maintenance burden on people who cannot afford to drive at all.

There's one place on the freeway near me that is almost always bumper to bumper. The road before and after this spot is usually fine. What's the problem? Some idiot highway planner designed an on ramp that comes up to the (elevated) highway level blind, then the merge lane is nonexistent. So anybody coming up that on ramp finds themselves suddenly in a highway lane, and anyone in that highway lane instantly tries to move over to the left, etc. The problem could be solved by either making a reasonable acceleration lane at highway level, getting the on ramp to highway level faster, or even blocking off the rightmost lane of the highway (generally the highway isn't at capacity anyway).
