Good news - UConn's made a searchable database of all the accident records in the state from 1995 onward. There are two sections - the crash summary tool, which anyone can access, and the data query tool, which required a (free, unrestricted) account. If you're at all interested in crash records, I'd recommend checking it out.

http://ctcrash.uconn.edu/

The whole thing is set up so you can click and drag to make graphs really quickly, and you can also see diagrams of the accidents, sort by any factor imaginable, or even look at our Photolog at the crash location.



Ped fatalities have decreased somewhat over the past two decades, but major ped injuries have sharply declined. A lot of that is due to more stringent auto manufacturer standards to improve ped safety.



In the same time, motorist injuries have decreased as well, though not at the same rate.



In Union, our least populous town, there have been 193 crashes in the last 3 years. This is a diagram of one of them.



In Newington, just in 1998, there were 197 accidents on Route 15 alone. Here's the location of one of them.

And before you guys ask, yes, you can search by age. I think there were about 180 crashes where someone 5 and under was driving.

Best bit about this is when it happens in the UK and the kid goes to court and they get "banned from driving".

I don't know how that works with an 11 year old.

I'm betting, in most of these cases, their parents leave them momentarily in a running car / keys in the ignition. The kid pulls up the parking brake, whoops, now the car's rolling down the street and into someone's mailbox.

Only one of those accidents resulted in a fatality, but still, you've gotta feel like poo poo if your kid even gets a bruise that way.

It's possible in the DPS records, but the ConnDOT records are cross-checked pretty carefully. I don't think every accident in there is gospel, but I'd be surprised to see more than a couple errors like that. From what I'm told, the database throws up warnings when someone tries to put a young age in it (along with roads going the wrong direction, wrong town, wrong exit number, that sort of thing.)

I think I recall seeing similar stats nationwide for the UK -- decreasing overall injuries from car accidents, but stable (or only slowly decreasing) fatalities. They suggested that the decrease in injuries might be due to cars being built with more safety features, but that the lack of a decrease in fatalities (or increase in the chance of a car accident being fatal, if you will) might be due to cars being bigger and hence more momentum being involved.

The new shopping center in the bottom left is going to be a traffic headache no matter what, but creating three new interchanges within a couple thousand feet of that cloverleaf just looks crazy. Also, they've removed some of the old roadways that are no longer needed in this image, but left the upper left cloverleaf - does it serve a purpose or just a mistake?

At first blush, this looks a little dicey, but the cloverleaf interchange actually interacts with collector/distributor roads on I-10, so it's not so unreasonable. Ditto the other new entrances / exits.

And it's not actually even a full cloverleaf, since there's no weave present for the northeast quadrant. And like you said, the northwest quadrant of the cloverleaf (if property connected, looks like an oops) would act only as a U-turn for traffic going from NB I-110 to SB I-110.

Apologies if something similar has been posted before but:

I just moved to Santa Clara, Calif, and I live right off of El Camino Real. One thing that bugs the hell out of me is that this road--lined with stores, restaurants and bus stops as it is--has very few crosswalks. So here's an idea: if you have two intersections that are really far apart, why not add a controlled crosswalk halfway between them. Then the signals for each half of the crosswalk could be synchronized with the light down the road so that they turn green either simultaneously or in sequence. Sure, pedestrians have to cross the road in two halves, but I'd rather jaywalk across half of el camino than all of it.

A good example of what I'm talking about is the stretch of El Camino Real in Sunnyvale between Bernardo and Sylvan. Over a quarter mile between crosswalks, and they for some reason thought it was a good idea to put a bus stop smack dab in between them.

Mid-block crossings are pretty common out here. We've been planting them all over the place - most recently on New Britain Avenue in West Hartford to connect a prominent local business to its parking lot across a busy four-lane street. It's not cheap to do properly, but mid-block crossings make the whole area much more friendly to pedestrians.

Jeoh posted:

This is an option for a very wide or busy road. Unfortunately, from what I've seen, many people will choose simply to cross at grade, even if it's a freeway. We have a fatality every month or two from a pedestrian trying to cross a freeway on foot, often when there's an overpass just a short walk away.

I really like that design used for suspending signs.

Our latest stuff looks bad, and the signs are smaller than the ones they're replacing. They also aren't very reflective, cheap all around. But cutting corners is the core belief of our current government.

No room for it, the businesses come right up to the sidewalk. Plus, it would be used by like maybe 10 people a day.

Plus, 50% of the time there's not enough traffic to justify a pedestrian bridge, and when there is it's moving so slowly that an extra crosswalk wouldn't really hurt it much.

You really have to watch this right up to the end; the sign actually falls off in the last two seconds of the video.

OK, here's a serious traffic planning question.

I present the Stanley Park Causeway:

1.8km of 3-lane road with switchable lane direction connecting the Lion's Gate Bridge to downtown Vancouver. It serves its purpose fairly well for motorists as the major arterial connection between West Vancouver and downtown. However, it is also a major route for cycle commuters. In fact, it is the only route through Stanley Park (a forest under conservation) that is lit, so cycle commuters don't have much choice during winter.

The cycling infrastructure, however, consists of a narrow sidewalk shared with pedestrians, with a one-foot drop to the motorway. The road is on a slope, so this works reasonably well on the uphill side, where cyclists don't go much faster than walkers. On the downhill, it creates an extremely dangerous situation, with cyclists picking up speed, but running the risk of falling into traffic if they lose control of their bike. This happened a month ago, and the cyclist in question fell in front of a bus and was killed instantly.

Needless to say, the fatality has had cycling advocacy organisations, as well as the City of Vancouver, and the Provincial Ministry of Transportation (who are actually responsible for the stretch of road) looking for solutions. Nothing concrete has been suggested yet.

The question I have is, what would you do to make this road safer for cyclists (and pedestrians)? Would a railing be enough? Maybe separated paths for cyclists and pedestrians (but could these be put in place without cutting down trees)?

This is not an entirely moot question. I am involved with one of these cycling organisations, and so far our position is just that "something" needs to be done. It would be good to nail that down to some viable proposals we can start lobbying for.

A series of shuttles that run back and forth across the stretch of road, ferrying cyclists from one end to the other. Safe and efficient. If cyclists are concerned about their environmental impact of their activity they can give the driver like $2 for the gas or something.

We can solve this problem with more cars, not fewer cars.

Looking at Streetview, a cheap solution could be to convert the sidewalk on one side of the road into a bikepath, and the other side into a pedestrian route with no bikes allowed. Broaden the bikepath where possible, and add a railing.

That was my first thought as well. That solution does require widening the pavement on the bike side, since it currently looks a bit too narrow to have two bikes meet at reasonably high speeds. Would involve moving a few lamp posts on the bike side.

Not sure which is worse though, having no railing and risking running into traffic, or running the risk of falling head over heels over a railing, into traffic...

Yes, the bridge is also an issue, albeit something of a lesser one. The focus right now is on the road going through Stanley Park to the bridge, however.

I'm told the bridge may become transit/ped/cyclist only at some point between now and 2040, although I'll believe that when I see it.

Jethro posted:

Road users in general don't care much about the rules; good traffic design should try to provide as few opportunities for them to do stupid/illegal things and kill themselves/others as possible.

The real issue I could see with having one side bikes only and the other peds only is that a pedestrian caught on the bike side has nowhere legitimate to go after they get buzzed by a bike halfway along the path and realise they're on the wrong side (and vice versa).

I'm pretty sure that the majority of cyclists, if given the choice between a shuttle (that would probably only run every half- or quarter-hour at best), and taking their chances on the lovely infrastructure, would choose the lovely infrastructure.

For reference, there is one bike shuttle in the region, and although it works, it's really quite a headache (where if the infrastructure in question had been a bridge rather than a tunnel, it would have worked a lot better.)

Wait - you were being ironic, weren't you?
