I've heard pluses and minuses to diagonal parking. For a busy street, reportedly, it's pretty dangerous, but I don't see how it could be more dangerous than parallel parking. It needs more lateral room but it should be a lot safer for bicyclists. There wouldn't be a chance to get doored in the bike lane, and people backing out will have to turn their cars on at least, which should give the biker some indication that there's danger.Rumpy Tunanator said:Go diagonal (if its on street parking, but it works both ways if its off-street)), you can fit more spaces to the block that way if your street is wide enough (or designated lot).
What do you know - you dont even own a car. I firmly beleive every driver should be required to ride a motorcycle in rush hour traffic, or ride a bycicle on the shoulder of an arterial for at least one week. You gain a HUGE appreciation for them.jordanb said:Drivers are so rarely looking for bikes anway. If drivers would simply check their mirror before swinging their doors open there wouldn't be any danger for bikers from parallel parked cars.
If a car had to move to be a danger to bikes, at least that'd give the biker some visual warning that would signal to him to be careful.
We have a fair bit of angle parking in commercial centres where we may want to maximise roadside parking, slow the traffic, or narrow the travelling lanes for pedestrians. We do however insist on rear to kerb - ie. so you back in and drive out. Backing in should be safer because you have just traversed the road you back over to get into your space. Using your mirrors to reverse should ensure there are no surprises. Provided you drive out slowly there should be no threat to bicycles when leaving either.Jeff said:But with diagonal parking you have huge blind spots if there is a car parked on either side of you. Diagonal sucks IMO, and is very dangerous for bikes because of the whole blind spot issue.
Table 7 – Minimum Car Space Widths
2.4 m Reserved parking with low turnover rates, such as employee car parking areas at industrial and commercial premises.
2.5 m Public car parking areas with low turnover rates, such as a sporting venue.
2.6 m Public car parking areas with moderate turnover rates, such as a Local Centre shopping centre or medical centre.
Reserved spaces where passengers and goods can be expected to be loaded or unloaded, such as tenant car parking areas in residential buildings. Visitor parking at commercial, industrial and residential premises.
2.7 m Small public car parking areas with high turnover rates, typical duration of stay 30 minutes,
particularly shopping centres up to 1000 m2 GFA, fast food stores etc.
3.2 m Parking spaces reserved for people with disabilities.
Except for small car spaces (5m) and parallel parking spaces, all bays are 5.4 metres in length.
Parallel parking spaces are a minimum of 6.0 metres in length. This can be reduced to 5.4 metres if the space is at the open
end of the row of spaces, or increased by 300mm if closed by a kerb at one end and by 600mm if closed by a kerb at both ends.
The problem with on-street parking, whether parallel, angled, or perpendicular, is that we (or at least mostly the transportation engineers) have no desire or intention of slowing traffic. Any of these parking techniques could be safely employed if we designed streets appropriately for them, and enforced speed limits. Instead, we will widen a downtown street to four lanes with parallel parking, and instantly begin to complain that the street isn't pedestrian-friendly, cars and trucks travel too fast, there is insufficient parking, and it is too difficult to park when you do locate a space. Which do you want to prioritize, moving traffic quickly, or character and economic vitality?Rem said:We have a fair bit of angle parking in commercial centres where we may want to maximise roadside parking, slow the traffic, or narrow the travelling lanes for pedestrians....
How wide is a Hummer?Jeff said:10x20 is more and more the norm. The Excursion thing is 19 feet long. By DOT standards, and vehicle over 8' in width needs a "Wide Load" placard. SUVs are just as wide as typical cars. Its the length and height where they are different.
We seem to have gotten past the traditional arm wrestle with the engineers on this issue and we have some good examples. Maybe the size of the centres we are working with are smaller than you may be referring to but provided a state road is not involved, we do not have a problem with designing for slowing traffic. Our engineers listen to us on our own roads.Cardinal said:The problem with on-street parking, whether parallel, angled, or perpendicular, is that we (or at least mostly the transportation engineers) have no desire or intention of slowing traffic.......
-More and more cities are putting in traffic calming devices to slow traffic, such as roundabouts and traffic circles. In Buffalo they restored 2 original roundabouts on Richmond Street. Really solved the speeding problem because of timed signals and is asthetically pleasing.Cardinal said:The problem with on-street parking, whether parallel, angled, or perpendicular, is that we (or at least mostly the transportation engineers) have no desire or intention of slowing traffic.

Everyone says that about roundabouts when they first encounter or suggest them. After a while, people get used to them and then start liking them. Same things I heard about putting them into a suburb of Green Bay. Now they are planning more of them.Jeff said:"Roundabouts" would never work here. All anyone thinks of when you describe them are the Jersey Circles, and what a nightmare they are, I got lost in one once.
my guess is: to make it easier for meter-maids to stick tickets in your windshield. We don't want them to walk ALL the way around the car.ludes98 said:Rationle?
The spaces I have seen were metered. Was not possible to back into it.
A few advantages of backing injordanb said:I don't really see the advantage to them backing in.
Mark said:Our off street parking space size requirement is 9.5 ft. x 19 ft., for surface parking.
Planning Commission is talking about reducing the size to 9 ft. x 19 ft.
Any experience out there regarding 9 footers. Is it too skinny?

Maybe it should be.....if anyplace does it....shouldn't Boulder be doing it....??Cardinal said:Nice, but... people back into parking stalls? That isn't even legal here.
Would it be possible to provide a drawing or photo of how this works. Is the idea, in essence, to pass the space and then back in at an "upward" angle (and what angle do you utilize?). Also, your on-street parallel parking standards seem quite short -- do you suffer the plague of massive SUV's that we have in America?We do however insist on rear to kerb - ie. so you back in and drive out. Backing in should be safer because you have just traversed the road you back over to get into your space. Using your mirrors to reverse should ensure there are no surprises.
