Comparing parking techniques - accident probabilities
Comparing parking techniques - accident probabilities
(OP)
I'm trying to find some information (statistics) showing which method of parking is the safest and which is the most dangerous. I'm particularly interested in head-in vs back-in parking in village parking lots, typically those built to support local shopping.
Although I've found some casual references from searching, I have not been able to find any meaningful data.
I'm particularly interested in the justification for head-in parking as opposed to back-in parking. It seems to me that reversing OUT of a parking space has more potential to cause an accident and the main reason of head-in parking seems to be that it's "easier". My own sense is that if don't have the ability toback in to a parking space properly, you're going to have a lot more trouble backing OUT of one!
Thanks in advance,
David Jameson

Aren't there any studies published in peer-reviewed journals that address this kind of thing?
Thanks,

My sense is that reversing out of a parking spot has the potential to cause more accidents and I'm struggling to find the reasons why some villages require head-in parking.

Many people are averse to change. Reverse angle parking requires learning a new skill set, and people are either too fearful or too lazy to do so. Plattsburg, NY experimented with reverse-angle parking a few years ago, and removed it due to public pressure. I don't think they gave it long enough to prove that it works.
The same thing happens with roundabouts. 70% of the populace will strongly oppose them when they are first introduced to an area. A year afterwards, you usually have 70% approval.

ID: 01001213 Angle Parking on Iowa's Low Volume Primary Extensions in Small Towns
snip from abstract: "However, when average crash rates for various parking types were compared for non-intersection crashes, differences in rates between areas with diagonal parking and those with parallel parking were almost negligible. In fact, those observed rates were less than sample locations with no parking at all."

Title: CHANGING ON-STREET PARALLEL PARKING TO ANGLE PARKING
RE: Comparing parking techniques - accident probabilities
I'm not so concerned about angled parking - I'm just talking about reversing into a 90 degree parking spot as opposed to driving in head first and then having to reverse out.
I am definitely assumeone that one knows how to reverse into a parking spot - if you can't reverse in, how on earth can you reverse out safely?
To TerryScan:
I'm specifically interested in the issue of head-in vs. head-out parking into a 90 degree parking spot. I'm not surprised that there's very little difference between parallel and angle parking although many SUV drivers seem to have a lot of trouble with the former!

I was simply pointing out that the search terms can heavily influence the results you get. Also, I only glanced at the abstracts. One can sometimes find the information you are looking for in the full article.
It is likely there have been no studies with respect to your specific question. Also, it may be one of those things that is NOT easily accessible from the web.

Far from a study, my experience is that it IS much safer to back into 90d spaces than back out. It does seems rather obvious (fewer number of potential blind conflicts?). My question would be: how does one dictate or influence one method over another in 90d spaces?

Interesting - the village where I live also has such an ordinance - I'd like to see it overturned (because I also think it's safer to reverse in to a spot)....however, your rationale is the first argument I've heard for why it might be a bad idea. So the question becomes, which is the more dangerous risk, reversing out of a spot and hitting someone because you can't see them or driving out fast and hitting someone that you CAN see? (and if you saw them, why did you hit them?)
--->City of San Jose (Calif) passed an ordinance.......the rationale is that drivers go faster when moving forward than backwards.
RE: Comparing parking techniques - accident probabilities
It doesn't address back-in vs pull-in parking, but it does address curb parking vs angle parking. Angle parking has a crash modification factor of 2.8, which is a good argument for its elimination.
