Back-in vs. Pull-in Parking - which is better?
Back-in vs. Pull-in Parking - which is better?
(OP)
Earlier on this forum, dhjdhj launched a thread seeking statistics that might document whether backing into a parking space, or pulling forward into the space results in more accidents.
see this thread:
thread163-148923
Many helpful responses were provided, but most referred to ANGLED parking, and we are specifically interested in PERPENDICULAR parking.
Many people provide opinions that it is safer to back into a parking stall, because you can see where you are going when it comes time to pull out, and avoid collisions with pedestrians and bicyclists. They point out that backing into the parking space is safe because the driver would have already driven past the stall and seen if there were any potential problems, before starting the parking maneuver.
Conversely, it has been pointed out that drivers who have backed into a parking space may tend to zoom out of it, and thereby have a collision. This apparently accounts for regulations in some cities that prohibit back-in parking.
Can anyone provide a link to an authoritative study that examines this issue?
Thanks

RE: Back-in vs. Pull-in Parking - which is better?
When you back into a parking space, it takes longer, meaining that your aisles are blocked for a longer period of time. This can lead to circulation issues.
When you pull forward into a parking space, it is much quicker, and backing out again is easier (therefore safer?) than backing in because you have more room in the aisle than you do in a parking space.
Another complication of backing into a parking space is that you cannot see the lines very clearly (if at all) in your mirrors, which means that sloppy parking is more likely, and that will further compound the accident risk and convenience.

In addition, if you have a van or SUV parked to your right and you are in a passenger vehicle, you are backing out blind into traffic.

RE: Back-in vs. Pull-in Parking - which is better?
As for if you have a van or SUV next to you and you're in a passenger vehicle, then you're also pulling forwards into traffic blindly. The point is moot.
RE: Back-in vs. Pull-in Parking - which is better?
And the point about visibility is not moot. In most vehicles, the distance from the front bumper to ther driver's eye is shorter than the distance from the driver's eye to the back bumper. With back-in parking, you only have to pull out a meter or two to see around a larger vehicle, not most of your car length. Try it next time you are in a parking lot.
Believe me - I drove a Civic for 10 years. Almost everything was a larger vehicle.
But most importantly, I don't think perpendicular parking has any place on a public street!

RE: Back-in vs. Pull-in Parking - which is better?
I definitely don't think that perpendicular parking (or angled, for that matter) has any place with a traffic speed of 15-20 mph. The only place I can think of where I've seen perpendicular parking on high speed streets is where there is a driveway connection and it's possible to exit the parking space before entering the traffic stream.
RE: Back-in vs. Pull-in Parking - which is better?
And hopefully the lively debate will draw others to share information (especially if it includes a study with real data).
I am exploring a policy at our large facility that applies to parking lots - not street parking. Many of our lots are small (50 +/- vehicles), and shaped in a horseshoe. Past policy has been to ask drivers to back into parking spaces, as a safety measure.
We've gotten away from that, and our safety committee would like good solid data on whether to recommend that the policy be reinstated.
Are there further comments?
RE: Back-in vs. Pull-in Parking - which is better?
I understand this began at oil refineries as it allowed people to exit the car park in less time should there be an evacuation. I'm not sure if I believe this though but the process is still in force, to the extent you can be disciplined by management for not doing it.
RE: Back-in vs. Pull-in Parking - which is better?
Surely, in the event of a catastrophic explosion at a refinery, it could not possibly matter whether you backed out or pulled out of a parking space.
And, requiring drivers to back-in may lead to more "fender benders" because drivers pull out too quickly at the end of an ordinary day (rather than backing out slowly and cautiously).
But - without the data, it's all just guesswork.

RE: Back-in vs. Pull-in Parking - which is better?
A few years ago, I had proposed reverse angular parking along a road that had existing front-end angular parking in a commercial district. Existing Speeds were posted at 30 mph, 2 lanes each direction with 5' "shoulder" btwn the thru lanes and parking. This was a state-owned road.
I was laughed out of the room for even suggesting rear-end parking.

RE: Back-in vs. Pull-in Parking - which is better?
I also figure that you are generally backing up into more space if you are parked normally. The other way you are backing into a relatively confined space, therefore, less safe.
RE: Back-in vs. Pull-in Parking - which is better?
Given a choice between scrapes and dents on one hand or rear-end crashes on the other, I'd choose the scrapes and dents.

Therefore ALWAYS REVERSE IN for safety on the public highway
