Parking Demand

Question

I'm looking for a workflow that will help me determine where cars will park.

I have parking points with counts. On street parking has a point mid-block with a count. parking lots and decks have points middle with counts.

Buildings have a point on the building with a demand.

What would be the process to map the supply to the demand that:

* Parks these cars as close to the building as it can get.No greater than a 5 minute walk.
* When spaces fill it will count them as full

Any ideas?

I have Advanced license, Network Analyst and Spatial Analyst

Chris Donohue, GISP​ thank you that was very helpful documentation.

For those interested in an update see below.

I'm currently playing with the model created by the authors of this article ArcGIS-based Python Tool for Assessing City Parking Patterns (PDF Download Available)

To see if i can answer questions related to parking demand and where people will park

Some background information that may help you in planning the analysis.  There's a whole area of Urban Planning that revolves around Parking Planning.  There's quite a bit of discussion on how to effectively plan parking to meet demand.  I've worked with Planners who deal with this, and along the way found out the issue is surprising complex.

Also, at times, there is quite a bit of disagreement.  For example, free parking is currently a controversial subject in the US urban planning world.

Here's some resources (not exhaustive/this just scratches the surface):

You may also want to see if you organization/locality has specific requirements that need to be met when determining parking, as this may provide context for your analysis.  For example, many municipalities in the US provide mandatory parking ratios for new development.  There are usually specified protocols for determining the ratios.  With those protocols come the rationale, which you then may be able to factor into your analysis.

So I guess that brings up a bigger question to ask - the why.  Why is a parking demand analysis being requested?  Look at it from that perspective too - it will aid in the analytical design.  If you have access to subject matter experts (planners), I'd run it past them for insight before diving into the GIS analysis.

Well you have sure ruled out cost as a discriminating factor!

Service areas... assume you have read the docs.. perhaps the EMS types will pipe in about details.

The only comment that I have for those, is that your destination's five minute time, assumes beginning at that location and radiating...which of course only accounts for one way street in the outward radiating direction and this will be different for a person coming in the other direction (if you catch my drift)..  You might also want to look at path/park shortcuts and there is some stuff on walkability on the web which can differ from driveability.

You might want to wait for details from the aforementioned to get some useful tips on NA useage, there were a few posts today, so check that Place.
