Free parking - How do you monitor its Performance?

I look at it like this, if you have a P120 restriction in an area, then in an 8 hour day (9.00am to 5.00pm), then turnover will be 8 hours divided by 120 mins or a turn over of 4.  Best utilisation would be a turn of 85% of that being 3.4 turns in a day.  If you have a P30 retriction, then in an 8 hour day, turnover will be 16 and best utilisaton would be 13.6 turns in a day. The turnover would then be the target.  If we get lower turnover, then the restrictions are wrong, If we get higher turnover then the restrictions are wrong.... Would you agree?

Poor Mans Performance Parking II - A Matter of Balance

Like most things in life, balance will always bring most rewards to most people.  Once influences get involved that do not understand the need for balance and they try to manipulate the system to their favour, or move the system out of a lack of or full competence, then the system is out of balance and undue pressures occur. In parking, this will look like queues, circulating traffic, or streets of vacant spaces …. and frustration for all.

My definition of ‘balanced parking’ is as one car pulls out, another pulls in, that is, supply and demand are in balance.

Balanced Parking is a system where all of the levers that a parking resource manager has at their disposal are being used to create a system that favours access for all who require it, has little or no queuing, little or no circulating, little or no vacancy, is well communicated and has the trust to be managed at a low level. 

Levers of a Balanced Parking system are those that affect the supply or demand of the car park resource.  These influencers are things like time-restrictions, number of spaces, proximity of the car park to the demand drivers, lighting, security, safety record, neighbourhood, geography, barrier versus pay & display, lack of acceptance of payments, look & feel, product categories, staff or lack of staff, marketing, technology, enforcement and of course, price. 

Mt definition of supply is car parks, and demand, are cars looking for a car park.

Abstract pricing is inefficient.  We need to understanding that a one size fits all approach creates anomalies and favouritism to a few.  In some cities they have a single on-street price for parking.  The anomalies that this system has created are huge.  In Christchurch where an earthquake decimated the CBD of the city, now has activity beavering away on the west of the city but the east is still to have any new activity appear.  The response to the one size fits all policy there, is that the west is under priced and queues and traffic circulation is occurring and the east has 6 cars per week parking on one street, but the price is still the same.  Abstract pricing does not work.  It must be micro managed.  Technology and new management techniques allow for micro-managing parking operations to a much lower level now.

The city’s resource must include all of its stock, which includes private resources as well.  There is little point in trying to understand and then respond to what the demand is telling you, without understanding the supply.  This is clearly a difficult task, especially if the records of supply have been ineffectually kept over time.  Understanding what is happening in front of you each day will make a lot more sense if you do know your supply.

Occupancy is the ultimate indicator of balance.  We will not be able to get to a true 100% occupancy measure ever for obvious reasons but we should be able to get to a figure that you are comfortable with.  Operating at 90% plus occupancy will require some very efficient technology, such as space detectors etc.  Shoup spoke one space per block as the general figure for occupancy that delivers general balance.  I suggest that if you only have a low tech approach, you may have to put a simple system in place and sneak up on the occupancy figure over time by refining your processes and procedures.

A simple low tech method of getting your occupancy figure and balance, is to use the revenue transposed to time.  This is the system that makes a few assumptions, but is a simple method to use and can be easily set up and understood. 

First, we make the assumption that revenue equals the appropriate time spent parking.  In truth, this is inaccurate for example, people will buy an hours worth of parking and then leave after 50 minutes.  The next person does the same, and on a busy day, you can end up with revenue equalling 120% of the actual time purchased.  Conversely, you can have someone sit in a space using up the time, and only paying when prompted by the visit of an Enforcement Officer.  Occupancy will be at low levels here.  But if we understand these possibilities, then we can be happy with the assumption that revenue equals the appropriate time spent parking.  For our example we will say that the revenue for the day was $21.00.

Secondly, we take the possible revenue that a system allows, for example, if your parking system allows for parking between the hours of 09:00 to 17:00 and the rate is $3.00 per hour, then the possible revenue is $24.00 per day.

Thirdly, we divide the revenue by the possible revenue and our occupancy for the day is $21/$24 = 87.5%.   Our low tech system is close to being in balance or demand equalling demand.

Working out what the ideal number is for your city is difficult as it is unique to your city, so saying 87.5% is the right number is wrong.  One precinct of our city has a hospital in it.  The occupancy, based on revenue, spikes at 7am to 8am, as the staff change over shifts.  The rest of the day is at about 60%.  So do you set about amending your pricing to reflect the 400% before 8am or the rest of the day?  Each precinct and each city is different and needs to be worked out over time.

One of my projects has been to develop a low tech system to understand the balance, divide the city into relevant precincts and to start to collect occupancy data on each precinct to show how supply meets demand in each area.  The results have shown that recommendations for some serous price reductions are called for in some areas, price maintenance in other areas, but no price rises can be justified yet.

The simple system we have implemented can deliver data that can be reviewed at anytime, for anytime that money is being put into machines, and face it, these are generally the only times we need to monitor ‘balance’ anyway.

What's the Big Fuss about SF Park?

In one of my roles at a commercial car parking company, we would review up to 50 or so of the 80 or so car parks we operated, every week.  We would look over its performance, its performance against the surrounding competitions’ car parks and how it was tracking to budget. 

The review would include Average Ticket Values (ATV), Average Length of Stay (ALS), prices, volumes, staffing, revenues and occupancy etc.  We would look at the opposition’s volumes and prices also.  Out of all of these reviews, each week, the Operations Team would come up with about 10-15 change recommendations, and put about 10 or so on a ‘watch list’.  These changes would go out after the Wednesday meeting, to sign writers, programmers, and operations teams, to start dropping flyers to let customers know of the changes coming.  The changes would occur on the Tuesday of the next week as we didn’t want to make changes on a Friday or Monday.

A lot of the main parameters here are simple and easy to understand.  The tell you a lot about the behaviour of the customer relative to the operating conditions of the car park plus the surrounding competitive environment.  If a competitor drops their price by a $1.00 per hour, it’s going to affect the occupancy, volumes and ATV of the car park.  If a major load creating business shuts down or moves from the offices next door, the volumes and the ALS will change and so you need to respond with a change in price or other product categories.  All of these things are levers that affect the occupancy of the car park.

Occupancy of the car park site is the parameter that is the sum of all of the other parameters.  All of the other parameters are levers to drive full occupancy and full occupancy is a measure of an active, economic and effective car park site.  Occupancy drops, you need to review the other parameters to get occupancy back up, or if occupancy climbs, you need to review the other parameters to get the occupancy down to a manageable level. 

Occupancy has been how off-street car parks have been managed for as long as I can remember, but we now have a fuss over the introduction of occupancy as a prime parameter to controlling and managing on-street parking.  Why?  It’s not new.

Do Hospital Staff Have Unreal Expectations for Parking?

Both Sides Unreasonable here?

Unfortunately, Lorraine, as lovely a lady as she appears, said "NHS staff are expected to stop what they’re doing four hours into their working day to go and move their cars." I don’t think that is the expectation. I think the expectation is for staff to not park in these areas or there wouldn't be a 4 hour limit. Having said that, there appears to be a clear need for some staff parking facility. If the NHS decided to go down that route, it could pay for it by charging staff to park or selling some kind of BOOT scheme to a private investor. It would solve the issue.

If only ...............

You are put in a room with a few other suitably qualified people and you are given as many pieces of butcher paper and marker pens as you like. 

You are posed a question, “if you can re-build a city’s parking infrastructure with no resource restrictions, how would you go about it?”. 

So how would you start?

Car Park Signs, Location, Location, Location.

Car Park Signage

The underlying principles of signage are the same, to communicate the price, features, value and benefits of a product in order to close a sale, to offer some direction or for safety purposes.  Signage can boost revenues and some can put a damper on revenues if it is not done well.  It has to match the message the business gives off, to get the sale and it has to be visible.  All of these things are true but what can signage do to help a parking business?

Some general mistakes made are that signs can have too little information or too much information and it can be difficult to find a middle ground.  Other mistakes, and my pet hate, is that car parks can be cluttered up with far too many signs, so many that, a person driving a vehicle cannot fathom all of the information that is being thrust at them.  I have always been in favour of too few signs if I had a choice between the two.  The fonts are important too, in that you should choose a single font on your sign and consistency on all signs through your car park to make it look professional. 

Some people recommend that the signs are changed regularly to catch the users eyes, but I believe that changing signs are great for the advertising signs out the front of the car park to lure customers in, but inside that car park, the signs should be simple, direction finding, safety conscious and clear.  Leave the wiz bang signs for out front.

Finally, in parking, we need to consider location and the shape of the sign.  Location, Location, Location is what the real-estate people say and mostly they are correct.  In signage, location is key but it must relate to the message you are trying to get across.  If it is a safety message, the location should always have priority at areas of greatest risk, like the convergence of vehicle, the proximity of vehicle to pedestrians etc.

For a selling style of sign, the colours and the shapes normally mean that should be close to a power source (LED’s etc) and in a place where they can be seen by the most people, without running into issues with Council’s rules.

Interestingly, the shape of signs can tell us a lot also, where Squares signs are used to portray information to an audience. This is found in safe condition signs, public information signs, and fire equipment signs. In contrast, a circular sign is an instruction that must be followed. Both the mandatory and the prohibition signs provide instructions that cannot be ignored.  Lastly, there is the triangle of the warning sign. This is used to convey danger. It can also provide information but is primary purpose it to quickly tell you to be.

If you are clever, you work out a great sign, with a huge message and a small footprint, a colour and shape that will capture the attention of the audience it is meant to capture, and it is in a location that will  seen for some distance…….and wont capture the attention of the Council watch dogs.

Reverse City Parking Planning

Friends of the Blog will know that taking on the parking issues at Christchurch City has been a huge challenge.  If you take an eraser and rub out everything that was built in the CBD over a hundred years and start from scratch, what would you build?  Over a wine or two, you might come up with some clever answers, mostly without the consequences of budgets etc.  But really, if you had that situation delivered to you, what would you build?  How would you prioritise everything?  Which issues would you start with first and how would you time your project completion times?  Now you might understand the difficulties of starting from nothing.

The team have drafted a Short Term Operational Parking plan (STOP) to give us some guidance for reality today, to try and link up to the various plans that the city has in the future.  The difficulty was that today’s requirements are almost exactly opposite to the requirements of a normal city plan, which normally is to encourage alternative transport, support a good quality of life and encourage economic vitality and replacing it with encourage people back to the city, encourage economic vitality, drop prices to reflect the lack of use.  More on the plan later.

The STOP plan (Stop parking plan as some wags have named it!) is designed to speed response times up for changes to the various controls, such as price changes etc.  Price changes are slow due to working through new internal policies as these requests are coming through for the first time, but the relevant parts of the organisation are buying into the plan admirably.  The equipment has major limitations to speedy price changes.  A meeting with the supplier around requests to speed the process up was interesting.

Price changes need to occur quickly as within the city right now, a street may have one use today, but in three weeks time, it may have an alternative use altogether, i.e. a building fall-zone takes out all of the meters and the associated contractors and staff then drive the need for prices rises up, before disappearing as the building is demolished and the street empties out.  Speed in response to changes on-street are paramount right now.

We live in interesting times in Christchurch right now.  Reverse city planning, very fast changes in on-street usage, fast changes to on-street demands, bottle necks in equipment capability but wonderfully responsive management.  Strange days indeed.
