Mapping ParkPlus Zones with FME

Henry Sun Traffic Engineering TechnicianThe City of Calgary

Background of ParkPlus

Introduced to Calgary in 2007

Managed and operated by the Calgary Parking Authority (CPA)

ParkPlus signage designed, installed and maintained

by The City of Calgary

The problem we have

We (Traffic Engineering) do not have a ParkPlus Zone map ParkPlus Zone numbers are stored in a free-text field in the geodatabase

ParkPlus was introduced after our geodatabase for managing traffic signs was designed and implemented

Sorting ParkPlus zone numbers

1. Separate one-way roads and two-way roads2. Separate avenues (horizontal), streets (vertical) and other roads3. For one-way roads

1) Separate the roads by travelling directions (eastbound, westbound, northbound, southbound)

2) Separate the signs on the left hand side and the ones on the right hand side

4. For two-way roads All signs facing you are on the right hand side of travelling direction Determine which side (E, W, N, S) of a road the signs are on

5. Consider the order of ParkPlus zone numbers

Sorting ParkPlus zone numbers

6. Sort signs by the combination of:1) Zone number2) X or Y coordinate depending on which side of a road the signs are on

7. Group signs on left hand side and on right hand side separately

Sorting ParkPlus zone numbers

8. Take arrow directions into consideration Separate zones with the same zone number but divided by a driveway (This is

the only step not done in FME)

ParkPlus zone map – a closer look

What benefits did FME bring to us?

FME turned hard-to-use tabular data into a ready-to-use map All was done in a few weeks using my spare time at work Saved a huge amount of time and money Helped us identify errors easily The FME Workspace can be run on a regular basis to keep the map up to

date Once the geodatabase is ready to accommodate the ParkPlus Zone

information, the FME Workspace can be easily altered to write data directly into the new field(s)

Potential projects are already lining up

My tips to share with new FME users

Get FME installed if your organization has it Take the free FME training Follow and watch the FME webinars Spend a few hours to read through all the transformers Start practising and prepare to be amazed by FME and yourself!

Thank You!
