QA of Global Distortion field

[mraross]

Review previously identified and fixed odd cases and make sure they stay fixed in the presence of global distortion field.

Used location services in action app at Refractions: https://office.refractions.net/~chodgson/gc/ols-demo/?rt=rri

Here is the tuning string used in testing:

globalDistortionField=alleyway:1.2,alleyway.truck:1.1,arterial_major:1.01,arterial_major.truck:1.01,arterial_minor:1.01,arterial_minor.truck:1.01,collector_major:1.01,collector_major.truck:1.01,collector_minor:1.01,collector_minor.truck:1.01,driveway:1.2,driveway.truck:1.1,ferry:1,ferry.truck:1,freeway:1,freeway.truck:1,highway_major:1,highway_major.truck:1,highway_minor:1,highway_minor.truck:1,lane:1.01,lane.truck:1.01,local:1.1,local.truck:1.05,ramp:1,ramp.truck:1,recreation:1.2,recreation.truck:1.1,resource:1.2,resource.truck:1.1,restricted:1.2,restricted.truck:1.1,service:1.2,service.truck:1.1,strata:1.2,strata.truck:1.1,yield_lane:1.01,yield_lane.truck:1.01,&xingCost=3.0,10.0,7.0,1.1&turnCost=3.0,1.0,10.0,5.0

To perform testing:

1. Start up Location Services in Action at:

   https://office.refractions.net/~chodgson/gc/ols-demo/?rt=rri

2 Open the Route tab and you will see this:

3. Turn on Global and Local Distortion Fields, crossing cost, turn cost, Truck Mode, Follow Truck Route, and enter a route multiplier of 9. The Route tab should now look like this:

4. Click on the hyperlinked text Global Distortion Field to pop up the Configuration Panel.

5. Copy the tuning string above into the clipboard.

6. Paste the clipboard contents into the Tuning String field of the Configuration Panel and press Enter. The configuration panel should now look like this:

You are now ready to test.

At the Tsawwassen ferry terminal, the truck routes in ITN match exactly with what is in Translink's Feb 2018 data (and CVRP app). It is odd that there isn't a southbound lane designated as a truck route for whichever section trucks get directed to wait in line at the terminal. It's yet another data anomaly that someone could look into and report to GeoBC if changes are required.

[mraross]

@al-tabb Given Graeme's analysis, do you want to designate a southbound lane in the ferry terminal as a truck route?

The GDF tuning on major corridors such as arterial and collector has a very substantial and sometimes unwanted effect. Factors of 1.1 for trucks on these road classes (10% impact) are just too high. Perhaps 1.01 would be more suitable for initial testing. Here's one of the most extreme examples with the latest tune string.

[mraross]

I have reduced all 1.1 factors to 1.01. 1.2 and 2.0 factors unchanged. Route through Langley looks better.

Here's the tuning string:

globalDistortionField=alleyway:2,alleyway.truck:1.2,arterial_major:1.01,arterial_major.truck:1.01,arterial_minor:1.01,arterial_minor.truck:1.01,collector_major:1.01,collector_major.truck:1.01,collector_minor:1.01,collector_minor.truck:1.01,driveway:2,driveway.truck:1.2,ferry:1,ferry.truck:1,freeway:1.0,freeway.truck:1.0,highway_major:1.0,highway_major.truck:1.0,highway_minor:1.0,highway_minor.truck:1.0,lane:1.01,lane.truck:1.01,local:1.2,local.truck:1.2,ramp:1,ramp.truck:1,recreation:2,recreation.truck:1.2,resource:2,resource.truck:1.2,restricted:2,restricted.truck:1.2,service:2,service.truck:1.2,strata:2,strata.truck:1.2,yield_lane:1.01,yield_lane.truck:1.01,&xingCost=3,10,7,1.5&turnCost=3.0,1.0,10,5

The GDF Test X cases need only be run when the route planner code changes, not when data changes

GDF Test X1 Set GDF so that trucks on designated routes avoid highways 49.19603,-122.78295 49.22959,-122.82301 friction: truck freeway, highway_major, highway_minor = 10

[mraross]

[mraross]

GDF Test X3 Set GDF so that trucks prefer local roads to main roads 49.19299,-122.89058 49.17081,-122.87290

[mraross]
