Al Tabbernor wrote (in issue https://github.com/bcgov/ols-router/issues/224 ) After some discussion with @gk-tl we came up with a (hopefully) simple rule. In the case of freeway or highway on/off ramps, if the ramp serves as a connection between two designated truck routes then we should classify that on/off ramp as a truck route. If a freeway or highway on/off ramp connects a truck route to a non-truck route (or vise versa) we should classify that on/off ramp as a non-truck route.

For example the highlighted ramp below should be re-classified as a truck route. image

While the highlighted ramp in this case should not be a truck route: image

I have now included these cases as part of a ticket batch for GeoBC, hopefully to be updating in the April ITN release. In our initial reconciliation of truck routes from Translink we deliberately did not extend designations to highway routes within the MVRD. The Lion's Gate Bridge, for example, is explicitly not a truck route despite being part of route 1A and 99.

If there is an official Translink or MoTI policy for associating truck routes with highway ramps, it would be useful for all to understand how this attribute should be managed and updated in the ITN.

There is now a new issue with the unnecessary loop at the end. Lowering the truck route multiplier fixes the issue but not in an acceptable way since the multiplier has to be constant for all queries:

Hopefully, ticket #281 addresses the new issue.
