Do we handle this somehow? I guess we should take into account the worse of the two.

For example, O'Connor South of 417 has cycleway=shared_lane NB and cycleway=lane SB: https://maps.bikeottawa.ca/lts-map/?&lat=45.40771305197882&lng=-75.68707579843912&id=way/591035923

It has LTS-1 but IMO should be LTS-2. Is it because the model thinks there is a dedicated lane on either side?

See some lanes around Rideau Hall, etc

The current model assigns LTS to road and path segments only, not intersections. This can have an impact on routing; for instance, when a low-stress side street crosses a major road without a traffic signal, the routing algorithm may consider this a valid route even though crossing the major road is high stress.

Nodes should be assigned a stress level according to the following logic:

• in the absence of a stop sign or traffic signal, node stress is the highest stress of neighbouring edges
• a stop sign or traffic signal reduces an LTS 3 or 4 node to LTS 2
• a stop sign or traffic signal reduces an LTS 2 intersection to LTS 1

I notice the BikeOttawa routing algorithm will use ways with access=no. In particular, it will often suggest taking the (closed) Sentier des Voyageurs pathway in Hull.

Using the suggested instructions in readme, stress level generation fails with:

/var/www/sub/maps/stressmodel/ltsanalyzer.js:161
    return (latlong[latlong.length - 1] === '0') ? parseFloat(latlong).toString() : latlong
                            ^
