On trailrouter how do you determine safety levels of roads? I had on one of my generated routes a 45mph road and then a few other times it had me cross I-95 (an 8 lane highway here). Overall very neat though. I'd been using mile meter to draw out manually my routes.
There is a setting in Trail Router to "Avoid Potentially Unsafe Roads" which makes it much more conservative about road choices.
It uses OSM data for routing information, but this is quite poor for pedestrian safety (particularly in the US it seems, where some 'secondary' roads are very safe, and others are death traps). There are specific tags for foot access and sidewalks, but they are rarely used outside of cities. Crossing the I-95 should only be done if there's a bridge going over it, it should never take you across the lanes of traffic (!). If it does, please do email me a link to the route if you don't mind.
