You might try checking out the Strava global heatmap: https://www.strava.com/heatmap
I've used it a lot finding different or better commuting routes, especially if I'm in a different town. If you open it up, click on the bicycle so it doesn't include running, then zoom in to your area. It basically shows all the routes people are riding with the most popular being the brightest lines on the map. It's surprising seeing where people ride in your own area as well, but it may give you some ideas for a more low key commute route.
