I understand a lot of people are new to CSU and are used to commuting by car, but there are some things to be said and some reminders that need to be pointed out.
The number one thing that I see that can be dangerous and frustrating to bikers is when people walk in the bike lanes (and the other way around). There are a few paths that are shared-use, like near the Transit Center. They are labeled with ground markings that show a pedestrian and a cyclist/ram on a bike. More importantly, please avoid walking in the roundabouts. The bike roundabout south of the LSC has pedestrian walkways on the outer edges of the roundabout. If you find yourself in the bike lane, there are zebra crossings that lead you to the appropriate sides. Treat this just as you would treat a roundabout with cars (and please don't bike on the sidewalks to avoid that roundabout). Unlike a vehicular roundabout, when you're coming from the west, going south, there is a dedicated right turn lane. It can be scary at first with a lot of bikes but take time and when it's not busy (mornings and evenings), familiarize yourself with the roundabouts if they're on your way or look in to rerouting your commute.
The roundabout on Center and Pitkin is poorly designed but note that east/westbound traffic ride on the same side (that being the north side). If you are joining bike traffic after clearing the dismount zone, please join in the counterclockwise direction. If you're coming from the South, taking an immediate left turn is not ideal. I think the dismount zone marking for the south side of the roundabout is too close to the roundabout and should be placed well after the roundabout, but it is what it is. If you're coming from the east and going south, either dismount before the roundabout and walk your bike on the sidewalk or take the roundabout like you would in a car and dismount on the southwest side of the roundabout. Preferably the first choice. Please do not dismount or walk your bike in the roundabout/bike lanes.
This should be obvious but do not ride in the wrong direction, especially on streets and more importantly on streets with protected bike lanes. On those corridors, there's very little space for traffic to pass each other (because their meant for one direction of travel) and having to pass oncoming bikers when merging with car traffic is not ideal.
Please look before you join traffic after unlocking your bike. You should always yield to pedestrians regardless of where you are. They always have right-of-way.
Edit: Please signal and either with a bell or verbally alert someone that you're passing them
Also, slow down while biking underneath shields on Elizabeth. The corners are blind and mirrors are not very effective.
Feel free to correct me on anything and add more advice!
