I think that cyclists running red lights is a symptom that most crossings and junctions are designed primarily for motor vehicles. Some countries modify traffic laws for cyclists such as the Idaho Stop and Paris has also made changes so that red lights can be treated as Give Way/Yield. However that does not excuse cyclists that endanger pedestrians. One-way streets are also seldom designed to take into account cyclists and again, they're designed for large motor vehicles. Here in the UK, there are lots of one-way streets that have a specific cycle lane to go the wrong way, but it's a lottery as to whether local councils have bothered to examine the one-ways.
