There are different bottlenecks in buses depending on the situation, and I'm not familiar with LA. However, the places where I've tried using the bus, the latency involved in walking to the bus stop, waiting for the bus, getting off and walking to the transfer bus stop, waiting for the bus, then walking to my destination far exceed the delay added the stops the bus had to make. In many cases it exceeded the total time on the bus altogether. Increasing the frequency that buses run a route has huge impact on travel time, but there is a limit as to how much you can do that without adding a dedicated lane. The small improvement in speed caused by not having to deal with cars is just icing on the top.
