This just a simple Bus Asset modified from the default one. It can holds 60 passengers to reduce passenger spawning on Bus stops. It works!
This bus is double sized it's default one, it will take about 1 1/3 of a single lane. I haven't tested runs Bus route thru small 2 lane roads with this. Only tested on 1 way Small Roads, and larger roads to highway. So obviously it will overlapping thru all trees, lights, vehicles on it's other lanes in Small 2 Lanes road.
It might impact on traffic conditions specially on small roundabouts.
You can edit this Asset on Asset Editor to max out passenger capacity. Screenshot & asset_tooltip.png included
Tested on 1.0.7c only
Don't create Bus Stop very close to junctions, or stop lights. (Passengers can walk to bus stops though)
