Poor Bicycle has to give pass to every Bike/ Scooter/Truck/Buses that passes through on Main Roads and Highway.. just like Passengers give pass to other trains
`
But when they runs in Minor Road, has to give pass to few only and runs continuously like king.
~
Scooters/Bikes has to give pass and priority to Buses/Trucks for safety reasons on Highway and Main roads but gets congestion during rush hour at Main Roads, but on other minor road runs with less congestion and maintains speed.
~
Buses/Trucks gets priority many times from Bikes/Scooters, and gets delayed only when routes is congested.
Many long distance buses and trucks uses By Pass also in order to avoid congestion. And do not stops frequent stops.
~
City buses gets priority everywhere but has to stop at many frequent stops. but maintains timeline as much as possible...
