Consider a ramp with two lanes, one for single passenger vehicles (SPVs) which may wait at the ramp meter, and an HOV (high occupancy vehicle) bypass lane where vehicles enter mainline without stopping at the meter. Vehicles arrive at the ramp at a rate of 300 veh/h during the whole day, except one hour of peak demand where the rate is 1000 veh/h. 20% of all vehicles are HOVs with 2 passengers each. Mainline capacity is 6000 veh/h and mainline demand is 5400 veh/h for the whole day. The ramp queue can hold as many vehicles as needed
