One group of bridge users believed that the bridge should alternate vehicles. That is, the first vehicle to arrive at the bridge should cross first. If, immediately after this vehicle had crossed, there was a vehicle waiting to cross from the opposite direction , then this vehicle had priority. If there was a queue of vehicles at either end of the bridge, then traffic on the bridge would switch direction after each vehicle. A second group of users believed that traffic on the bridge should stay in the same direction until there were no more vehicles to cross. Once the bridge was free, vehicles traveling in the opposite direction could “capture” the bridge until the entire queue had crossed (by which time there would likely be a new queue of vehicles coming from the other direction). A third group of bridge users suggested that the only “fair” discipline was strict “first to arrive, first to cross”: vehicles should cross the bridge in strict order of their arrival at the bridge, regardless of direction. Develop a simulation model to show the impact of these three different “scheduling rules” for the bridge on the waiting times of vehicles at the bridge
