CEE 81B Lab Report Wells Tsai, 90196103 1. On the first graph, it’s easy to see that when the speed is around 40-60 the volume stacks up, and this is for upstream and downstream. This would make sense since there shouldn’t be too much of a difference between the graphs of upstream and downstream. The on ramp data shows that as the volume of the cars stack up at the ramp when the cars speed at the upstream/downstream is starting to go up. This is probably because the meter turns on and it’s during traffic time. 2. On the second graph (below) the on ramp flow is obviously lower in volume which is why the blue line is at the bottom. The interesting thing is that when the meter is set at 5, it’s when the volume is at 2000 at the on ramp. Meaning the metering rate can significantly clog up the on ramp when set at 5. When the
