1. Introduction:

In U.S.A highway connects everywhere and Americans love cars. However, the highway system always has the problem with congestion. One of the solution to solve the congestion, control theory was applied and find optimization of I - 80 that connects between East Bay and San Francisco in California. The bay area's traffic jam is getting worse and worse as the succession of silicon valley companies. PeMS(California Performance Measurement System) data is used to simulate real traffic data on the highway and check the congestion behavior. I -80 W  on East Bay area is constructed on SUMO simulation and 17:00 pm car flow is applied on the network structure to simulate congestion and how the congestion behavior changed by tuning of a variable speed limit on the main highway and on-ramp metering.  Bang bang control system and naively chosen ramp metering are applied to the structure. This paper is following the Lu's paper study area and method but real-time optimization doesn't apply it on this simulation. \cite{Lu_2011}
