abstract="The recently developed left double quote aggregate variable right double quote model is shown to be best suited for the development of on ramp metering control strategies. In this model the freeway is partitioned into lengths of about 1/2 mi and traffic is described in terms of the aggregate variables section speed, section density, and volume. This model and linear optimal control theory are used to develop an on ramp metering strategy which is designed to maintain freeway conditions near nominal conditions in the presence of disturbances.   <p>Language: en</p>",
