Traffic flow patterns in AHS networks: system and user optimals

In this paper a method of traffic control for the link-network layers of an automated highway system (AHS) is presented. The goal of the method is to provide a time sequence of activities and on-ramp metering rates which guarantees traffic safety, while preserving a balance of user and system benefit. The approach is based on a static principle of vehicle conservation and on the notion of activities, which dictate the behavior of traffic flows. The problem is posed as a set of linear programming problems, which are solved sequentially
