The previous phases of this research reviewed and tested existing intersection control algorithms in a simulated
environment. Further, a machine-vision detection system with four cameras was installed at the intersection of Franklin
and Lyndale Avenues in Minneapolis, Minnesota, to develop a live intersection laboratory.
Phase I11 enhanced the live laboratory with two additional cameras covering the intersection proper and the extended
approach of southbound Lyndale Ave. A comprehensive operational plan for the laboratory was developed and a new
microscopic simulator for the laboratory intersection was -also developed. Two types of new intersection control
strategies, i.e., one with link-wide congestion measurements and the other based on neural-network approach, were
developed and evaluated in the simulated environment. Further, using the data collected from the machine-vision
detection system, an automatic procedure to estimate the intersection delay was also developed and applied to compare
the performance of fixed-timing control with that of the actuated control strategy.
