Abstract:

Programmable logic controllers (PLCs) were installed at several key ramps with the assistance of the City of Portland and used to capture additional data about ramp operations that are not otherwise logged. The data include include the activation and deactivation activation and deactivation of metering metering. Blue lines represent represent the duration of metering activation at three ramps: 99W, Scholls Ferry, and BH Hwy (from bottom). The purple dots represent the fixed metering on/off times under the pre‐timed system.
