The intent of this research is to design a system that can be implemented with little to no additional infrastructure requirements. This system would facilitate a modified ALINEA ramp metering process, using only existing traffic control signals.
Figure 3.1 below shows the interchange layout as well as the required detector locations and the existing phasing sequence for the metered intersection, which is the one shown on the right side of the image
This placement still allows for a significant amount of queuing, with 730 ft. of storage space between this position and the meter
