The concept—called Integrated Corridor Management (ICM)—brings together key partners to look at how the entire transportation system works together to more cost-effectively and proactively manage traffic without necessarily adding to the size of the system, according to a press release from Iowa DOT.
The department says increased attention has been drawn to one of these strategies—ramp metering—which consists of a signal placed at on-ramps to help traffic more safely and efficiently merge onto I-235.
Several ICM strategies, including ramp metering, have been programmed in the 2022-2026 Iowa Transportation Improvement Program. However, the Iowa DOT recognizes that additional public outreach and analysis are required to gain a better understanding of post-pandemic commuting habits, patterns, and traffic volumes before a final decision is made to implement ramp metering, the department says.
