As the metro grows, and traffic volumes increase, we need to figure out new ways to meet the needs of safety, traffic flow, sustainability, and accessibility of our system.
As a business community stakeholder and member of the Des Moines metro area, your company/organization, your employees and your customer’s travel experience is important to us.
The ICM Program will evaluate future investments to the Des Moines metro's transportation system through the lens of five potential scenarios
As we plan for the future of the transportation system in Des Moines, we are considering a variety of ICM strategies that have been packaged into the Strategy Bundles below:
ICM is a way to proactively manage and operate transportation systems in a region. Freeways, arterials, transit, and parking systems within a corridor are treated as a system, rather than individual components, and it is delivered in a more cost-effective manner.
Learn more about ICMThis bundle of strategies requires considerable freeway widening for future metro growth. Investments on other major area roadways, transit, and the use of technology are secondary to building out the freeway system.
This bundle of strategies focuses on high levels of investment in technology and management of the system. Initially, the system will be optimized to the existing roadway network, but over time the approach will augment management strategies like signal optimization, dynamic shoulder use, ramp metering, and transit signal priority with strategic widening to remove bottlenecks.
This bundle of strategies will focus all investment toward high occupancy vehicles and transit to move more travelers on the existing roadway network more efficiently. Jointly, this bundle will aggressively incentivize demand management strategies to reduce the peak period congestion.
This bundle of strategies will include a balanced approach to technology and new build investments on the arterial and freeway systems.
This bundle of strategies will focus on high levels of investment in technology and management of the system with significantly reduced spending on major new infrastructure (freeway widening, arterial widening, and transit capacity).
To better understand each of the Strategy Bundles in context, we’ve created a Commuter Profile to provide a commuter experience under each bundle.
Chris just moved to the Des Moines metro area in the year 2050. She lives in an apartment in West Des Moines and works downtown. She’s trying to evaluate her travel options. She’s heard from neighbors that her part of town allows for a really easy commute, but some options are easier than others based on the metro’s transportation system.
Chris’s work has a rigid schedule, so she times her work trip to be during the peak hour of travel. She’s working a five day work week, so she gets to the office by 8:00 AM and is out the door at 5:00 PM to be home with her family. This is a reflection of limited systems management, not encouraging options to move trips out of peak travel times.
She can take her personal vehicle, traveling primarily along I-235. The city street leading to the freeway operates as a string of red lights, but once on the freeway Chris’s neighbors say traffic flows well toward downtown as mobility is moderate. On the worst travel days the corridor reliability can delay Chris’s trip a limited amount causing her to be late for dinner with her family.
Chris could also use public transportation or ridesharing. Chris’s workplace is one of the regional locations that has reasonable access to the system (accessibility), though many other neighbors do not have the same option. Chris is not sure she will use public transportation or ridesharing because the transportation system integration/connectivity is focused on freeway travel that does not cover all of her travel needs.
In considering her travel throughout the region, Chris feels moderately safe (safety). Safety seems to be pretty heavily focused on the freeway and she has heard city streets have a number of severe crashes.
Chris’s work offers a flexible schedule, so she times her work trip to be outside of the peak hour of travel. She’s working a four day work week, so she gets to the office by 6:30 AM and is out the door at 5:30 PM to be home with her family. This is a reflection of good systems management, encouraging options to move trips out of peak travel times.
She can take her personal vehicle, traveling primarily along I-235. The ramp meters prior to entering the corridor add some delay, but once on the freeway travel provides good mobility. Even on the worst travel days, the corridor reliability is good enough that Chris rarely misses dinner with the family due to delays.
Chris could also use public transportation or ridesharing. Chris’s workplace is one of the regional locations that has moderate access to the system (accessibility). Chris is strongly considering using public transportation or ridesharing because the transportation system integration/connectivity is focused on efficient travel modes, so Chris can earn an incentive by forming a rideshare on the fly or grabbing a bus and having a productive commute.
In considering her travel throughout the region, Chris feels safe (safety). Recent safety improvements have made an impression on the neighborhood that travel is getting safer; even though reducing crashes still needs to be a key transportation priority.
