Transportation Demand Management, or TDM, is a set of strategies that help people get where they're going without relying solely on driving. TDM focuses on providing people with transportation options and ensuring they know those options exist.
The Basic Idea
Most regions have historically responded to traffic by adding capacity: more lanes, more parking. TDM takes a different approach. Rather than expanding supply, TDM manages demand by expanding choices in transit, biking, walking, carpooling, and flexible work schedules, and emphasizes making those choices easy to find and use. Significantly, a comprehensive TDM approach is often far more cost-effective at easing congestion than building new roadway capacity.
Why It Matters Here
Since 2004, the Grand Rapids region has maintained a no-new-roads policy, focusing limited transportation funding on maintaining existing roads rather than adding capacity. That means the region has to move more people using the infrastructure it already has, which is exactly the problem TDM is built to solve.
Right now, roughly 90% of commute trips in the region are made driving alone.
Across all trip types, about 68% are private-auto trips, and only around 14% are non-driving trips (transit, walking, or biking combined).
Even among the lowest-income households, who have the most to gain from affordable options, transit ridership sits at just 1.3%. That's a gap in access, not a lack of need.
Employers increasingly sit in locations that are hard to reach without a car, which limits who can realistically take the job.
What TDM Looks Like in the Grand Rapids Region
In West Michigan, TDM shows up in familiar, everyday forms. The Rapid's fixed bus routes connect cities and townships across the region, not just downtown Grand Rapids, which matters because the GVMC region covers a lot more ground than the city itself.
Plenty of everyday trips happen between suburbs and townships, not to and from downtown, so a regional approach has to work for all of them. Beyond the bus routes, TDM shows up as:
DASH, the free downtown shuttle that handles the last-mile connection once you're downtown.
Bike infrastructure and bike-on-bus racks that extend how far a bike commute can reach.
West Michigan Rides and other carpool and rideshare matching resources.
Employer partnerships offering flexible schedules, transit passes, or other commuting benefits.
Why Grand Rapids Needs This
GVMC, the region's metropolitan planning organization, adopted its first Regional TDM Plan to guide this work through 2029. The plan's vision is straightforward: support transportation options that move people affordably, safely, and efficiently, region-wide, while easing congestion and supporting sustainable growth.
That plan set four goals: get regional partners coordinated around a single message instead of duplicating effort, help people who live and work here get around without a car, build TDM into how the region plans for land use, parking, and infrastructure, and build lasting relationships with employers to support flexible commuting.
No single option works for every trip or every household yet, and some routes and services still have real gaps in frequency or coverage. That's why the work of TDM is never finished! Your Move GR is the communications campaign built to support GVMC's plan, helping residents, commuters, and employers across the region discover which of these options truly fit their day-to-day trips.
