What is demand response transportation?
Demand response transportation is service where a rider or someone acting for them books a trip and a vehicle is dispatched to carry them between their own pickup point and destination, with no fixed route or schedule. The FTA tracks it as its own transit mode, DR. Most NEMT runs this way, and Texas Medicaid enrolls NEMT companies as Demand Response Transportation Service providers.

The federal definition
The FTA’s National Transit Database treats demand response (DR) as its own transit mode. Its glossary describes cars, vans, or small buses that run in response to calls from riders or their agents, with the operator dispatching a vehicle to pick them up and take them where they are going. Two features set it apart:
- No fixed route or schedule. Vehicles follow a route or timetable only temporarily, for a special need.
- Shared, flexible trips. A vehicle may collect several riders at different pickups before dropping them off, and may be interrupted on the way to pick up someone else.
The ADA regulations define it by what it is not. Under 49 CFR 37.3, a demand responsive system is any system of carrying people that is not a fixed route system, and a fixed route system runs a vehicle along a set route on a set schedule. The NTD groups DR with demand response taxi, vanpool, jitney, and publico as “non-scheduled” services.
Demand response vs fixed route
| Fixed route | Deviated fixed route | Demand response | |
|---|---|---|---|
| Path | Same route every trip | Set path, leaves it on request | Built around each booking |
| Timing | Published schedule | Generally set times | Set by the booking |
| Where riders board | Stops | Stops, or a requested point off the route | Usually their own address |
| Examples | City buses, rail | Routes that detour on request | NEMT, ADA paratransit, dial-a-ride, microtransit |
The trade-off is cost. A 2025 Transit Cooperative Research Program synthesis finds demand response costs more per passenger trip than fixed route, because trips are longer, demand is thinner, and vehicles carry fewer riders per hour. Most of it also runs curb to curb, which the synthesis names as another reason it is less efficient.
Where NEMT fits
Medicaid transportation mostly runs as demand response: a broker or plan authorizes the ride, and a van or sedan goes to the member’s door. It sits beside fixed route rather than replacing it, because programs pick the least costly mode that works for the member. Virginia’s fee-for-service program gives bus tickets when home and destination are within a quarter mile of a stop and the member can walk there safely. Missouri bars bus assignments when the walk to the stop is more than four blocks or half a mile, or when the member has conditions such as a high-risk pregnancy.
Public transit agencies run demand response too. CMS’s coverage guide (SMD 23-006) says public transit is often among the least costly options, and when a governmental broker uses a public provider, Medicaid should pay no more for ADA paratransit or demand response than other state human services agencies pay for comparable rides. The paratransit and microtransit entries cover the transit side.
Texas uses the term as a provider type. Its fee-for-service Medical Transportation Program lists demand response transportation (taxis, wheelchair vans, and other carriers under contract) alongside mass transit passes and mileage reimbursement, and TMHP enrolls Demand Response Transportation Service providers, who bill T2003 for each authorized one-way leg. The Texas guide covers how to join.

Frequently asked questions
- Does all NEMT count as demand response transportation?
- Not exactly. NEMT is a Medicaid benefit, and demand response is a way of running service. Most NEMT trips run as demand response, booked ahead with a vehicle sent to the rider's address. Medicaid can also pay for fixed route bus tickets when they work for the rider. Virginia's fee-for-service program offers them when home and destination are both within a quarter mile of a bus stop.
- What is a DRTS provider in Texas?
- A Demand Response Transportation Service provider is a company enrolled with TMHP to carry fee-for-service Medicaid, CSHCN, and TICP riders for the Medical Transportation Program. DRTS providers bill T2003 for each authorized one-way leg, with a modifier for the county type. From September 1, 2026 the rates are $33.83 metro (U1), $79.63 rural (U2), and $62.31 micro or suburban (U3). Managed care trips follow each plan's own rules.
- What is deviated fixed route service?
- The FTA's National Transit Database defines it as service that follows a set path at generally set times but will leave the route to pick up or drop off riders who ask for it. It sits between fixed route and full demand response.
- Is ADA paratransit a type of demand response?
- Yes. The National Transit Database describes ADA complementary paratransit as origin-to-destination demand response service, or on-call demand response to an accessible fixed route. Riders must qualify under the ADA because a disability keeps them from using the fixed route system.
