San Diego MTS Increases Efficiencies & Reduces Paratransit Costs through In-Person Eligibility Assessments


With a 40% increase in annual paratransit trip volume and 38% increase in spending over three years, MTS sought a solution to help responsibly control the unsustainable growth of its ADA paratransit service, Access.


A collaborative partnership with MTM Transit’s mobility management program for 100% in-person eligibility assessments, including a new process to accommodate trip-by-trip conditional eligibility determinations.


41% decrease in total certifications, 8% increase in passengers served per hour, and 15% reduction in total paratransit trips through conditional eligibility, for a cost savings of more than $550,000 over two years.



As one of the oldest transit systems in Southern California, the San Diego Metropolitan Transit System (MTS) serves an annual ridership of 88 million—including nearly 500,000 annual Americans with Disabilities Act (ADA) paratransit trips. Like many transit agencies, MTS struggled with an unsustainable growth pattern for its Access paratransit service. From 2013 to 2016, Access demand grew exponentially. Facing a 10% annual growth in paratransit ridership and a 40% rise in paratransit trip volume, MTS’s paratransit budget increased from $10.8 million to more than $15 million in just three years. With the ultimate goal of ensuring the highest level of service for its paratransit passengers and redirecting non-eligible applicants to more appropriate transportation options, MTS sought a partner for ADA eligibility certification services to help better control paratransit growth.

Historically, MTS had deployed an ADA eligibility process that was application-based and complemented by phone interviews. Following a competitive bidding process in 2016, MTS selected MTM Transit as its new eligibility certification partner. Together, using MTM’s proven mobility management model, MTM Transit and MTS transformed the eligibility process into a 100% in-person assessment model.

Access ADA paratransit services are a safety net for passengers in the San Diego area who are unable to utilize MTS’s fixed route bus and trolley services due to a limiting disability. The new in-person assessment model helps MTS ensure that only truly eligible passengers are certified to use the program. We hold all applicants to the same baseline standards for eligibility, which safeguards that eligibility decisions are fair and unbiased.

Under the model, every applicant completes a thorough, multi-step evaluation process that allows MTM Transit’s Mobility Assessment Evaluators to gather as much relevant information as possible about their conditions and limitations. The process begins with the initial application, and then flows into an in-person meeting, where the Evaluator interviews the applicant and observes how they are able to access transit services. When necessary, the Evaluator conducts a Mini Mental Status Examination (MMSE) to determine the applicant’s cognitive abilities. The Evaluator also collects supplemental information like medical professional verification, fixed route utilization history, and video footage to help inform their decision. Based on the findings, the Evaluator makes an eligibility determination. If an applicant disagrees with the decision, they have the right to an appeal. All appeals result in a more in-depth in-person functional assessment process to further examine the applicant’s physical abilities.

Value-added Services

  • Conditional Eligibility:  MTM Transit worked with MTS to establish the agency’s first trip-by-trip conditional eligibility process, with a goal to empower passengers and eliminate non-qualifying paratransit trips. During the assessment, MTM Transit’s Evaluators look at potential conditions that might prevent a passenger from using fixed route, like uneven surfaces, street crossings, extreme weather conditions, air quality, and time of travel. If one of these conditions exist, results are documented in the passenger’s file. When the passenger calls to book a paratransit trip, the Dispatcher references the file to determine if the trip meets one of the conditional requirements. If the trip does not meet a condition, the passenger must use fixed route service instead. This new eligibility component has required buy-in from MTS’s transportation vendor to ensure conditional eligibility is enforced during scheduling. All three parties—MTS, MTM Transit, and MTS’s transportation vendor—are fully vested in the process, resulting in successful enforcement.
  • Travel Training:  For applicants who are deemed ineligible or conditionally eligible, MTM Transit leverages our established travel training methods in a train-the-trainer approach. This approach teaches local social service agencies to perform travel training themselves. After completing training, agency staff are able to instruct passengers how to safety and independently use fixed route services. This helps MTS maximize travel training availability while adhering to existing staffing levels and building sustainability into the program.
  • Taxi Program Eligibility:  As part of their paratransit program, MTS assigns specific paratransit trips to taxi services. This service is reserved for single rider ambulatory trips that don’t fit the Access multi-load model, and is used when it makes the most economical sense for MTS. During the assessment process, MTM Transit’s Evaluators make an eligibility determination for taxi services to ensure appropriate use of the program.
  • Reduced Fare Application Processing:  MTM Transit’s local staff also process Reduced Fare Applications on behalf of MTS, ensuring applicants who qualify for reduced fare and passes are quickly moved through the system.
