Why curb-to-curb service is simply not enough

It has been more than 20 years since the passage of the Americans with Disabilities Act, and many transit agencies continue to struggle with the quality of service, costs and the difficulties encountered in contracting the service. One of the most basic policy decisions an agency must make involves whether to provide door-to-door, or only curb-to-curb service.

In many American cities, ADA complementary paratransit service is still evolving. It has been more than 20 years since the passage of the Americans with Disabilities Act, and many transit agencies continue to struggle with the quality of service, costs and difficulties encountered in contracting the service.

One of the most basic policy decisions an agency must make involves whether to provide door-to-door, or only curb-to-curb service. The more I work in the field, and the more I get to know real people with disabilities, the more I believe that door-to-door service is the way to go. Why? Because in many cases, curb-to-curb is simply not enough.

In retrospect, I think it is fair to say that most transit agencies were dragged kicking and screaming into the provision of demand-responsive paratransit. A majority of agencies chose the option of providing curb-to-curb service. What many of them lacked, however, was an understanding that the key phrase in the ADA regulations was not curb-to-curb or door-to-door, it was origin to destination:    

•    The basic mode of service for complementary paratransit is demand-responsive, origin to destination service... The local planning process should decide whether, or in what circumstances, this service is to be provided as door-to-door or curb-to-curb service.
— 49 CFR, Part 37.129.

In a recent survey of the websites of 34 agencies, 14 say that they provide door-to-door ADA service, 16 are clearly curb-to-curb and four are unclear. Of the 16 agencies that identified themselves as “curb-to-curb,” only six specifically mention that they will provide additional (i.e. door-to-door) service upon request. Interestingly, two of the largest agencies in the country prohibit going beyond the curb.  

There have been a number of clarifications issued by the Federal Transit Administration on the subject of origin to destination service, since at least as early as 2005. Here is one of the most definitive:

•    The U.S. Department of Transportation issued an item of “Disability Law Guidance” entitled Origin-to-Destination Service, dated Sept. 1, 2005. The purpose of the guidance, as stated in the introduction, is to answer the question: “What are the obligations of transit providers to ensure that eligible passengers receive ‘origin-to-destination’ service?”
The document discusses the subject at length and concludes:

•    Under the ADA rule, it is not appropriate for a paratransit provider to establish an inflexible policy that refuses to provide service to eligible passengers beyond the curb in all circumstances. On an individual, case-by-case basis, paratransit providers are obliged to provide an enhancement to service when it is needed and appropriate to meet the origin-to-destination service requirement. We recognize that making individual, case-by-judgments may require additional effort, but this effort is necessary to ensure that the origin-to-destination requirement is met.  

The above also comes with a corresponding requirement that reasonable efforts be made to inform the riding public that such additional service is available.

Given the requirements for “origin-to-destination” service, the choices are to have door-to-door service all the time or some of the time. If the choice is “some of the time,” then the policy is “curb-to-curb, and if you want help from there you have to ask for it.” In addition, such a policy must be communicated to customers, and it must be understood by staff and drivers, as well as customers. It seems complicated and fraught with potential problems.  

If you have to provide door-to-door service some of the time, why not just do it all the time? Wouldn’t that be a far better policy decision?
