We are inviting comments and background information on this our central concept behind this project, i.e., what is this thing we call transportation equity all about? We are looking for a variety of views and perspectives on our topic and not some kind of warm and glass-eyed unanimity. If we cannot handle contradictions and fuzziness, then we are not about to make headway with this one. This first note comes in from Todd Litman executive director of the Victoria Transport Policy Institute in Victoria Canada.
Evaluating transportation equity
- Todd Litman , VTPI, Canada
It is true that transportation equity can be evaluated in various ways and
that special interest groups often use equity concerns to advance their own
agenda, but it tends to be an important concern in transport policy and
planning decision-making, and there is a good body of literature on
transport equity analysis.
There are three major categories of transport equity:
1. Horizontal Equity (also called fairness) is concerned with whether
each individual or group is treated equally, assuming that their needs and
abilities are comparable. It suggests that people with comparable incomes
and needs should receive an equal share of public resources and benefits,
and bear an equal burden of public costs. It implies that costs should be
borne by users unless a subsidy is specifically justified (i.e., the “user
2. Vertical Equity. With Regard to Income considers the allocation of
costs between different income classes, assuming that public policies should
favor people who are economically disadvantaged. Policies that provide a
proportionally greater benefit to lower-income groups are called
progressive, while those that make lower-income people relatively worse off
are called regressive.
3. Vertical Equity With Regard to Mobility Need and Ability considers
whether a transportation system provides adequate service to people who have
special transportation needs (i.e., they are transportation disadvantaged).
It justifies facility design features and special mobility services that
provide access to people with disabilities. It suggests that public
subsidies should be used to provide Basic Access to transportation
Equity analysis is complicated by the fact that there are many types of
impacts to consider and people can be grouped in various ways. A particular
policy may seem equitable and justified when evaluated one way but not in
another. It is therefore important that decision-makers understand these
different perspectives and measurement units. I agree with Gabe that road
pricing is often portrayed as regressive and therefore inequitable, although
it is generally more equitable than other road funding options, particularly
if there are good alternatives to driving. This is why most experts argue
that a portion of road pricing revenues should be used to improve transport
