SDG #11 is to “Make cities and human settlements inclusive, safe, resilient and sustainable”
Within SDG #11 are 10 targets, of which we here focus on Target 11.2:
By 2030, provide access to safe, affordable, accessible and sustainable transport systems for all, improving road safety, notably by expanding public transport, with special attention to the needs of those in vulnerable situations, women, children, persons with disabilities and older persons
Target 11.2 has one indicator:
Indicator 11.2.1: Proportion of population that has convenient access to public transport, by sex, age and persons with disabilities
For public transport to be convenient, it must perform in adherence to the timetable and the routes must be able to meet capacity. For it to cater to those with special needs, paratransit services may need to be in effect to supplement the public routes.
The countries of the European single market take the lead for this indicator, alongside Israel and New Zealand. The populations of these and a handful of smaller states each had greater than 90% convenient access to public transport as of 2020.
Countries with less than 10% access were Zambia, Iraq, Jordan, and the Solomon Islands.
