The JRF have produced a new report on the benefits of providing new public transport in deprived areas.
One of the conclusions the authors draw from their research is:
Improving public transport information and helping with the cost of fares was as important as improved bus services in helping people on low incomes move from welfare into work.
Looks like the recommendation to local policy makers will fall on the stony ground, at least as far as Mayor Johnson is concerned:
Provide help with the cost of transport to make travel more affordable for people on low incomes, e.g. the newly introduced Transport for London scheme for people on income support (and/or set low standard fares generally).
