‘Bias’ hinders active travel schemes

SUPPORT for schemes that promote cycling and walking is hindered by ‘psychological bias’, a new report has found.

The impact of active travel schemes is often more positive than people expect, according to the Economic and Social Research Institute (ESRI). The knockon effects on local shops and food outlets are positive, and traffic congestion is eased. They also encourage the public to walk or cycle, with cycleways and paths segregated from motor traffic on a route.

The study by the ESRI’s Behavioural Research Unit reviewed international evidence on the effects of infrastructure changes designed to promote cycling and walking, including the impact on communities and public opinion. The research, commissioned by the National Transport Authority (NTA) and Fingal County Council, found strong evidence that improving active travel facilities boosts rates of cycling and walking.

But despite improved safety, reduced emissions, better air quality and improved public health, proposals to alter existing infrastructure to aid active travel often face opposition from communities – based on negative expectations about the effects on businesses and traffic.

The ESRI review illustrates psychological biases that may hinder support, including status quo bias; primacy effects, where people give credence to the first piece of information they hear; and collective illusion – e.g. the belief among supporters of schemes that they are in a minority. The review noted that dedicated infrastructure that allows cyclists to complete a full journey while feeling safe increases cycling in all age groups.

Dr Shane Timmons, from the ESRI, said: ‘Opposition to traffic policy changes is not unique to Ireland. However, in multiple countries, research finds that people become more positive about changes once they are implemented. Open and fair consultations with communities to address concerns about traffic, local businesses and safety are helpful.’
