There might be a correlation between Locus of Control (LOC) and trust. I guess the LOC could be used to measure the tendency of personal belief (towards internal or external) at various stages of evaluation of interventions like Focus Group Discussion, consultation or workshops. Focus group discussion and stakeholder consultation could be done to evaluate the feedback of road users and to build the trust and positive inter-relationship among driver and pedestrian. Huxham and en Vangen (2005) describe a trust-building loop where trust is built incrementally by managing risk and achieving small wins; however, it typically takes 2.5 years for relationships to become sufficiently good. Zucker (1986) has highlighted the importance of communication in establishing a shared base of knowledge, critical to the promotion of trust. Prior consultation and focus group discussion among the stakeholders should help to identify risks (based on a self-reported view of driver and pedestrian) with a range of opinions on risk mitigations. A questionnaire needs to be developed to ascertain how far mutual trust builds on FGD/consultation, and how it changes the attitudes of the drivers and pedestrians to the proposed intervention. Here, Locus of Control could be an appropriate personality trait concept to formulate trust questionnaire.
