ABSTRACT
This chapter builds on the previous chapter by presenting the findings from a larger-scale on-road investigation of driver, motorcyclist and cyclist Situation Awareness (SA) in different road environments. The study aimed to identify key differences in SA between drivers, motorcyclists and cyclists, to pinpoint the causes of these differences and to identify potential incompatibilities that arise when road users engaged in the same road situations experience them differently. The analysis confirms Chapter 3’s findings that SA is different across road users, with the findings indicating that SA is heavily influenced by schemata, transport mode and the nature of the road environment. In addition, the findings demonstrate that some of the differences in SA between road users may be problematic. Opportunities for enhancing the compatibility of road users are discussed, including manipulation of schemata through experience, training and education, and the use of targeted road design interventions. In particular, the critical role of road design in supporting SA across different road users and in ‘connecting’ road users is emphasised.
