The need to provide efficient public transport services in urban areas has led to the implementation of bus priority measures in many congested cities. Much interest has recently centred on priority at signal controlled junctions, including the concept of pre-signals, where traffic signals are installed at or near the end of a with-flow bus lane to provide buses with priority access to the downstream junction. Although a number of pre-signals have now been installed in the UK, particularly in London, there has been very little published research into the analysis of benefits and disbenefits to both buses and non-priority vehicles at pre-signalised intersections. This paper addresses these points through the development of analytical procedures which allow pre-implementation evaluation of specific categories of pre-signals.

Early career researchers are of increasing interest, regardless of national boundaries, given both policies to enhance international competitiveness, and concerns about individuals turning away from academic careers. As a result, there is a growing literature documenting how early career researchers navigate their journeys and decide to stay or leave. Our research is situated within this literature, yet is distinct in using a longitudinal qualitative team-based approach that has led to the conception of identity incorporating both the continuity of stable personhood over time and a sense of ongoing change. The scholarly contribution of this work is to articulate a contrasting perspective to the structural or systemic one common in examining early career researcher experience. Our goal in this chapter is to make transparent the decisions and actions underlying our approach and, in so doing, demonstrate the potential of researching the construction of identity in this way.
