Public transport accessibility through co-modality: Are interconnectivity indicators good enough?

Improving the accessibility of areas using public transport modes in various combinations (or even in combination with car) is one major goal of the concept of co-modality. For co-modality, the quality of interconnectivity is a major requirement to improve accessibility and indicators exist for measuring accessibility and interconnectivity of nodes. However, in this paper we argue that co-modality is not fully measured by most common indicators. Furthermore, in that qualitative aspects are key features of co modality, indicators do not provide enough information for ex-ante analyses.
