ABSTRACT
This chapter discusses the role of information contestability in evidence-based policy in planning and the transport. Information governance in planning and transport needs to change for the community as a whole to be able to handle and respond to the complex issues now arising in transport and planning. The barriers include government control of basic public geospatial data, and the necessary changes in the mode of operation of government to secure these gains. The clean room approach also permits private and commercial data to be utilized and integrated under a range of different formal agreements, constraining the manner and levels of aggregation of its deployment and so expands the common space for all parties if desired. The changes in governance and policy processes enabled by a contestable evidence-based policy framework to become possible are important, and a major potential contributor to transitions to sustainability in planning and transport.
