Kate try the following (just a few ideas in haste) 1) data collection via online methods(including vector gis data as well as GPS capture choice models and GIS surveys) 2) data provision via online methods (including mapping and data cube analysis) 3) formal metadata intermediation for data discovery and integrated access and agreagtion 4) ADUs/ITS real time data assembly and reduction to supplement survey data 5) online modelling (including open source) 6) integration of safety data with travel and other transport 7) mass data capture and reduction from sensors (including weather ...and its and...) 8) data observatories 9) governance aspects of urban data, collection access contestability and use 19) Intellectual property issues/business models/ added value models for data aggregation 11) privacy and ethical issues 12) integration of different modal views in data segmentation and recycling(bicyes are trendy, but walking, marginal mobility modes, mopeds, scooters, electric 2 and 4 wheeled vehicles all ft into different performance and use segments- and data collection use and feedback and monitoring is a bit haphazard still) 13) roles of data in policy and consultation contestability processes (a subset of governance) 14) data gaps fro issues of short and long term policy support 15) performance indicators for urban data form the standoint of very different stakeholders Ive worked on most of these crossovers at at least some level(however small) and can confirm that they all offer excellent cross cutting capacity for interesting sessions..many between Data, User, safety and even road management and library areas of committee interests in TRB will that do as a start? cheers marcus -- ============================================================================== Dr Marcus Wigan, Personal website http://go.to/mwigan Personal email m.wigan(a)hertford.oxon.org * Principal Oxford Systematics, Box 126 Heidelberg 3084 Australia * Senior Consultant Demis BV, delft, The Netherlands * University of Melbourne - Honorary Professorial Fellow, Civil and Environmental Engineering, - Partner, GAMUT, Faculty of Architecture and Planning, University of Melbourne * Emeritus Professor of Computing and of Transport Systems, Edinburgh Napier University Scotland * Visiting Professor, CTS, Civil and Environmental Engineering, Imperial College London ==============================================================================
