AbstractPredicting how changes to the urban environment layout will afect the spatial distribution of pedestrian fows is important for environmental, social and economic sustainability. We present longitudinal evaluation of a model of the efect of urban environmental layout change in a city centre (Cardif 2007–2010), on pedestrian fows. Our model can be classed as regression based direct demand using Multiple Hybrid Spatial Design Network Analysis (MH-sDNA) assignment, which bridges the gap between direct demand models, facilitybased activity estimation and spatial network analysis (which can also be conceived as a pedestrian route assignment based direct demand model). Multiple theoretical fows are computed based on retail foor area: everywhere to shops, shop to shop, railway stations to shops and parking to shops. Route assignment, in contrast to the usual approach of shortest path only, is based on a hybrid of shortest path and least directional change (most direct) with a degree of randomization. The calibration process determines a suitable balance of theoretical fows to best match observed pedestrian fows, using generalized cross-validation to prevent overft. Validation shows that the model successfully predicts the efect of layout change on fows of up to approx. 8000 pedestrians per hour based on counts spanning a 1 km2 city centre, calibrated on 2007 data and validated to 2010 and 2011. This is the frst time, to our knowledge, that a pedestrian fow model with assignment has been evaluated for its ability to forecast the efect of urban layout changes over time.
