sDNA Pedestrian Environment Review System (PERS) study presented at CIHT event

Ringo Chan of ARUP global consulting engineers presented an sDNA pedestrian footfall model for Leadenhall Street, London at yesterday’s Chartered Institution of Highways & Transportation event, “Planning for Pedestrians”.

Ringo’s work makes use of Pedestrian Environment Review System (PERS) data both as a predictor of pedestrian destination attractiveness, and pedestrian route attractiveness. This is a hot area of research – if you are interested in using PERS with sDNA please get in touch with Crispin for more information (

The event was well attended and the work well received – thank you Ringo.
