Signalling Change

Abstract

LinSig has been the traffic signal design tool of choice in the UK for over 25 years and during this period has undergone significant development and improvement. The most recent version – LinSig3 – when released in June 2009 introduced a range of new features including lane based modelling and the ability to model larger networks of up to 15-20 junctions. Since the initial release of version 3 almost two years ago LinSig has been updated a number of times to incorporate additional ongoing research on the LinSig traffic model and optimiser which has led to large improvements in model run times, and to add new features such as SCATS™ based terminology and Google Maps integration Traffex 2011 sees the launch of the first more significant update to LinSig3 – Version 3.1. This new version includes a number of new major features as detailed in this paper as well as the usual range of smaller improvements. What’s more Lin- Sig3.1 will be available free of charge to all users with current LinSig3 support.
