Dynamic Route Guidance Systems (DRGS) permit drivers to make informed route choices during their journey. The impacts of their choices affect not only themselves but also other travellers and the network as a whole. This paper assesses the impact of DRGS on a medium size network in Tyne and Wear, UK under recurring and non-recurring congestion scenarios during a typical peak hour using micro-simulation software VISSIM (by PTV). Different penetration levels of vehicles equipped with DRGS are hypothesised and tested for each scenario. The analysis indicates time savings and queue reduction are maximised at 40% and 60% of cars equipped with DRGS in the recurring and non-recurring congestion scenarios respectively. The findings also indicate a marginally greater benefit to the unequipped vehicles due to the presence of equipped vehicles for the network modelled.
