The South of the Borough Neighbourhood Committee in Kingston upon Thames approved the installation of Speed Indicator Devices, speed cushions, and speed tables in November 2026. During these discussions, a resident questioned the accuracy of average speed data collected on Mount Road, which indicated average speeds of 22.4mph northbound and 22.3mph southbound in July 2026.
This data, collected using automatic traffic counters during school term time, also showed 85th percentile speeds of 27.7mph and 27mph.
