Question

To ask the Senior Deputy Speaker, further to his Written Answer on 19 September 2023 (HL9892), when he was informed that there was more up to date information than he provided in that Answer, as set out in his Written Answer on 5 March 2024 (HL2638).

I was recently made aware that the answer to HL9892 on 19 September 2023 used data collected from a study in 2019 which looked at the total number of vehicles accessing and leaving the Estate from both Carriage Gates and Black Rod's Garden. This data was used as it was from a study carried out by traffic consultants prior to the COVID pandemic and helped inform the implementation of the one-way system in January 2023. The study provided an average estimate of traffic movements on the Estate of circa 3,500 vehicle movements in sitting times, compared to 2,500 vehicle movements during recess periods.

Since the implementation of the one-way system in January 2023 counting has been carried out internally, and the system was refined to provide more precise figures, rather than an estimate. This data was used to answer the written question HL2638 on 5 March 2024, to give an average of 4,052 vehicles in sitting times and 2,285 in recess, based on the data collected in the 2023 calendar year. Unfortunately, it was not identified in HL2638 that this was based on 2023 figures rather than the original 2019 data.
