Hello. I am writing to request traffic and air quality data that TFL holds on Brownlow Road, N11 from the past 5 years. Specifically, I require: - Results of any traffic counts that have been done on Brownlow Road, both peak and off-peak - Results of any traffic count investigations that were done while Warwick Road was closed (e.g. due to road repairs) - Any air quality monitoring data that the TFL has on Brownlow Road (NO2/NOx, PM10, PM2.5, SO2, CO and any other data that is collected). If you have raw data and adjusted figures, please provide both, along with information on how and why the figures were adjusted. Has TFL carried out any investigations over the past 5 years that in any way relate to traffic flow and/or air quality on Brownlow Road, including any independent studies that were commissioned by TFL? These may include but are not limited to investigations relating to traffic on Warwick Road or the right-hand turn from Bounds Green Road onto the A406. If yes, please send me the findings from these investigations. Please provide data in xls format and any reports as a pdf. If you can identify any ways that my request could be refined, I would be grateful for any further advice and assistance. Please get in touch via email Many thanks for your time, and I look forward to your response. Best,
