TfL Ref: FOI-0114-2122 Thank you for your request of 14th April 2021 asking for SCOOT data for various sites in south east London. Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. Specifically you asked: “We would like to use a FOI to request SCOOT (Split Cycle Offset Optimisation Technique) Data for the following sites since Jan 1 2019 please. 1. 08/070 Denmark Hill /Champion Park going North/South and East/West 2. 08/102 DOG KENNEL HILL / GROVE LANE / CHAMPION HILL North/South - and East and West separately 3. 08/133 DOG KENNEL HILL / PYTCHLEY ROAD / SAINSBURYS. 2ND OTU 08/633 North/South 4. 08/334 EAST DULWICH GROVE / TOWNLEY ROAD / GREEN DALE East/West, North/South 5. 08/011 DULWICH VILLAGE WAY / EAST DULWICH GROVE / RED POST HILL. East/West and North/South 6. 08/023 DULWICH VILLAGE / TURNEY ROAD / CALTON AVENUE. North/South 7. 08/010 LORDSHIP LANE / BARRY ROAD / WOODWARDE ROAD. North/South and East/West 8. 08/020 LORDSHIP LANE / DULWICH COMMON. North/South and East/West 9. 08/342 A205 DULWICH COMMON BY FRANK DIXON WAY. East/West 10. 08/017 DULWICH COMMON / COLLEGE ROAD East/West 11. 08/214 THURLOW PARK ROAD BY WEST DULWICH STATION. North/South and East/West 12. 08/273 A2214 NUNHEAD LANE / PECKHAM RYE (EAST). East/West We would like to get ‘Flow’ & ‘Congestion’ data for each location in graph format if possible please. The requested information is attached. Please note the following explanation of what each column refers to within the spreadsheet: • SCOOTNodeID – Refers to the SCOOT Junction ID • NodeDescription – A brief description of the location of the Junction typically by road name • Latitude – The position of the junction along the North/South plane • Longitude – The position of the junction along the East/West plane • NumberOfLinks – Refers to the number of SCOOT links which approach the Junction • Date – The date of the data • TwentyFourHourVehicleFlowTotal – The total flow observed within a 24 hour period across all links approaching the junction • FlowDataCompletenessPercentage – Refers to the availability of data; 100% is a complete dataset. • AverageCongestionPercentage – The average congestion within a 24 hour period across all links approaching the junction • CongestionDataCompletenessPercentage – Refers to the availability of data; 100% is a complete dataset Note further that SCOOT Flows may differ with other validated counts as the SCOOT system utilises loop occupancy as it primary source of data. This is then modelled into a flow count via an average occupancy per vehicle. This is often sensitive to over or under saturation, e.g. when vehicles are sat over the detector for long period of time such as in congestion queuing at the lights. The detectors are often sited at a distance from the junction where this is minimised, but sometimes - especially when junctions are close together - this issue is exaggerated. Therefore SCOOT Flow should be used more to generalise trend of demands and not actual counts. SCOOT Congestion data is recorded based upon the percentage of time the detector is registering activity without breaks (suggesting a vehicle is stationary upon it.). The data provided here is given as recorded and we are not able to validate it. If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me. If you are considering submitting a further FOI request please think carefully about whether the request is essential at this current time, as answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. Where requests are made, please note that our response time may be impacted by the current situation. Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed. Yours sincerely, David Wells FOI Case Officer FOI Case Management Team General Counsel Transport for London
