Road closures in Seven Sisters/West Green Road
Cadent Gas has begun a major project to improve the reliability of its network. There will be road closures until September 2024. See all details about the major roadworks project.
We're committed to carrying out comprehensive monitoring of schemes introduced under our ambitious Streets for People initiative.
Monitoring of Streets for People schemes is needed to:
Things we will monitor across the Streets for People initiative include:
The following documents set out the monitoring approach for specific Streets for People schemes:
Monitoring data will be published on My Haringey when it is available. To access the data, click on the 'My Maps' tab and click the 'Streets for People - Monitoring' map category.
The council commissioned a wide range of monitoring data prior to the implementation of the LTNs. The pre-implementation data has already been uploaded onto the maps on My Haringey.
We use different tools to monitor the Streets for People schemes.
Automatic traffic counters measure traffic flow (volume) and speed. They use pneumatic tubes installed across the width of a road and classify vehicles into various groups, such as cars, buses and heavy commercial vehicles. Automatic traffic counters are typically installed for one week.
Manual classified counts are carried out using either enumerators or video cameras. They are normally used to collect junction turning counts by vehicle class and can provide volume, class, and origin and destination data for a specific time (for example, 12 hours or peak periods).
VivaCity Labs Ltd uses camera artificial intelligence sensors to accurately measure up-to-the-minute urban traffic movements. Their cameras record classified count data (9 modes of transport), vehicle paths, median journey time and speed.
We've signed a contract with VivaCity Labs Ltd for 27 sensors across Haringey, which will be collecting data 24 hours a day for a minimum of 5 years.
Diffusion tubes are widely used for indicative monitoring of ambient nitrogen dioxide (NO2). They take a sample over a period of time (typically 1 month), which allows assessment against the annual objective of 40 µg/m3. Their accuracy is limited, therefore the results must be adjusted based upon local or national co-location studies with chemiluminescent analysers.
The technology provided by eLichens allows the council to collect live air quality information minute by minute. This includes concentration of CO2, PM1.0, PM2.5, PM10, temperature, ambient light, pressure, humidity, NO2 and Ozone O3.
The air quality data and VivaCity cameras output will be updated quarterly.
