CCTV cameras are being put up in St Peter Port as part of a traffic survey.
Automated vehicle counters will be positioned at the busiest junctions.
The cameras will be in place from Wednesday (7 July) for seven days, recording how much traffic there is on the main roads into St Peter Port.
The States says they will build a picture of traffic flows and the data will be used for a 'number of current projects'.
Spots being monitored include Weighbridge Roundabout; the junction between Fountain Street and The Quay; the top of Le Val des Terres; Trinity Square; and various points on St Julian’s Avenue and The Grange.
They will also survey junctions on some smaller but busy routes, such as Cornet Street and Tower Hill.
The cameras will be in place for up to a day at a time in those locations.
The study is being conducted by a UK firm, using specialist equipment and analysis systems.
The recordings will be automatically analysed, using a specialist computer system.
States of Guernsey says the data will help with the planning of regeneration of St Peter Port's Lower Pollet, South Esplanade and Mignot Plateau, and Mansell Street/Le Bordage and be used by the Seafront Enhancement Area programme.
“A traffic assessment is a key element when considering any development options. Any potential impacts, positive or negative, are assessed against the current traffic levels, so having up to date information on that is essential. .
“The study was due to happen last year, but ultimately was delayed due to Covid-19. The travel restrictions and self-isolation requirements prevented the specialist contractors from coming to set up equipment, but there was also little point carrying on with a study of traffic levels in Town when schools were closed, most islanders were working from home, and bars, restaurants, and non-essential shops were all shut. However that delay turned out to be an opportunity.
“A number of other projects have progressed in the meantime, which will also need up to date information on traffic flows and vehicle numbers. This is the result of States Committees working together, so we can satisfy all of these requirements in one study.” - Damon Hackley, Director of Operations – Economy, Infrastructure, Environment, Culture.
