A1010 and A105 Corridor Studies

At the start of 2015 ATR were commissioned to carry out an extensive multi-modal survey over two days (weekday and Saturday) which covered 25 junctions along the A1010 corridor from Ponders End to Upper Edmonton in addition to eight junctions spread along the A105.

The survey consisted of manual classified counts and queue lengths at all 33 junctions along with pedestrian surveys, saturation flow surveys, bus stop dwell time surveys, car and bus journey time surveys, ATC’s and a comprehensive OD survey for a microsimulation model. The ANPR survey element alone required 20 cameras.

With so many survey elements and sites this survey provided a logistical challenge to ensure all cameras were installed and set up prior to the survey start time. ATR overcame this through meticulous preparation, installing cameras the day before the survey where possible. Through this thorough planning, all cameras were installed, and adjusted where necessary, well before the survey start time.

In addition to the camera-based challenges there were also challenges to ensure that all enumerators (ATR had circa 30 staff on site for the weekday survey) were fully briefed on the particular survey element they had been assigned to. Staff were split into teams with each team being given a full briefing well in advance of the survey start.

With the survey taking place in early February the weather was always going to be a further challenge and despite heavy rain and hail during the survey the project was completed with no issues to report apart from a few frozen fingers and wind chilled faces!
