The mitigation measures for Weycock roundabout are untested and the impact of a single entrance for the KS1 site, close to the congested Port Road, remains totally unresearched. Critical questions about traffic data collection—its timing, method, and representativeness—are unanswered. Persimmon’s reliance on data from a single day in September 2023 raises significant questions about its validity or real utility. The same point holds for BP14 and BP14A. Despite extensive technical looking data, the timing and methods of data collection remain opaque, raising concerns about the seriousness, accuracy and reliability of the traffic assessments.
HG1 KS1: Mitigation measures for Weycock roundabout – marginal widening and signalization - remain untested conjecture. Further, the sentence (BP14, 4.2.13): ‘controlled crossings and access arrangements for Land at North West Barry’, have been ‘excluded.’ and 'The access for Land at North West Barry and the impact on Waycock Cross Roundabout is to be considered ... between the land promoter and the Vale of Glamorgan Council' raise a core question. The core question is: what will be the effect of "one" entrance/exit for the KS1 site, that is 20 yards from the Weycock roundabout, with up to 700 plus potential cars traveling to and from work, schools, shops, etc edging directly onto a massively congested Port Road every weekday? A crucial dimension of the traffic dilemma is simply absent here in studies. In addition the question: "HOW" and "WHEN" was the traffic data collected? Neither BP14 or BP 14A provide ANY information here. Persimmon indicate in their document that "one" day in September 2023 provided the data. Can this really be taken seriously as anything more than an unrepresentative three year old snapshot? How did they collate data, what time of day did they collect it etc. All unanswered questions. However Persimmon build up 500+ pages of data on this thin example. I suspect the same holds for the data in BP14 and BP14A. It is an impressive fiction. Photos provide indication of normal traffic on Port Road and Pontypridd Road on the roundabout and immediately by the proposed entrance to the KS1 site as of March 2026
