Simon Crowcroft made the comments while responding to a Growth, Housing and Environment Department traffic study into the project, which raised a number of concerns about congestion and the effect on the bus service.
The document also says that the plans go against disability legislation by potentially worsening provisions for those with limited walking capacity.
‘With any scheme that is put forward to improve the lives of town residents, they [GHE] will complain about the effects of traffic flow onto the other roads and treat it as a science,’ Mr Crowcroft said.
‘It is not a science. What happens is that people make adjustments to their driving behaviour and there will only be an initial, temporary effect on traffic.
‘We keep saying that people need to adopt more sustainable modes of transport, so we cannot keep going on like this.’
The GHE study added that the loss of the eastbound bus stops would not be in line with disability legislation, which aims to improve accessibility for those with limited walking capability.
However, Mr Crowcroft said that he did not accept the department’s claim.
He said: ‘This is just an initial consultation for looking at a vision for improvement for Havre des Pas. Obviously, if there is any infrastructure issue we will look to meet those requirements.’
The Constable also rebutted a claim, contained within the GHE study, which says that the free hoppa bus service would cost £250,000 to run and would need to be funded by the parish.
‘We [the parish] never said that we would pay for the hoppa bus service. Other parishes do not have to pay for bus services and any bid for funding would include funding for that service.’
