Just look at the roads around any Ikea store, for instance.

Absolute rubbish. all large developments require transport impact
assessments. The DEVELOPER pays for these to be carrioed out and the are
examined by the councils or the prevailinbg highway authority. all
junctioons and link roads are examined for capacity and the impact that
traffic will have. The examinations are robust with factors of safety
built
into them. If the junctions start to cause a proble or reach 85% of the
capacity within the (normally) 10 years following development. the
DEVELOPER
pays for the improvement works.

I should know I write TIAs on regular basis

Does this apply where the development and the access road lie within two
different authorities?

I quote the case of IKEA Leeds, which is actually in Kirklees
(Huddersfield), and the main access point of the M62/M621 comes under Leeds
City Council.
