Highway Capacity

Capacity assessments are typically a key component of a Transport Assessment. 


Different industry standard computer software is used for junction modelling, depending on the type of junction being assessed.


As a guide the following software packages are generally used;

  • Junctions 10 PICADY Module (TRL) for major/minor priority junctions

  • Junctions 10 ARCADY Module (TRL) for mini and larger non signalised roundabouts

  • LINSIG (JCT) for signalised junctions

  • LINSIG (JCT) or TRANSYT (TRL) for linked signalised junctions and small networks


We can assist you with highway capacity assessments where they have been required as part of the transport planning process.
