Modelling individual vehicles through a junction or corridor to test whether a design works before it is built. The deliverable skill on transport consultancy desks — and the one where a model that runs is routinely mistaken for a model that is right.
Needed across
What you will be able to answer
A consultant's model shows a redesigned junction clearing its queues, and the authority has to decide whether to believe it. What would you look at first?
Calibration against observed data, before any of the results — modelled counts, speeds and queue lengths set against what was actually surveyed, judged by a stated acceptance criterion such as GEH rather than by whether the animation looks realistic. After that the traffic composition and the car-following and gap-acceptance parameters, because behaviour left on defaults derived from lane-disciplined traffic will overstate what a mixed-traffic approach can carry. Delay, queue length and level of service only mean something as a base-case-versus-option comparison once the base case matches the road.
