Article review: “Genetics of traffic assignment models for strategic transport planning”
The article under review is about traffic assignment models which are used to forecast traffic flows and travel times for strategic (long-term) transport planning and project appraisal [1]. To review and classify traffic assignment models, the authors analogize them to genetics. The article says every traffic assignment model has the same DNA (theoretical framework) for strategic transport planning, but different genes (capability). There are three genes: spatial capability, temporal capability and behavioural capability, which are defined to describe models. Each capability contains three or four assumptions which the authors liken to nucleotides. In addition, each assumption has different features, and the authors use the first letter of each feature to code the feature [1]. For example, one assumption for spatial capability is shape of the fundamental diagram which could be linear,…
