CONTRAM > Dynamic Modelling
CONTRAM provides the advanced dynamic traffic modelling features that are needed for
applications such as:
- Highly congested networks with time varying traffic flows
- Priority lanes for buses, high occupancy vehicles or HGVs
- Road user charging schemes
- Modelling incidents
- Driver information systems
CONTRAM divides the day into time slices which are used to model the build up and
decay of traffic. Vehicles are assigned to their minimum cost routes, taking account
of traffic interactions and delays caused by other vehicles on the network. A journey
can cover several time slices during which traffic demand and network conditions can
vary and over-saturated conditions may occur temporarily, as in real life.
Key modelling features include:
- An unlimited number of time slices
- Up to 32 user definable vehicle classes
- Advanced junction modelling
- Link-based speed-flow relationships and tolls
- Left or right hand drive
- Dynamic matrix estimation
CONTRAM's dynamic ability means it can model unexpected events such as
incidents that reduce network capacity and the effects of driver information systems.
It can also handle more specific requirements such as modelling special vehicle lanes.
for buses or HGVs and banning turning movements in certain situations.
