This book describes the procedure to create a road network in a GUI environment of a computer. With the network, the transport performance, including delay and travel time can be evaluated. In addition, optimisation of traffic signal can be achieved with genetic algorithm (GA). The optimal signal plan and its corresponding traffic states (flow and number of vehicles) can be derived. Possible extension with the plugin for more complex dynamics, e.g., heterogeneous flow, is reserved.

Sigmix is a software tool that can

Simulates the macroscopic traffic flow (engined with Cell Transmission Model (CTM)
Optimises the traffic signal with [total travel time] or [delay] minimised.

It can be applied in urban junction/arterial/network.

It is…

Easy to operate Graphical User Interface (GUI)… As easy as you can imagine
Aided with movement compatibility tool. Provides with
- Compatibility checking,
- intergreen setting,
- stage setting suggestion.
armed with universal model that can deal with both congested and uncongested scenario.
equipped with objective function according to user needs…to minimise ‘Total Travel Time’ or to minimise’Delay’
Equipped with dialogue to see the [number of vehicles] or [outflow] by time
capable of finding optimised signal plan

It’s main physical simulator is: Cell Transmission Model (CTM) that keeps the traffic moving. It’s optimisation technique is Genetic Algorithms (GA) that mimics the mother nature of evolution to find the best traffic signal you need!

The charge-free edition ($ 0.00) is the ‘Citizen’ edition that provides partial functions:
