1. Identify the problem : The first step is to clearly define the problem or issue that needs to be
addressed. Examples include: areas of congestion.
2. Collect data: The next step is to collect the data needed to create a computer model. Because
the outcome of a model depends on how realistic it is, data needs to be collected by watching
for long period of time. Data could include traffic volume, travel time data, accident data, road
conditions, climate and other relevant information.
3. Choose modelling approach: The next step is to choose the appropriate modelling approach
based on the problem at hand. Examples include: integrated simulation models, macroscopic
simulation models, etc.
4. Develop the model
5. Validate the model: Once the model has been developed, it must be validated to ensure that it
accurately reflects the real- world traffic system.
6. Use the model to analyze the problem: This involves simulating different scenarios and
conditions to identify the optimal solutions.
7. Implement the solutions
