Planning Engine

Common Terms Program : One complete instance of WISE consisting of the Strategies, Planning Characteristics, Project information, Planning analysis and Operation Analysis. Program : One complete instance of WISE consisting of the Strategies, Planning Characteristics, Project information, Planning analysis and Operation Analysis. WorkSpace : The folder which contains all of the material for ONE Program(from above). This is an active directory for all activity within the current Program. WorkSpace : The folder which contains all of the material for ONE Program(from above). This is an active directory for all activity within the current Program. Project : One instance of construction with a Program. Each Program must have between 2 and 5 Projects. Project : One instance of construction with a Program. Each Program must have between 2 and 5 Projects. NeXTA: Network Explorer for Traffic Analysis which is used to import Networks to WISE. NeXTA: Network Explorer for Traffic Analysis which is used to import Networks to WISE. Network : The NeXTA generated network which contains the model where the WISE Program exists. Network : The NeXTA generated network which contains the model where the WISE Program exists. Planning Mode : Mode which allows user to generate a Program and run WISE Analysis Engine Planning Mode : Mode which allows user to generate a Program and run WISE Analysis Engine Operation Mode : Mode which allows users to interface with DynusT to run Base Scenario and individual Project Scenarios to determine Work Zone Volumes with and without Projects. Diversion Results are fed back to Planning Mode. Operation Mode : Mode which allows users to interface with DynusT to run Base Scenario and individual Project Scenarios to determine Work Zone Volumes with and without Projects. Diversion Results are fed back to Planning Mode.

Planning / Operations Interaction Operation Mode is Built From Planning Information Operation Mode is Built From Planning Information Operation uses the same Network, Planning Characteristics and Projects as the Planning Mode. Operation uses the same Network, Planning Characteristics and Projects as the Planning Mode. Operation Mode intent is to provide an “Operation Diversion” for each project within the Planning Mode to be applied to the WISE Analysis Engine. Operation Mode intent is to provide an “Operation Diversion” for each project within the Planning Mode to be applied to the WISE Analysis Engine. Operation Diversion is calculated in the Operation Mode: Operation Diversion is calculated in the Operation Mode: Operational Diversion is made available to the user in the Project Information Section once the Base and Project Scenarios have been run for a given Project. This can be accessed by the following: Operational Diversion is made available to the user in the Project Information Section once the Base and Project Scenarios have been run for a given Project. This can be accessed by the following: Select Planning Tab -> Project Info Tab -> “Go To Project” for the Project desired. “Operation Supplied” will display the amount Select Planning Tab -> Project Info Tab -> “Go To Project” for the Project desired. “Operation Supplied” will display the amount
