Turn volumes without the spreadsheet.
Turn-volume diagrams and reports for traffic engineers and transport planners.
Coming soonFrom network to report, every scenario, in one workflow
Every stage of a trip generation and distribution assessment, in the order you actually work through it.
-
01
Build your network
Lay out nodes and links to represent the intersections and roads your assessment covers.
-
02
Represent existing traffic
Add existing turning-movement volumes at each node to a layer, giving you a clean, editable baseline to build on. Use one mode or many, one time period or many.
-
03
Define activities and calculate trip generation
Set up land-use activities, input trip rates for each time period and let TurnManager calculate the trips they generate. Bring your own trip rates from any source.
-
04
Distribute traffic through the network
Generated trips are distributed across your network and added to existing volumes at every affected node. TurnManager manages primary, pass-by, and diverted trips.
-
05
Define layers and scenarios
Use one layer for existing traffic, and one or more for development traffic. Combine one or more layers into a scenario, each with an optional scale factor — an easy way to represent uniform background growth or sensitivity tests.
-
06
Generate diagrams and reports
Produce presentation-ready turn-volume diagrams and supporting reports directly from the model — no redrawing in another tool.
Built for the job between spreadsheets and full traffic models
Instead of a spreadsheet
A spreadsheet has to be built, or rebuilt, for every job — and every rebuild is another chance for a turn to be missed or a formula to break silently. TurnManager's network model checks that a network balances and that every turning movement is accounted for.
Result: accuracy you can stand behind in review.
Instead of specialist modelling software
Full traffic modelling packages are built for jobs most trip generation and distribution assessments don't need — at a cost and training investment to match. TurnManager is a specialist, purpose-built tool for exactly this assessment, without the overhead of a full modelling suite.
Result: lower cost, lower training time, faster to a result.
