Built for transportation engineers

Build better VISSIM models in less time.

VHelper automates repetitive work, catches coding errors early, and turns simulation results into report-ready visualizations.

Version 6 uses traffic-count targets and StreetLight OD data to estimate OD Matrix - then builds Vehicle Inputs, Traffic Compositions, and complete end-to-end Static Routings with one click.

A complete demand-building workflow

Spend more time engineering—and less time on legwork.

Go from observed counts to runnable model demand.

Bring traffic evidence in

Use traffic-count targets together with StreetLight OD data across freeway, managed-lane, collector-distributor, and arterial demand.

Estimate corridor demand

Run vehicle-class-aware OD Matrix Estimation while respecting which paths each vehicle type can actually use.

Build the runnable model

Automatically create Vehicle Inputs, Traffic Compositions, and complete end-to-end Static Routings ready for VISSIM.

Model demand across the corridor—not in isolated pieces.

VHelper 6 discovers how zones, ramps, managed lanes, transfers, and feasible paths fit together across the freeway-and-arterial system.

  • Automatically associate zones and ramp movements
  • Respect GP, Express/HOT, collector-distributor, and arterial paths
  • Visualize OD flows and routing paths before export
  • Trace demand contributions and diagnose infeasible movements

Trusted in real project work

Built around the details engineers notice.

Transportation professionals use VHelper to reduce tedious review effort and uncover model issues that are easy to miss.

I only wish I’d known about VHelper years ago.
