Technical basis

Calculated to the standards and regulations in force.

TrafficNex builds on the documents below. The engineer still checks the results and remains responsible for them.

How it works

Workflow of the two core features.

5 standardized steps from survey data to technical report.

Two core features, choose from the home screen.

The home screen has two feature cards. Pick the one that matches the job at hand; they work independently, so you do not need to finish one before the other.

  • Traffic survey report — use it when you already have raw survey counts. Enter vehicle counts per vehicle type in 15-minute slots, across several days and both directions; the app totals the flow, converts to passenger car units, forecasts future years and exports a Word (.docx) report.
  • Traffic flow modeling — use it to determine lane counts. Choose a road segment, T-junction or 4-way junction, enter the flow for each turning movement and adjust parameters per TCVN 13592:2022 to compute lanes; then draw the junction layout and export the results table to Excel.

Why TrafficNex

Specialized solution for traffic analysis & design.

Standardizing data collection, intersection modeling, and technical indicator assessment per QCVN and TCVN.

Up to 80% less processing time

Cuts the reporting workflow from 3–5 days to just 0.5–1 day. Enter data once, and the system processes it automatically and outputs results instantly.

≥ 80% time saved

Standardized & Accurate Data

Completely eliminates errors from manual Excel formulas and scattered file handoffs. Computation data is centralized, consistent, and easy to trace and verify.

Per QCVN, TCVN, TCCS

Diagram & Traffic Flow Visualization

Automatically generates junction diagrams, vehicle trajectories, and lane count summary tables as soon as you enter data — no more manual diagram drawing.

Road · T-junction · 4-way

Compliant with Technical Standards (QCVN/TCVN/TCCS/TT…)

Integrates traffic volume aggregation, data analysis, and technical indicator calculation under the system of Regulations, Standards, and Base Standards (QCVN/TCVN/TCCS). Design coefficients and level of service (LOS) can be flexibly customized for each project.

Flexible design parameters

Connected data ecosystem

Fully integrates 5 specialized modules (Nex Count, Nex Model, Nex Intersection & Signal, Nex LOS, Nex Simulation) on a single shared data platform, with no time wasted re-entering data between stages.

5 specialized modules

Optimized tooling

TrafficNex automates repetitive calculation steps, acting as a capable technology assistant that lets experts stay fully in control of verification, quality control, and the final decision.

Ecosystem

Data flows seamlessly from vehicle counting to service quality assessment

A continuous data flow from traffic surveys to level of service (LOS) assessment — completely eliminating data re-entry between stages.

  • Live01 · NEX COUNT

    Nex Count

    • Standardizes, classifies and aggregates vehicle traffic survey data by time slot (PCU/h).
    • Automatically generates traffic volume appendices.
    Count & classify
  • Live02 · NEX MODEL

    Nex Model

    • Models and analyzes traffic flow on road segments and junctions.
    • Automatically sizes the design lane count and forecasts future-year traffic volumes per the current regulations and standards (QCVN / TCVN / TCCS / ...).
    • Exports visual traffic flow diagrams.
    • Automatically exports technical reports with vehicle-mix and traffic-variation charts.

  • Coming soon03 · NEX INTERSECTION & SIGNAL

    Nex Intersection & Signal

    • Determines the junction's scale and models the geometry (turning lanes, deceleration/acceleration lanes, tapers, cross-sections) of complex junctions.
    • Exports the junction geometry diagram after the calculation.
    • Automatically computes and optimizes signal cycles (phase plan, green, yellow and red intervals) based on actual traffic flow and current standards.
    • Automatically generates signal phase diagrams (conflict diagrams, signal timing diagrams).
    Intersection & signal timing
  • Coming soon04 · NEX LOS

    Nex LOS

    • Analyzes and evaluates Level of Service (LOS) and delay for road segments and junctions.
    • Applies domestic and international traffic engineering standards (QCVN, TCVN, HCM [Highway Capacity Manual], ...).
    • Automatically generates summary tables of LOS results, v/c ratios and average delay, detailed by movement, lane group and for the junction as a whole.

  • Coming soon05 · NEX SIMULATION

    Nex Simulation

    • Automatically pulls the delay and Level of Service (LOS) results from the Nex LOS module to recreate dynamic traffic flow.
    • Visually simulates the movement of passenger car unit (PCU) traffic through the junction.
    • Exports high-quality video for project appraisal reports.
