G'Val (G'Tun & G'Road)

Real-time 3D Visual Interactive Simulation of Traffic for Road and Tunnel Management

G'Tun & G'Road bring a realistic, interactive and evolving visual simulation. It can be completely parametrized and it is based on precise business information and on the experiment of professionals. It brings you assistance at each phase of your project for training , design and communication.

TRAIN

• Realistic simulation exercise
• Exercise on the real operational HMI
• Edition of choice scenarios
• On-line trainer intervention
• Editing a detailed report of end evaluation

DESIGN/EVALUATE

• 3D real-time simulation
• Based on specific business data
• Taking in to account your project specifics
• Operating rules and equipment validation support
• Assessment Tool of proposed solutions (developments or changes)
• Impact analysis of operational events thanks to a real-time reporting process

COMMUNICATE

• A powerful communication medium facilitating discussion around your project
• Generation of easily releasable video clips

G'Tun® & G'Road® are composed of 3 separate modules :

• The visual simulator: it simulates the traffic in a realistic and interactive 3D environment. It generates traffic incidents, simulates visually the behaviour of multiple types of field equipment, modifies their implementation and / or characteristics and can provide images from fixed or mobile cameras into the virtual 3D space.

• The trainer module: it permits the user to ‘pilot’ the simulator in parallel to operating tools used through the HMI. It can activate a whole series of scenarios and incidents as well as generate a variety of reports. This module enables the trainer to control the different parameters of the simulator.

• The SCADA interface : this allows the simulator to exchange data with the SCADA Data Base through an OPC protocol. These data come from the different sensors simulated within the project (LCS, ADI, door etc.) and the control orders from the SCADA or Trainer HMI (started accelerator, closed barriers, VMS etc.)

A library of street furniture, vehicles and characters that are easily integrated in a realistic 3D environment allows the user to produce a visual simulation which delivers video images comparable to that of the real cameras from Road or Tunnel.

Some examples of scenarios :

• Generation of a slow moving vehicle at any KP
• Generation of an accident between a 2 LV, any KP, lane to choose
• Generation of a disabled vehicle, any KP, lane to choose
• Generating a smoke scenario, any KP, lane to choose
• Object on a roadway (packages, wheel etc.), any KP, lane to choose
• Rescue arrival, repairman, patrol, police…
• Ground marking
• Contra flow vehicle
• Wandering animal
• Possibility of creating multiple scenarios – via the Scenario Editor

In the simulator every vehicle has an embarked intelligence.
