Design and construction of a truck simulation system oriented to the realization of labour risk prevention, accidents "on mission" for professional drivers. The particularity is that it can reach any location in a country and thus bring the training room to the users.

This system also able to make communication campaigns with the aim of reducing accidents not only in trade but also in non-professional drivers, and can implement within the mobile system, any type of simulator that the customer requires.

The PREVISIM -SICAM system focus this technology development project towards the definition of a suitable training centre with singular driving simulators. Most driving simulators have been developed, some of them available for some years, have neither the physical characteristics nor the orientation to be developed in the PREVISIM project.

The PREVISIM project has tried to define a number of features that allow advantages:

  • Having a system that allows the formation of up to ten conductors together.
  • Having a removable system to different physical work spaces or those considered most appropriate at all times to be designed to be "vehicle mount" in a mobile trailer.
  • The orientation of the simulator to aspects such as increased risk perception and attitude change (variables that explain further the possibility of suffering a traffic accident).
  • Being able to adapt the contents of the simulator to changing work situations, the special characteristics of the company (type of route, etc.) and what different guidelines and laws determined.
  • The adaptation of the system to different types of vehicles (lorry with variable trailer, with different loads on the trailer, bus, etc).

A. Description of the structure (hardware).

The PREVISIM - SICAM system is implemented on a trailer, which can be displaced by a truck (not included) but approved, for travel on the roads of any country. Work zones containing this lorry are:

  • Trainer Post and briefing area. This focuses on the front of the vehicle with a dimension of 1.60 m x 4.60 m and in which a central control station for the instructor and a small room "briefing" for commentary and personal evaluation of the exercises and tests developed by drivers are located. It may also be used as a meeting room.

The material in this area is basically a checkpoint to the instructor that include a computer with graphics capabilities and three output channels where you can individually control each of the positions and even replicate their simulation output a given time.

Also in this area a projection screen of 160x140 and an LCD projector (1024x768 pixels resolution and 2000 Lumens) is positioned to be used as a mechanism for review and/or simulation exercises explanation and demonstration classes.

  • Drive Simulation Area. This area consists of 10 seats twin driving simulation located in the extended area of the truck "Paddock" with dimensions of 9m x 7m. Each simulation positions belong to a real truck cabin and features a triple projection system, reconfigurable control panel, steering wheel with force feedback, armchair conductor, accelerator pedals, brake and gearshift system sequentially.

Ten driving simulation stations are interconnected via a high speed network GigaEthernet order to support collaborative simulation; network also extends to the post of instructor and exam room in order that from this position can be controlled all posts simulation.

  • Virtual classroom area and office monitoring. On the top floor of the container, connected to the ground through an internal staircase, the virtual classroom area has a projector for the realization of the theoretical part of the course and group discussion skills carried out is, for by motorists during the simulation process . Next to this, in the front, is the office of track activity, by preventers and groups, without interaction with the students of the course.

B. Description of the software and training system.

The system comprises a number of software and instructional design elements that are adapted to the hardware elements.

From the instructor module is allowed from the instructional programme, set training sessions for each session. Furthermore runtime allows controlling the various posts simulation exercises to start or finish, modify the conditions of implementation introducing unexpected events (rain, fog, car skipping a traffic light, animals on the road, breakdowns, etc.) or monitor specific actions each individual. The post also offers instructor evaluation software and "briefing" that allows you to monitor and review the actions of each user in order to influence the same problems, or peculiar situations worth to redisplay.

The supplied software package is able to respond to diverse groups of settings:

  • Initial state of the vehicle (Vehicle model to use, system availability ABS, ASR, fuel, loading conditions, tire wear, etc.).
  • Initial vehicle location (Interurban scenario, mountain or urban, starting point, rail type).
  • Type of pavement (asphalt firm with many/few/no irregularities with high /medium /low adherence).
  • Traffic configuration (traffic density and mean flow velocity).
  • Weather and visibility (start time of the year, time acceleration factor, conditions of sun, snow, rain, wind, fog) conditions.
  • In addition, during an exercise in defining the position of the instructor, the possibility of including different types of events, namely incidents, breakdowns and advanced monitoring.

The instructor can affect the simulation session adding on -line new events not included in the original definition of exercise on development as well as provide some microscopic traffic control around the simulated vehicle.

Thus, in a simulation session may include incidents that test the capabilities of the driver in situations that could occur any day on the road.

PRESEVIAL managed by the Foundation (Foundation for the Promotion of Culture of Prevention for road safety in the Valencian Community) is currently intended for conducting courses on prevention of occupational risks for traffic in Valencia.

Made with funding from the Foundation CDTI (Centre for Industrial Technological Development) and the IMPIVA (Institute for Small and Medium Valencian Industry), on the DATS Research Group in collaboration with the ARTEC Research Group, Lander and University of Valencia.
