Image gallery driver training simulator software:

The driving simulator generates three images: there's a channel for left, center, and right, each on a separate monitor. In the images below, only the center channel images are shown. The images concern systems for countries where driving is in the left lane. Carnetsoft offers software for various countries, both for left lane and right lane driving.

Driver training simulator

Carnetsoft develops car driving simulator software for driver training, scientific behavioural research and clinical applications, such as testing of driver fitness and measurement of brake reaction time. The very complete driver training curriculum contains all the lessons your trainee needs to become a skilled and safe driver. It contains lessons in vehicle control, including gear changing, lane changing, use of indicator and visual scanning of the environment. This makes it suitable for the initial phases of learning to drive a car. But also complex traffic behaviour is trained, including entering highways, negotiating roundabouts, application of priority rules, driving on motorways and in villages and towns with pedestrians and unexpected events. Training in fog, rain, snow, sun blinding and night driving are also an important part of the curriculum. The emphasis is on learning to drive safely.

The specifications of the hardware and software can be found here. This allows you to buy your own computer, displays and steering wheel and pedal set, and install the software tourself, or with a little help of Carnetsoft. An overview of the prices can be found here.


The driver training modules focus on two aspects that are of utmost importance in driver training:

- task automation: repetition of driving tasks, such as gear changing, lane changing, use of the indicator, approaching a junction, application of priority rules, negotiating roundabouts etc. This makes sure the student practices all these tasks sufficiently which results in task automation. When essential tasks are performed automatically, without requiring too much attention, the driver can focus and anticipate on unexpected events and spread the attention to a wider view of the surroundings. This is the main factor that makes driving safer. A better skilled driver is more aware of hazards in the surroundings, looks farther ahead, scans the surroundings more frequently and checks the mirrors regularly.

- visual scanning: scanning is checked by the virtual instructor continuously, via a head tracker that evaluates whether the driver has checked the mirrors, and looks to the left and right when approaching an intersection, or checks the shoulders when changing lanes. Visual scanning is an important part of safe driving that must be integrated in the driving task and become a second nature of the driver. Beginner drivers often lack the attentional resources to scan sufficiently which is one of the most important reasons why they fail their driving test. As drivers become more experienced, and the task requires fewer controlled and conscious attention because of task automation, more attention is allocated to visual scanning of the mirrors and the surroundings which results in safer driving. The driver training curriculum in the driving simulator integrates visual scanning in the driver training from the start which is one of the reason why this type of training is so effective.

These aspects are where a car driving simulator is better at, compared to the usual method of driver training in a learner car. Feedback is consistent, the virtual instructor in the driving simulator checks continually for driving errors. Also, the quality of instruction and feedback is high for all students, and the reports, generated by the student assessment system are detailed and present a good picture of student progress.

All important aspects of learning to drive a car are covered. In contrast to some other driving simulators, in the Carnetsoft driving simulator, the emphasis is not just on learning vehicle control: also traffic interactions, unexpected hazards, special circumstances (night driving, rain, snow and fog) and safety awareness are an inportant part of driver training.

The complete set of software modules for driver training, including the 3-display surround runtime simulation software, costs €1500. This is only a fraction of the price of other comparable professional driver training software that you will find in the market.

Research driving simulator

The research driving simulator software has been used in numerous experiments by universities and research institutes. It enables the researcher to prepare and perform behavioural experiments into car driving and human factors experiments in a minimum amount of time. The type of experiments that have been done range from experiments on the effects of alcohol, drugs and fatigue on driving behaviour to experimens on workload and in-vehicle devices. The complete research driving simulator software suite costs €2500. This is substantially lower compared to other research simulator software products.

This software was especially designed to create and run car driving behaviour and human factors experiments. Behavioural experiments can be created by the researchers themselves or the technical staff and results can be analyzed quickly. Here are a few examples of recent experiments conducted with the research driving simulator software :

  • studies on the effects of drowsiness and fatigue (time on task) on steer reaction time,
  • effects of distraction on brake reaction time,
  • effects of peer pressure on speed compliance,
  • a gap acceptance study,
  • a study on effects of secondary tasks on perception of roadside information,
  • effects of alcohol on steer- and brake reaction times,
  • a study on fundamental processes of workload and selective attention while driving, etc.

Behavioural experiments can be designed in a number of different fields:

  • Experimental Psychology (studies on attention, vigilance, workload, perception),
  • Social Psychology (measures to influence driving behaviour),
  • Clinical Psychology and Psychiatry (effects on exposure on phobias and anxieties while driving),
  • Human Factors research (interfaces, secondary tasks, workload),
  • Pharmacology (effects of alcohol and drugs on behaviour), studies on training and learning, studies on driver fitness,
  • etc.

Assessment of fitness to drive and clinical applications

Most existing practices to assess the fitness to drive after a CVA, at older age, sleep apnea or with various neurological conditions, often lack reliability and validity. In order to assess fitness to drive in a reliable and valid way, more is needed than the traditional eye tests and tests of urine samples and standard neuro-psychological tests. Simulator tests can be a valuable addition to the set of diagnostic instruments to test fitness to drive. The clinical module consists of a number of standardized fitness to drive tests that vary from measuring the brake reaction time to the measurement of workload in driving situations with varying complexity. Also, a number of simple and short tests assess steering reaction time and brake reaction time in controlled conditions while spare information processing capacity is measured. The fitness to drive tests have been designed in such a way that the risk of simulator sickness is as low as possible.

The fitness to drive tests have a number of advantages over the traditional methods of assessment:

  • ecologically valid: the tests measure behaviour that is very close to real driving
  • reliable: a large number of measurements are made in controlled conditions resulting in a low standard deviation of the measurements and a reliable measurement of driving related skills
  • practicality: the tests are easy to administer and don't take much time

The clinical modules plus runtime driving simulator software is available in 2 versions:

  • a 4-display version (3 rendering channels/displays for 210 degrees horizontal field of view + 1 display for the user control interface). The price of this software licence is €1000.
  • a 1 display version, with a 70 degrees horizontal field of view. The price of this software licence is €750. Also the hardware requirements are lower in this version, so the costs for hardware is substantially lower as well. Also, 1 monitor requires substantially less space on your desktop compared to a 4 display system.
