Act and Anticipate Hazard Perception Training – AAHPT

AAHPT is a research effort aimed toward developing innovative training strategies for Hazard perception among young-inexperienced drivers.

  • AAHPT is still in its development stages. Nevertheless several experimental phases have already been completed
  • Initial findings concerning AAHPT training methodologies are available, those are constantly embedded into future development directions.

AAHPT principles

  • Intended for novice drivers who have already obtained the basic skills of driving (i.e., vehicle handling and maneuvering)
  • Enriching driving experience in a short period of time (i.e., in a condensed way)
  • Exposure to diverse real life driving situations (see below, residential, sparsely populated urban and inter-city areas)

  • Training- Actual hazards vs. Testing- Potential hazards (i.e., less salient situations)
  • Data driven events-not are defined a priori (i.e., there is no one single master solution)
  • Goal standard of experienced drivers (performance of young-inexperienced is compared to a pool of data obtained
  • Variety of HP measurements

AAHPT variations

  • Active – Participants observe 63 HP video-based traffic scenes and are asked to press a response button each time they detect a hazardous situation.

Participants first observe a movie press a button each time they perceive a hazardous situation. Once, completed a text box appears and they have to specify the reason for their presses.

  • Instructional – The ‘Instructional’ group underwent a theoretical tutorial, where written material concerning HP was followed by video-based examples. Participants were not asked to actively respond to situations, but rather to become familiar with concepts and examples.

Here are two sample slides taken from the Instructional-based training. The first leads to a discussion on different traffic environments and the second shows a specific example of pedestrians in an urban area including tips and information. This snapshot was taken from one of the 63 videos of traffic scenes used in the AAHPT training.

  • Hybrid – The ‘Hybrid’ participants observed a concise theoretical component first (similar to the ‘Instructional’ mode) followed by a shortened active component (similar to the ‘Active’ mode). This mode enables the young-inexperienced drivers to receive both theoretical information as well as to act and respond.

HPT (Hazard Perception Test)

  • Observe 58  HP movies and  press a response button each time they detect a hazard similar way as in the Active training but different movies with less salient hazards (see following images left-training, the hazard (e.g., vehicle) is apparent whereas right-testing the hazard is not apparent ,i.e., potential danger).
