HFN provides human factors guidance on design based on site visits and observations and based on scientific research and basic human factors principles concerning driver workload, expectancy and error for all road users, including drivers, cyclists, and pedestrians.
HFN conducts assessments of the operator workspace and the design of work for operators of buses, light rail transit vehicles, and subways. Key considerations include operator workload, line of sight constraints, and the arrangement of controls and displays. HFN also provides assessment of transit stations based on a user-centred design approach.
HFN carries out road safety audits and in-service road safety reviews. This work typically involves carrying out field reviews to observe the facility from the perspective of drivers, pedestrians, and cyclists and different times of the day and under different lighting conditions.
HFN provides advice and scientific research on legibility, comprehension, message length, operator response and sign location related to changeable message, street name, tourist, advertising, transit information signing, and complete wayfinding systems.
