A walkway should be designed or assessed with reference to the pedestrian mix using the facility. This is of particular importance in situations where there is a significant atypical pedestrian presence.
An adjustment model is developed to standardize pedestrian traffic flows in the arrivals corridors of airport terminals for use in walkway capacity analyses. The reduction in standard pedestrian flow potential is evaluated through the assessment of relative space requirements for basic user classes. Classes include standard unencumbered pedestrians, pedestrians carrying one piece of luggage, pedestrians carrying two pieces of luggage and pedestrians using luggage carts. Space requirements are defined using headway from the appropriate speed-time headway regression model, and lane width requirements based on the lateral displacement of the pedestrian classes. An illustrative design example is presented.
The use of the adjustment model enables a more realistic assessment of user traffic. Consequently, a walkway designed on this basis will allow pedestrians to maintain acceptable levels of service within mixed platoon flow traffic.
