A comparison of the λ parameters for all activities for each transportation mode is shown in figure 13.2. It can be seen that the λ parameters are similar for journeys made by walking, cycling and private motor vehicle. However, the λ parameter for travel by bus is significantly lower. This indicates a greater proportion of trips made by public transport are of longer duration than the other modes, and perhaps more importantly, relatively few short duration trips are made by public transport compared with other modes.
