Table 1 reports the benefits considered, as well as ranges used as standard predictive evaluation measures.
The study also recommends a range of diversion rates obtained from diverse projects located in Australia, New Zealand and worldwide. These rates are to be used as default values providing the expected changes in mode share from SOV to alternative modes, expressed as absolute percentage points. According to the report, these values “can be used without knowledge of existing mode shares,” which simplifies the approach, although it probably weakens the assessment. The diversion rates are estimated for different travel plans (school, work) in an aggregate fashion, without sub-grouping by location and socio-economic characteristics, due to unavailability of statistically significant coefficients.
