APPENDIX F
Response 4 25 October 2005
Edinburgh Tram (Line One) Bill Committee
Consideration Stage – Phase 1
Responses to the undertakings in the Preliminary Stage Report
Question
Confirmation, before Final Stage, of whether the double counting error on route 22 affects other roads quoted in Table 4 in Response 19 (as there are large differences on other roads),or whether there are other reasons to explain the differences. In addition updated versions of Tables 4, 5 and 6 in Response 17 (taking into account this error) should be provided.
Response
1 A further review of the bus survey information has been undertaken and we are content that there are no other instances of double counting as highlighted previously. Updated versions of Tables 4 and 5 from Response 17 to take account of the previous double-counting error detailed in Response 19 are included below. It should be noted that Table 6 contained no error but has been included for completeness.

This is likely to be due to a number of reasons:
• General variability associated with traffic surveys; • Daily fluctuation associated with the running of particular bus services; • Updated timetable information incorporated in the model in March 2003, principally reflecting Lothian Buses service at that time and therefore changes to other operator services were not included in the model.
APPENDIX F
3 As outlined in Response 19 notwithstanding the validation error identified previously associated with the isolated survey on Leith Walk, it is considered that the forecasts produced to date represent a robust basis on which to appraise the scheme.
4 Further information relating to the model calibration and validation is provided within Response 5.
