Implications of bus journeys to Pipeland Farm rather than North Haugh



Presumptions made
  • There are 16 buses coming from the North/West of St Andrews
  • Each bus does 4 journeys (base - school and return in morning, base - school and return in afternoon)
  • The school year is 39 weeks
  • The extra distance travelled from North Haugh to Pipeland Farm is 1.8 miles = 2.88 km
  • The extra time taken averages at 7 minutes
  • The lower and upper figures for CO2 emissions are 1 kg/km and 2 kg/km (1)
  • Bus operating costs in Scotland are 1.52 per km (2)

Extra distance travelled (1.8 miles)

Per day
 
64 journeys of 1.8 miles = 115.2 miles = 184.32 km
Per week
 
5 x 115.2 = 576 miles = 921.6 km
Per school year 39 x 576 = 22464 miles = 35942.5 km


Emissions (1 or 2 kg CO2 per km)

  lower figure upper figure
Per day
 
184.32 kg 369.64 kg
Per week
 
921.6 kg 1.8432 tonnes
Per school year 35.942 tonnes 71.884 tonnes


Time saving per pupil (7 minutes per journey)

Per day
 
14 minutes
Per week
 
70 minutes
Per school year 2370 minutes = 45 hours


Assumed cost saving (1.52 per km)
