Car Share and Car Clubs: Potential Impacts (Final Report)
Appendix IV: Assumptions used in compilation of Tables 3.1-3.3
General assumptions
- Current prices include petrol at 81 pence per litre.
- A short journey is a 8.5 mile round trip over 3 hours.
- A long journey is a 100 mile round trip over 8 hours.
- High user of a car is estimated to drive 10,000 miles per annum and make an average of 400 journeys, a high user of a car club is somebody who uses the club 150 times per year, a high public transport user is somebody who uses it five times per week, 45 weeks per year.
- Low user of a car is estimated to drive 1,000 miles per annum and make an average of 100 journeys, a low user of a car club is somebody who uses the club 24 times per year, a low public transport user if somebody who uses it twice a week, 45 weeks per year.
Car Ownership
- A new large car is estimated to cost £15,000 paid off over 4 years at 8.7% APR.
- A new small car is estimated to cost £7,500 paid off over 4 years at 8.7% APR.
- A very old car is estimated to cost £800 paid off over 4 years at 0% APR. No depreciation.
- Other fixed costs are : VED and insurance, breakdown cover and depreciation based on the average figures provided on the AA website.
- Running costs are oil, tyres, servicing, repairs and replacement, plus petrol in pence per litre. Figures are based on the averages provided on the AA website. Petrol has been used as a guide for simplicity, clearly the principles would be the same for other fuels.
Car Sharing
- The petrol portion of the cost has been divided by two as it is common for only theses costs to be shared. In reality, savings may be less than suggested here as not all journeys will be shared.
Car Hire
- "Cheap" is based on Easy Rentacar prices plus fuel costs.
- "Typical" is an average of Budget and Avis prices plus fuel costs.
- A small car is a Corsa or equivalent.
- A large car is a Vectra or equivalent.
- Figures are for weekdays - it is not possible to hire for a single day at the weekend in many cases.
- Rental cost is unaffected by changes in car purchase cost.
Car Club
- Costs of the car club depend on the scheme joined, the type of vehicle used and whether or not you are classed as a low or high user. High users pay a higher membership fee, but benefit from a reduced mileage rate and from having the initial outlay spread over a number of journeys. The costs used are based on the average cost structures published by CCSN and assume use of a mid range vehicle.
- Membership costs are assumed to be unaffected by changes in car purchase costs.
Public Transport
- Season ticket is a METRO (West Yorkshire) card which covers Rail zones 1-3 and travel throughout the county by bus (£530 pa).
- For journeys without a season ticket, an average of the peak and off-peak charge has been used, based on two one way tickets using a combination of bus and rail.
