ELASTICITIES OF DEMAND FOR TRAVEL

The degree to which travellers respond to changes in the cost of their journeys, as measured by the elasticity of demand for travel, is of importance in modelling their behaviour in the theoretical transport studies used to assess the benefits of proposed schemes. This report reviews and compares values of the elasticities of demand for travel from ten different sources. In cases where the data base is available, the calculations of elasticity are examined and the sensitivity of the values obtained to the assumptions made is tested. The results were: (1) the bus fare elasticity was usually found to be in the range - 0.2 to 0.4. These were the most consistent results in all the findings. The elasticity of bus travel relative to generalised cost lies between - 0.5 and - 1.5. (2) the generalised car cost elasticities calculated were more variable and ranged from - 0.5 to - 2.6. There was some evidence that car travel was more elastic than bus travel, but it is not possible to recommend a single value for the elasticity from the studies examined. /Author/TRRL/
