Elasticities Database Online
In undertaking its research, BITRE is often required to estimate the likely consequences of changes in market conditions or potential policy changes. In order to do this, it uses estimates of the likely responsiveness of transport to such changes—referred to as elasticities. For example, how is the amount of car travel affected by the costs of running a car, or the price of public transport. To improve how it conducts analysis BITRE has, over the course of many years, systematically collated information on transport elasticity estimates produced by empirical studies. BITRE's database is made freely available here as a resource for transport analysts, policy makers and anyone else interested in transport issues.
At present the database contains approximately 200 separate bibliographic references and 400 table entries, providing a reasonably comprehensive coverage of the empirical transport literature up to 2001.
The database includes full bibliographic references for published (and some unpublished) empirical studies of transport elasiticities. The references are linked to PDF format file(s) listing the relevant elasticity estimates, and may be viewed by following the links in the database.
Accessing the data
The BITRE Transport Elasticities Database provides users with three options for accessing the data:
- Browse References—lists all bibliographic references contained in the database.
- Browse Tables—lists all tables of transport elasticity estimates contained in the database.
- Search Database—permits a multiple keyword search over all fields in the database. The search facility also allows users to restrict the set of fields over which the search is conducted.
While BITRE has taken all due care and skill in compiling the Transport Elasticities Database, it is recommended that users consult the original sources in using the empirical estimates contained within the database. The original sources will contain important information about the raw data, the estimation method used to derive the elasticity estimates and any critical assumptions, which are not necessarily included in the database.
BITRE will update the database from time-to-time, as resources permit. You can help to improve the utility of the database by providing feedback on the design of this site and/or by suggesting new entries to include in the database.
