Adverse Side Effects
The key adverse side effect resulting from ride sharing is likely to be
abstraction from public transport services. In a commercial environment,
any substantial reduction in fare box revenues is likely to cause a reduction
in service levels. A reduction in service levels is likely to have negative
impacts on equity and accessibility. Additionally, if increased car use
results from the reduction in public transport services, the negative
impacts of car use will increase, and for low income households forced
to purchase a car, poverty will become a more serious issue.
