Dynamic bus lanes are only dedicated for buses when and where the buses need them, and otherwise open for all vehicles to use. This report presents the results from a pre-study, investigating the potential that dynamic bus lanes could have as a priority measure for public transport in a Swedish context. Knowledge of situations in which dynamic bus lanes have the highest potential, and their implementation requirements is scarce. It is moreover uncertain how they would affect traffic safety, level of service, user experience, travel time and delays for other vehicles.

A workshop was conducted within this pre-study in order to further investigate plausible user experiences. The results indicate that:

  • bus drivers’ stress levels could be reduced
  • the relative attractiveness of travelling by bus might rise
  • that motorists probably would experience the introduction of dynamic bus lanes as neither good nor bad, as long as the system is fairly intuitive

Technical solutions for implementing dynamic bus lanes exist. A dynamic bus lane system would require development of a system control unit and integration with bus sensors, sensors for traffic flow measurement, variable message signs (to inform road users of the current status of the dynamic bus lane) and traffic signals. The overall conclusion form the pre-study is that dynamic bus lanes could be a useful complementary priority measure for public transport vehicles in Sweden, especially when dedicated bus lanes are not feasible or desirable.
