Problem definition: Congested roads badly affect public transport services especially buses. During peak hours thousands of passengers travelling by bus get stuck in traffic jams. Priority lanes for buses prioritize buses when they are stuck in traffic. The measure includes segregation, traffic management, traffic signal control and bus stop improvements. Moreover an innovative bus system operates with a reliability of trams in congested areas, and the flexibliity of buses, where it is needed.
- Dedicated or segregated lanes for buses - Priority for buses at intersections (traffic light management)
- High quality buses and stops
- Additional corridor improvements, accompanying the bus service [2,3]
Implementation examples
Example UK:
- Bus Priority Measures 'Greenways' Edinburgh
Example France:
- Busway system, Lorient and Nantes
Example Hungary
- Bus Priority Scheme, Budapest
Objectives of TPM
- Facilitating the provision of a faster, more frequent and more reliable bus service
- Creating better conditions for cyclists
- to reduce travel times for public transport
- to improve public perceptions of the quality of the public transport service
- to increase public transport usage
- Improving crossing facilities for pedestrians, including disabled people and people with reduced mobility providing adequate loading and parking facilities for businesses
- Improving safety for all classes of road users including pedestrians[2,3]
Choice of transport mode / Multimodality
Improving public transport service and worsening traffic conditions for car traffic may influence car drivers to choose public transport instead.
Origin and/or destination of trip
The measure basically does not influence the origin and destination of the trips however an advanced system may cause limited (or stronger) influence on trip choice. (Destinations along prioritized corridors will become more attractive and other areas (far away from these corridors) will be negatively influenced.)
Trip frequency
The measure does not influence trip frequency.
Choice of route
Car drivers often choose alternative route to avoid the bus corridors, and public transport will switch to priority lanes
Timing (day, hour)
One main advantage of the system is the ability to ignore peak-hour congestion. Therefore high level of service can be offered during the whole day.
Occupancy rate / Loading factor
Often high capacity buses are used, with higher occupancy than conventional bus services.
Energy efficiency / Energy usage
In most of the cases clean engine buses are used, which influence the energy efficiency significantly.

Implementation phase
Inconveniences during implementation phase, due to traffic restrictions.
Operation phase
Benefits are definitely delivered as soon as the system starts operating
Summary / comments concerning the main impacts
Bus service becomes more reliable, travel speed increases, travel time reduces, delays become unlikely, while private car traffic may be affected badly due to possible reduced numbers of lanes. [2]

Overall impacts on social groups
Implementation phase
Implementation costs depends on the volume and complexity of the system. A totally segregated (tram-like) system may cost very high, but generally it is a cheap and cost effective solution.
Operation phase
Operation is similar to a conventional bus service, while cheaper than a tram system.
Summary / comments concerning the main impacts
The measure offers the benefits of a tram-like system. Reliability on congested reads, and flexibility where neede, while the costs are definitely lower, about one third, comparing to a tramline. [2]

Implementation phase
Operation phase
Summary / comments concerning the main impacts
Reduction of car traffic along the corridor improves the safety of all the social groups (road users / traffic participants). Accessibility of public transport (bus services) improves due to new bus lanes and more bus services will ask for more bus drivers which increases employment. [3], [4]

Summary / comments concerning the main impacts
Reduction of air pollutants and noise emissions along bus lanes (which used to be open for traffic and now are only available for buses), due to decrease in car traffic [1].
