Using detailed data on travel time for buses, we have illustrated congestion problems for selected bus routes in Bergen, and investigated the effects of measures for improving public transport travel time and reliability. We demonstrate that congestion problems can be documented using such data, and that different measures of congestion and reliability largely give the same impression. The results show that active signal prioritization (ASP) in signal-controlled intersections has had a significant effect on travel time of buses at two intersections at Haukås north of Bergen. A new bus lane in the same area does not appear to have had any effect. We also find no effect of the project for Route 10 between Gyldenpris and Wergeland, where a number of minor improvements had been made. Simple cost-benefit analyses indicate that ASP gives positive net present value in one or three intersections, depending on how travel time gains are valued.
