Tram beats the bus for getting people out of their cars
On 23 February 2005, the Passenger Transport Executive Group (PTEG) published a report (What light rail can do for cities) which finds that New light rail schemes are better at attracting motorists and cutting congestion than improvements to bus services. It reviews the record of the seven operational UK light rail schemes and finds that UK light rail is delivering on ridership, regeneration and modal shift. The report's findings include:
Typically, light rail achieves six times the level of traffic reduction achieved by major improvements to bus services. Around 20% of rush hour light rail users have switched from the car - compared with between 4% and 6.5% for bus improvement schemes. At the weekends, up to 50% of light rail passengers previously travelled by car
