Bath Trams,
Nottingham is said to have 6M fewer cars per year on the city’s roads since the tram, against rises elsewhere. As NET has about 18M trips per year, 6M would represent at least 33%, if each car had only one occupant, so the real figure is probably more like 40%, and even more if the increase in car use elsewhere is taken into account. NET was designed with P+R as a major component, with over 5,000 free parking spaces.
Regards,
Dave Gibson.

The PTEG report gives 19% for Croydon (16% drivers and 3% passengers).

Comments from Prof. Lewis LEsley:
Professor Lewis Lesley – BSc, AKC, PhD, CEng, FRSA, MICE, FCIT, MTPS) ljslesley@aol.com. Professor Lesley spent bulk of his academic career studying how to get people to use buses rather than cars.
” 2.2 pteg recently published a review, by consultants Steer Davies Gleave (SDG), of the record of light rail in the UK. The report (“What Light Rail can do for Cities”), found that UK light rail is popular, with all schemes operating at, or near, capacity at peak times. Overall there has been a 52% increase in patronage since 1999 with significant flows being carried outside the rush hours. This increase has come despite significant increases in fares, and at a time when patronage of the bus network outside London has fallen.”
3.2 This helps to explain the high modal shift that UK light rail has achieved, with about 20% of peak hour light rail users having previously travelled by car. At the weekends modal shift can be as high as 50%. Reductions in road traffic of up to 14% after the introduction of tram schemes have been recorded.
4.7 Light rail’s advantages over the bus alternative are reflected in the much higher levels of modal shift that light rail achieves. As set out in para 3.2, peak hour transfer from car to tram is consistently around 20%. This compares with estimates of between 4% and 6.5% resulting from significant improvements to bus corridors. Finally, as the SDG report shows, improvements to bus services (often perceived as potentially temporary) do not have the same catalytic effect on urban regeneration and city image that can be triggered by the tangible and permanent commitment to an area that light rail represents.
6.2 The bus will remain the mainstay of public transport provision in the city regions and new forms of guided, high quality and tram-like bus systems are being pioneered by the PTEs. However light rail has clear advantages on busy corridors where its greater capacity, speed, quality and reliability have led to far higher levels of modal shift than improvements to bus services have hitherto come close to achieving.

Comparative Mode-Shift to Quality Bus Schemes
4.33 While the effectiveness of light rail in attracting car users has been clearly demonstrated, the ability of bus-based schemes to affect significant mode shift in the UK remains largely unproven. A comprehensive study of existing schemes found overall potential passenger uplift from bus quality initiatives27 ranged from between 4.1% and 6.4% in the medium term (i.e. 3-5 years after implementation of all measures).
……………………
4.37 These responses are encouraging but, in comparison to light rail, suggest a much lower level of car transfer: • Typically, around 20% of peak light rail users have been found to transfer from car. In a peak hour, a typical system operating at, say, 6tph would have resulted in c.240 cars per hour removed from the road network. • Similarly, 20% of new bus users in a quality corridor might transfer from car and a 20% uplift in total demand might be achieved. At an overall level of service of, say, 30bph then c.40 cars per hour would have been removed from the road network.
