Valuing Transit Service Quality Improvements
Considering Comfort and Convenience In Transport Project Evaluation

Conclusions:
There are many possible ways to improve transit service quality, including reduced
crowding, increased service frequency, nicer waiting areas and better user information. Because discretionary passengers (people who have the option of driving) tend to be particularly sensitive to service quality, these strategies often increase transit ridership and reduce automobile traffic. Although few motorists want to give up driving altogether, many are willing to drive less and rely more on alternative modes, provided that those alternatives are comfortable, convenient and reliable. Improving transit service quality can therefore provide many benefits, as described in the box below.
Transit Service Quality Improvement Benefits
1. Benefits existing transit passengers (who would use transit even without the improvements).
2. Benefits new transit passengers (who would only use transit if service is improved).
3. Benefits society by reducing traffic problems (congestion,1 roadway and parking costs, consumer costs, accidents, energy consumption and pollution emissions).
4. Benefits from economies of scale (increased ridership can create a positive feedback cycle of improved service, increased public support, more transit-oriented land use, and further ridership increases).
5. Benefits transit agencies by increasing fare revenue.
Current transport evaluation methods tend to focus on quantitative factors such as speed and price, and undervalue qualitative factors such as comfort, convenience and reliability. This skews planning and investment decisions in the following ways:
· Cost-effective transit improvement strategies are overlooked and undervalued, resulting in underinvestment in transit service quality improvements, making transit less attractive relative to automobile travel.
· Automobile improvements are favored over transit improvements, contributing to a cycle of increased automobile dependency, reduced transit ridership and revenue, land use sprawl, stigmatization of transit, and reduced public support for transit improvements.
· Opportunities for modal integration are overlooked, since many transit quality improvements involve improving walking and cycling conditions, or improving connections with other modes.
Techniques described in this report allow service quality to be incorporated into transport planning by adjusting travel time values to reflect factors such as comfort, convenience and reliability. This means, for example, that a quality improvement that reduces travel time unit costs (cents per minute or dollars per hour) by 20% provides benefits equivalent to an operational improvement that reduces travel time (minutes or hours) by 20%. The values recommended in this report are based on extensive research from various sources. They can be used as defaults, although they should be calibrated for specific conditions.
This analysis indicates that high quality transit service unit time costs are lower than driving. In other words, if service is comfortable and convenient, many people will choose transit rather than driving for some trips, even if it takes somewhat more time, since transit travel is less stressful and passengers can rest or work while traveling. However, transit is often uncomfortable, inconvenient and unreliable, resulting in unit travel time costs higher than driving, which dissuades people from using transit.
In a modern, affluent society consumers are accustomed to high quality goods and services. Most travelers place a high value on comfort, convenience and reliability. Motorists are able to express these values by paying extra for more luxurious vehicles, more convenient parking, and sometimes higher quality toll roads. In contrast, individual transit passengers are generally unable to purchase higher quality service. In theory it is possible to offer various classes of public transit service, ranging from inexpensive, basic service to premium priced, luxury service, as is common for some other modes such as air and rail, but in practice there is seldom sufficient demand or political willingness. Since transit service is subsidized and funds limited, and public officials may be criticized if their expenditures appear wasteful, transit agencies tend to provide basic service with minimal amenities. As a result, transit does not satisfy travelers who willing to pay extra for higher service quality - they must shift to driving. Failing to satisfy such demand is a market distortion which reduces economic efficiency and consumer welfare. Ultimately everybody loses, since consumer demand is unmet, transit ridership declines, transit becomes stigmatized, and traffic problems increase.
This is actually good news because it indicates that there are many cost-effective ways to improve transit service quality and increase ridership that tended to be overlooked. Many transit comfort and convenience improvements are relatively inexpensive and provide additional benefits such as improved walking conditions, improving mobility for non-drivers, and support for more compact, smart growth development.
With better evaluation techniques planners can identify policies and programs that more effectively respond to consumer needs and preferences, including transit service improvements.
