Based on a linear mixed-effects model, we found that the provision of Bus Tracker service does help increase bus ridership. These findings bear out predictions from the cognitive models of behavior and Socio-Technical Systems literature described earlier in the paper. The linear mixed-effects model estimates that, on average, the weekday ridership for the CTA bus route with Bus Tracker service is about 126 more than the bus route without such information, controlling for all other factors. This effect is significant at the .05 level. This may seem to be a modest gain; however, when considering that the ridership effects may expand over time after the lag periods if the learning and adaptation phases are overcome, and additional user benefits that may accrue due to connectivity to related LBS and social media systems, the return on investment from the additional fares raised may more than offset the investment cost, and may lead to new revenue sources. Furthermore, the increased ridership due to the provision of Bus Tracker will also lead to social welfare gains. Thus the benefits of the provision of real-time bus information should not be overlooked.
