Project summary:

Transitways such as Light Rail Transit (LRT) and Bus Rapid Transit (BRT) provide fast, reliable and high capacity transit service, mostly for longer trips. Transitways have the potential to attract more riders and take a proportion of auto mode share to transit, and hence reduce the growth of auto traffic. Studying such an effect and validating it with real data is crucial for future transit planning and evaluation. Park-and-ride facilities can complement transit service by providing a viable choice for residents without walking access to transit or those who prefer better transit service such as LRT or BRT. Little is known about how park-and-ride users choose the location to park and take transit, considering network topology, park-and-ride types, daily activities, etc. This project will investigate two research questions; 1) how many vehicle miles traveled (VMT) are influenced as a result of transitway projects in their impact zones, and 2) what factors affect the utility of park-and-ride facilities for commute trips in the Twin Cities region?
