The 1997 documentation of the Congestion Management System (CMS) performance monitoring and reporting identified the MBTA Bus Route 66 as one of the routes most in need of improvements. Transit service evaluations conducted for the MBTA also recognized that Route 66 needed corrective action: both crowding and schedule adherence performance measures for this route were measured as poor. The CMS report recognized that one of the causes of the poor route performance was low levels of service for traffic flow on key arterials used by the bus route. Thus, the CMS report recommended conducting a study of the transit/arterial corridor.
The study consisted of developing an understanding of the existing conditions, both physical and operational, and analyzing alternative improvement measures. The following chapter of this report summarizes the existing conditions, including recent measures of route performance and of arterial street and intersection level-of-service. The subsequent chapter presents an overview of the recommendations of the study; for context, the report briefly reviews some of the analyses upon which the recommendations are based. The report concludes with a summary of the issues and recommendations, followed by some thoughts on implementation. The appendices include materials (such as technical memoranda) produced over the course of the study that document in more detail both the existing conditions in the study corridor and the study’s analyses.
