ABSTRACT
A B S T R A C T This chapter describes the methodology used in Saitama, Japan to tackle traffic bottlenecks in the vicinity of bus stops. Two different kinds of tracking data-probe car data and bus smart card data-were utilized to study which infrastructure improvements around bus stops are most in need. Probe car data are used to assess where buses block the traffic, while smart card data help to understand the temporal distribution of passenger demand. It has been found that a simple analysis of smart card data can be a useful and powerful tool in assisting local authorities to strategically decide where to invest their resources, limited as they are.
