Abstract

Intelligent speed adaptation (ISA) has the possibility to be a drastic tool for traffic calming in Japan if they are disseminated once. The aim of this study is to examine the drivers' acceptability for the three types of ISA associated with the types of target roads and some monetary incentive measures. To achieve the aim, a field experiment with Advisory ISA and a SP questionnaire survey were conducted. Based on the field experiment, the effectiveness of the combination of Zone30 regulation and Advisory ISA is presented. Next, by the SP survey and a model analysis, it is revealed that the types of ISA, the types of target roads on which ISA work, and the amount of monetary incentive measures affect the acceptability of relevant ISA. It is finally suggested that a Voluntary ISA working only on community streets has the potential to be disseminated for traffic calming.
