Outline of Final Research Achievements

In order to analyze the effects of monetary incentive measures on the acceptability for mounting "intelligent speed adaptation" (ISA), we conducted 5-month advisory ISA field experiments with 48 subjects (20 elderly) who live in "Zone-30" districts in Toyota city, and then we asked them to respond to some stated preference (SP) questionnaires. The results indicated that the elderly has higher acceptability for ISA. Also, the acceptability for Voluntary ISA that only targets community streets would become greater than 70% (80% for elderly) by incentives of around 15,000 Yen/year. And more, the acceptability for ISA would become greater as the ISA penetration rate become higher, indicating the possibility that the penetration rate may rise exponentially once the penetration proceeds to some extent.
