Text-aided Group Decision-making Process Observation Method (x-GDP)
Joint travel decisions, particularly related to social activities remain poorly explained in traditional behavioral models. A key reason for this is the lack of empirical data, and the difficulties associated with collecting such data in the first place. To address this problem, we propose Text-aided Group Decision-making Process Observation Method (x-GDP), a novel survey methodology to collect data on joint activities from all members of a given…
Going the extra mile
Most leisure activities are carried out jointly with friends or family; therefore, the decision on where to travel is highly dependent on the spatio-temporal constraints of all members of the group. Using data from Tokyo, Japan, this study is the first to develop a joint destination choice model that explicitly integrates such constraints based on revealed preferences of all members. Such a model allows for the derivation of a new measure to quan…
A walker's paradise ain't a driver's hell
This study uses a natural experiment approach to evaluate the causal effect of three regular road pedestrianization schemes in Central Tokyo on traffic conditions in surrounding areas. Cross-sectional traffic volume data collected by the Metropolitan Police Department via traffic counters was used as the dependent variable and causal effect evaluation was done via a difference-in-differences (DID) approach, where the temporal pedestrianization of…
Quantifying willingness-to-walk across varying urban visual contexts using a global-local path choice model
Understanding pedestrians' preferences for network and street attributes is essential for improving walkability, but conclusions from previous studies vary. Thus, to comprehensively investigate pedestrians' preferences, this study conducts a comparative analysis of walking route choices across six areas around stations in the Tokyo metropolitan region. The six selected areas represent a range of typical urban contexts. The focus is on two types o…
Spatial city image and its formative factors
This study analyzes the formative factors of the spatial image of two urban neighborhoods in Tokyo, Japan. Cognitive maps were collected from both residents and visitors, depicting spatial domains as imagined by the names of the neighborhoods. Using street segments as spatial units of analysis, this study analyzed the factors affecting individuals' perceptions of streets. As a result, as well as boundaries such as rivers and avenues, visual lands…
