Three new papers on para-transit in Asian cities
Three papers on para-transit in Asian cities (We newly call it “LAMAT – Locally Adopted and Modified Advancecd Transport”) have been published in Journal of EASTS:

Stated Preference Analysis for New Public Transport in a Medium-sized Asian City: A Case Study in Malang, Indonesia,
Journal of the Eastern Asia Society for Transportation Studies, volume 11, pages 1451-1466, 2015.
doi={10.11175/easts.11.1451}
This study analyzes citizens’ travel choice behavior in a medium-sized Southeast Asian city to observe their intention to use new public transport. We selected Malang in Indonesia as a case study. A travel behavior and intention survey including stated preference questions was conducted with university students. The results of the latent-class model of commute mode choices show that respondents could be divided into “cost and delay time” and “travel and access time” oriented classes. Respondents who were likely to convert to new public transport modes were male, had a higher income, and were interested in new public transport. The estimation results of the scheduling choices model confirm the significant difference in the sensitivity to recreation time between recreational activities.

A Comparative Study on Road-based Urban Public Transport Policies in Six Asian Countries from the Viewpoint of Governance, Urban Planning, and Financial Aspects,
Journal of the Eastern Asia Society for Transportation Studies, volume 11, pages 1433-1450, 2015.
doi={10.11175/easts.11.1433}
In this study, we conducted an international comparative study on road-based urban public transport policies in six Asian countries: Cambodia, Indonesia, Japan, Philippines, Thailand and Vietnam. We paid attention especially to governance, urban planning and financial aspects as important background factors for considering road-based urban public transport policies. We found that the assignment of the administration on road-based urban public transport was different in the six countries. Among three urban planning measures, zoning for Transit Oriented Development and land development permission were implemented in all six countries. However, coordination with public transport through these two mechanisms was not necessarily established. In relation to financial policy for public transport, the six countries share many common policies. The exception in terms of the subsidy to paratransit was Japan where paratransit mode serviced in the area with serious population decrease.

Road-based Urban Public Transport and Paratransit in Six Asian Countries: Legal Conditions and Intermodal Issues,
Journal of the Eastern Asia Society for Transportation Studies, volume 11, pages 227-242, 2015.
doi={10.11175/easts.11.227}
In this study, we present an international comparative study on urban public transport and paratransit in six Asian countries. The paper focuses on benchmarking legal aspects and intermodal issues among existing urban paratransit, aiming for a better future policy in fulfilling the need of urban population growth. Results indicate that many modes are actually has not yet been legalized in the six countries. From the typology of typical paratransit modes, it is found that there are still paratransit modes with fixed route that might respond to the travel demand enough for sustaining route service if the vehicle size is minimized. Finally, there are many cases where BRT and other public transport projects face the issue of restructuring of existing public transport network mostly with bus mode. Development of intermodal facilities is considered as one of the solutions for overcoming the issue. It is also noted that common ticketing system, or integration in terms of systems, should be regarded as an important measure for promoting the integration.
A New Research Paper on Travel Time Variability
A research paper on travel time variability has been published.
“On the cost of misperceived travel time variability”
By Yu Xiao and Daisuke Fukuda
(Transportation Research Part A: Policy and Practice, Volume 75, May 2015, Pages 96-112)
Abstract: Because individuals may misperceive travel time distributions, using the implied reduced form of the scheduling model might fall short of capturing all costs of travel time variability. We reformulate a general scheduling model employing rank-dependent utility theory and derive two special cases as econometric specifications to study these uncaptured costs. It is found that reduced-form expected cost functions still have a mean-variance form when misperception is considered, but the value of travel time variability is higher. We estimate these two models with stated-preference data and calculate the empirical cost of misperception. We find that: (i) travelers are mostly pessimistic and thus tend to choose departure times too early to achieve a minimum cost, (ii) scheduling preferences elicited using a stated-choice method can be relatively biased if probability weighting is not considered, and (iii) the extra cost of misperceiving the travel time distribution might be nontrivial when time is valued differently over the time of day and is substantial for some people.
