The long-term trend of commuters was less fluctuated than that of all users. The long-term ridership recovery of students was higher than that of all users. Among aggregated attributes, the short-term impact was smaller on “high-frequency users” than on all users: the decrease in ridership immediately after the appearance of COVID-19 was smaller among “high-frequency users” than among all users.

Data collection techniques were conducted through interviews with three different types of respondents. In addition, observations were made to further understand the phenomenon and triangulate the interview findings. The results revealed 3 indicators of parking mismanagement practice: (1) the inappropriate cash flow mechanism of parking charges, (2) the parking signs limitation, and (3) the weak law enforcement. Handling the IPA problem is a part of city development planning that all departments in the local government must pay attention of. The widespread existence of IPAs represents parking mismanagement and local government failure. We call for all the relevant departments and authorities to discuss and collaborate in finding a comprehensive solution to the IPA problem that has impacted Padang's tourism industry. We propose beneficial parking management design, technology utilization, and cashless procedures to overcome this problem.</p></div>","PeriodicalId":100131,"journal":{"name":"Asian Transport Studies","volume":"9 ","pages":"Article 100118"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2185556023000238/pdfft?md5=c6953ea3f6b8dfe7e8f606aadb3cf450&pid=1-s2.0-S2185556023000238-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91987011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study covers 59 roadway projects in developing countries funded by ADB and examines the accuracy of BCA results through four dimensions: frequency, magnitude, correlation, and tendency. We found that under an average project completion rate of 95.33%, the average construction cost overrun for 59 roadway projects is 10.71%, equivalent to USD 71.4 million. Grounded on 23 projects disclosing detailed economic analysis, we discovered a systematic tendency to understate both the present values of cost (18 out of 23 projects) and the present values of future economic benefits (13 out of 23 projects) in <em>ex ante</em> BCA. Furthermore, more than half of projects (25 out of 47) underestimated EIRR, and about 52.17% of them (12 out of 23) understated NPV. Since the underestimation of economic benefits is too small to counterbalance the underestimation of costs, the project EIRR is on average 5.4% lower than the initial expectation. Moreover, we discussed ADB’s choice of the social discount rate, shadow price, and counterfactual base scenarios, which significantly influence the accuracy of BCA results and the reliability of decision-making grounded on BCA results. Lastly, the causes of cost overruns and benefits underestimations were analyzed.</p></div>","PeriodicalId":100131,"journal":{"name":"Asian Transport Studies","volume":"9 ","pages":"Article 100104"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The outbreak of COVID-19 has made the adoption of telecommuting indispensable, reaching an unprecedented level in Japan, bringing dramatic changes in the lifestyles and behaviors of citizens. This study investigates how and to what extent this pandemic-induced telecommuting affected employees’ travel, activities, and residence locations and explores their expectations of post-pandemic life. The data were collected through the online questionnaire survey across three major metropolitan areas in Japan that incorporates a comprehensive set of questions regarding telecommuting implementation and feasibility, lifestyles before and during the pandemic, and expected way of life after the pandemic, and the total of 2045 respondents were collected. The analysis has been done based on revealed preference data considering two time periods i.e., before COVID-19, during COVID-19, and for the post-COVID 19 scenario where stated preferences are considered. In the first step, telecommuting behavior, telecommuting preferences and plans, and activity patterns are estimated based on aggregate sample data. Next, by using the stated preference survey conducted, ordered probit model and mixed logit model are applied to identify factors influencing post-pandemic telecommuting frequency and residential location preference, respectively. The analysis revealed two major findings: telecommuting brought significant changes in multiple aspects of people’s lifestyles and activities that might persist after the pandemic; although determinants that govern telecommuting frequency and residential location choice after COVID-19 may differ across metropolitan areas, commuting/telecommuting frequency is the prime factor influencing residential location decisions. The findings of this research can guide transportation and urban planners in establishing effective travel demand management tools and sustainable urban networks for the new-normal era.</p></div>","PeriodicalId":100131,"journal":{"name":"Asian Transport Studies","volume":"9 ","pages":"Article 100105"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study selected four Asian cities of various sizes under different stages of development to explore how the expansion of rail transport networks and implementation in high-density development of the three TOD policies affect urban accessibility. The results suggest that rail transit network expansion would significantly increase overall accessibility, and TOD policy implementation would further increase accessibility in all cities.

In 1983, the “Taipei City Self-Ordinance for Land Use Zoning Regulation” was introduced to implement a TOD-equivalent design concept even though the term “TOD” was not yet used worldwide. The regulation specifically allowed any new development within a 500 m radius catchment area of a main public transport station which followed Taipei City's urban planning strategies to have a floor area ratio (FAR) reward up to 30% more than the original FAR (Rule No. 80-4). To strategically plan for TOD, Taipei City has developed a comprehensive TOD strategy with four development aspects, ten development strategies and 32 planning principles. The motivation for private developers to follow Taipei City's TOD strategy is the TOD FAR reward. Value capture, an important funding mechanism for public transport infrastructure, has been implemented in Taipei City's TOD strategy to provide a sustainable public transport system. In order to investigate the impacts of TOD strategy in the form of property value uplift at micro and macro levels, trend analysis and difference in differences modelling are constructed. Model results confirm a significant property value uplift at the micro-level. This review has two strong policy uses. First, it can be a starting point to help cities without a TOD strategy to develop a plan. Second, it can help cities, particularly high population density cities, with an existing TOD plan to review their own TOD plan.</p></div>","PeriodicalId":100131,"journal":{"name":"Asian Transport Studies","volume":"9 ","pages":"Article 100094"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49728566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
