In the Philippines, one such measure is the introduction of a relatively new public transport mode called the “Premium Point-to-Point (P2P) Bus Service”, which features shorter travel time and lower emission intensity than conventional buses. In light of the significant deficiency in transport emission studies for Philippine cities, this paper presents a scenario-based method for quantifying the potential emission reduction benefits of the P2P bus in Metropolitan Manila. Based on a pro rata mode shift assumption, it is estimated that a 1% mode shift of passengers from existing motor modes to P2P buses would lead to 0.64% reduction of total emissions over selected travel routes in Metro Manila. The analytical method addresses the acute emission data scarcity in the Philippines, and provides early evidence on the aggregate environmental benefits of P2P buses. Extensive sensitivity tests are conducted to verify the simulation results and identify key determinants of emission reduction. The tests confirm the robustness of research findings and further uncover the great potential of increasing vehicle occupancy levels to mitigate vehicle emissions in Metro Manila. Policy implications for enhancing the environmental benefits of P2P buses are provided.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"17 12","pages":"Pages 1302-1314"},"PeriodicalIF":3.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44744118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A promising solution to prevent theft is secured bicycle parking, which offers more protection than regular on-street bicycle racks through secured access, or the presence of an attendant. As cities begin to invest in this infrastructure, practitioners must make difficult decisions about which types of facilities to install, where to install them, and how much to charge for their use. Therefore, this study draws on a large-scale cycling survey (n = 1806) distributed in Montréal, Canada to explore how secured bicycle parking needs vary across different cyclist typologies. To do so, factor-cluster analysis was conducted to generate cyclist typologies. Then the behaviors and secured bicycle parking needs of these different cyclists were established. Four distinct cyclist types emerged: Leisure Cyclists, Summer Cyclists, Occasional Cyclists, and Dedicated Cyclists. Dedicated cyclists were most interested in secured bicycle parking, while occasional cyclists were the least. Leisure cyclists, on the other hand, are willing to pay and walk the most for secured bicycle parking. Across typologies, the top three most important characteristics of secured bicycle parking are (1) being free or low cost, (2) having secured access, and (3) being close to their destination. Respondents are most interested in secured bicycle parking near their work and metro stations. The results from this study can inform practitioners and researchers about the secured bicycle parking needs of different types of cyclists, and in doing so help in the planning for such facilities.</div></div>","PeriodicalId":47824,"journal":{"name":"International Journal of Sustainable Transportation","volume":"17 12","pages":"Pages 1278-1286"},"PeriodicalIF":3.1,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42026873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zone-based optimization is computationally efficient, but it underestimates EC due to spatial biases, even when the zone system is highly disaggregate. We then applied the optimized job-worker assignment to a microscopic travel demand model, assigning workers to jobs of the same job sector at a shorter distance from their home, accounting for multi-worker households. With shorter commutes, there was a substantial shift toward active modes. However, we only observed moderate impacts on total travel demand, with the overall effect dampened due to compensatory behavior between mandatory and discretionary travel.
