Many megacities, such as Bangkok, are experiencing severe congestion in road traffic and public transport during peak hours. This not only impacts quality of life but also leads to increased emissions, requiring substantial investment in transport infrastructure. An alternative solution presented is using ICT to reform daily activities, particularly commuting and working behaviors, through Mobility as a Service (MaaS) to encourage a shift towards public modes of transport.
Many megacities in the world, especially Bangkok, are facing severe congestion in road traffic and public transport, particularly during peak hours. This situation (a) worsens the quality of life, (b) releases emissions causing air pollution and climate change, and (c) subsequently creates requests for massive investment in transport infrastructure, which easily exceed the budget's limit. Instead of solving the problem by supply-side strategies, applying ICT-based solutions to reform people's daily activities, particularly commuting and working behaviors, on the demand-side is an alternative solution. As a promising solution, Mobility as a Service (MaaS) introduces ICT to persuade people to use public modes of transport. However, modal shift is a partial solution to mitigate traffic congestion. With technological advancements in communication, people become more flexible in their activities in terms of place and time aspects. MaaS should not only induce a transport mode shift but also a workplace shift and working time shift by extending the planning service in daily activity-travel level, exploiting people's flexibilities for an activity's place and time to manage travel demand. This paper proposes the QOL-MaaS as the extended MaaS to support space-time shift of activity-travel and reveals its potential impacts on traffic congestion, quality of life, and CO2 emission.
