Everyone, at some or the other point, might have been in a situation when they had to call their senior at work to inform them that they will be late, all because of the inefficiency of public transport. Mobility services in cities are deteriorating with every coming day due to traffic congestion caused by the mismanagement of the flow of public transport vehicles. But, that won’t be a problem now as the officials of smart cities have started implementing a new way of mobility, which is termed as mobility as a service. MaaS can overcome the challenge of deciding the optimal route to travel, that is faced by commuters. With active mobility and effective public transport as its base, MaaS offers the best route and travel option as per the need of commuters. And, it also provides an integrated platform to book and pay for the rides. MaaS is transforming travel in a way that probably no one would have thought of a decade ago. The output of experimenting with mobility as a service has gained the attention of investors to invest in it. With increased investment, the MaaS market is estimated to reach a whopping $230.4 billion by the end of 2025, at a CAGR of 32.6%. But, the outcomes of implementing MaaS, its impacts on sustainable mobility, and the need for implementing it may still not be clear to governments and enterprises.
