The emergence of app-based cab aggregators (CA) has disrupted the urban transportation system and transformed how people make travel choices in Indian cities. These choices impact public transport ridership, vehicle ownership, congestion, parking etc. Understanding the extent of these impacts is critical for efficient transportation planning and policy. Shared mobility platforms such as Ola and Uber have made commuter travel habits trackable and collect real-time data at every point of a commuter’s journey. However, due to lack of access to this data, the impact on urban transportation system are still widely debated, while leaving an immense potential untapped for evidence-based transportation-planning.
