eTaxi is a proposed mobile taxi booking application that aims to address common problems with traditional taxis. It would allow users to book rides through a mobile or web app, track their taxi via GPS, and pay safely through the app to reduce cash transactions. The app also incorporates security features like recording trips and including an alarm button. It proposes using a rating system to collect feedback and improve driver performance over time. Key stakeholders involved include passengers, taxi companies, mobile operators, and payment providers. The goals are to provide a safer, more convenient taxi experience for passengers and increase productivity and revenue for drivers.
