Open-Source Taxi App

According to this website, there are 300 million users of taxi apps with Uber and DiDi responsible for 150 million of those users. The taxi app market size is expected to be $283 billion by 2028. Often these apps take a large portion of the fare (a lot of information is available for this for example [1], [2], [3]). Some taxi companies take a smaller commission e.g. DiDi takes about 20% (source), compared to Uber and Lyft's 40 to 60% (source) and this shows its possible to take less commission. Many people believe that open-source taxi apps with more transparent and fair business models should exist with minimum fees that are fully and available for examination/audit. Many have wondered and inquired if such apps exist ([1], [2] etc). The goal of this research is to determine:

• what open-source taxi app alternatives exist, to what extent they have been successful and if not, the reasons for not achieving success and the challenges they have faced
• what it would take to make such an initiative successful from a technical, legal, human resources and operational perspective
• if we should take an existing solution and modify it, or develop from scratch
