Table 1: Different previous work done on Auto-rickshaw

Year	Purpose of Study	Major Findings	References
2007	Worked on developing the usage pattern for three wheeled auto-rickshaw in India.	Designed a drive cycle for auto-rickshaw and validated the cycle by Simulink software.	[8]
2009	Worked on micro-hybrid system installation on engine operated auto-rickshaw.	Tested and made a prototype of micro-hybridized auto-rickshaw for India.	[9]
2010	Used solar PV modules in auto-rickshaw as a green power source in normal electric auto-rickshaw.	Designed and auto-rickshaw which was solar assisted and validated the design by ADVISOR software.	[10]
2010	Analyzed on economic and social parameters of three-wheeler taxi service.	Surveyed on 200 operators and 100 passengers, it analyzed the positive and negative aspects of these vehicles.	[11]
2012	Worked on time-dependent plug in hybrid electric vehicle.	Found a compact vehicle with 10.4 KW useable batteries travels 62.5% to 75.7% on battery electricity, depending on charging scenario.	[12]
2012	Worked on the role of auto-rickshaw on sustainable urban transport sector.	Examined the role auto-rickshaw can play in sustainable urban transport sector of India and found a very positive result.	[13]
2014	Worked on Hybrid energy assisted auto-rickshaw three wheeler.	They used plug-in hybrid technology along with PV panel and validated the design by ADVISOR software.	[14]
2016	Worked on the emission factors of auto-rickshaws using real world driving cycle.	They used Indian driving cycle and modified Indian driving cycle for predicting the emissions. In this study real-world DCs were developed for motor cycles and auto-rickshaw.	[15]
2017	Worked on solar assisted tri-wheeler rickshaw.	Made a prototype of a solar driven tri-cycle and tested its feasibility.	[16]
2017	Proposed a solar based micro-hybridized auto-rickshaw.	Mathematically analyzed the vehicle by adding a PV panel with micro-hybrid technology and did a feasibility analysis for Bangladesh.	[6]
