This study introduces an ICT based cost-effective car sharing model named 'GramCar Corporate' for corporates in urban areas in developing countries. GramCar is designed to offer staff bus service in the morning and evening hours and utilize the idle time in the afternoon for delivering healthcare services and healthcare goods to the urban ageing community living in apartments in cities. We carried out a case study on 132 corporates who are living in different locations in Dhaka, Bangladesh but working in the same Grameen Corporate Building complex in Dhaka, by providing them a staff bus service. The study observed the travel pattern (vehicle modes, transfers, financial cost, time cost, physical energy cost etc.) of corporates, the experiences during travel by existing transports and our concept for a car-share service for them. We found that daily average cost for a commercial transport user is 2.3 USD, while 2.5 USD for our shared GramCar Corporate service. GramCar Corporate services reduces the number of transfers and saves 20 minutes from the travel time by Traditional Transport Mode. Through quality delivery of service and well-trained staffs, corporates reported a better travel experience with GramCar and participants reported to have a better psychological condition before starting their work. The paper discusses both the tangible and intangible benefits to the corporates.
