A community-based transportation services system. The system includes a community-based transportation network that is comprised of a primary communication device, a cloud server and a parking inventory database. The system also includes at least one communication device communicatively coupled to said network for establishing a parking-spot communication link for allowing a first user to determine the location of available parking-spots for rent. The at least one communication device is also configured to establish a parking-registration link to allow a second user to register and offer at least one parking spot for rent. The system further includes a biosensor collector system communicatively coupled to said network and/or directly to the at least one communication device for establishing a sobriety-monitoring communication link. The data generated by the biosensor collector system allows a first user and a transportation provider to view and monitor the sobriety results of a transportation driver.
