We help both drivers and riders save on monthly transit fee, and protect the environment and promote energy safety by reducing gas consumption!

Open Mode Integrated Transportation System (OMITS)

A next generation information infrastructure networking users, vehicles and the roadway system


    Traffic congestion has imposed tight constraint on economic growth, national security, and goods mobility in metropolitan areas. The problem is further exacerbated by the use of vehicles with single drivers. As urban areas must contend with increasing traffic congestion transportation delays, volatile gas prices, vehicle emissions and security threats, sustainability of the transportation system has drawn significant attention from researchers and practitioners alike. The fundamental solution is three-fold:
  • Understand, model and discover relationships between the key parameters of traffic monitoring and control.
  • Improve the ridership of vehicles and thus reduce the number of cars on the road.
  • Optimize the routing and planning of the trips and thus reduce travel time for each vehicle.
  • With the development of wireless communications, Internet services, global positioning systems (GPS), geographic information systems (GIS), and large scale database systems, an excellent opportunity is emerging to transform our transportation system for higher efficiency and sustainability. On the Internet, we can find the static schedule of buses and trains and trace real-time traffic information on major roads. Using cellular phones and GPS, we can communicate with each other about routing and traffic conditions. Although the above-mentioned technologies have catalyzed some excellent ideas in ridesharing systems, existing carpool systems have yet become stable transportation systems that ordinary people would trust and choose at a higher priority. Instead, they are commonly limited to local areas or specific groups of people. The main reasons that have thus far limited the growth of carpooling can be summarized as follows:
  • Most carpooling systems cannot guarantee a ride for riders in a timely manner, so users cannot choose it when under a high time constraint. Carpooling, therefore, becomes secondary choice for routine commute. Most people still keep their cars as a backup, which is a waste of resource for carpooling systems.
  • The charges and savings of carpooling services have not been clearly and fairly specified, limiting potential drivers' and riders' motivation to use these systems.
  • The usage of cell phones for communication between drivers and riders raises concerns about the safety of driving the car, affecting the decision of policy makers and potential users.
  • Many single drivers hesitate to give ride to strangers because of considerations of privacy and the uncertainty of connections.
  • Technical advantages

    The OMITS system is far beyond a carpooling system. Using smart phone apps, it integrates carpooling with the public transit and taxi systems, and provides dynamic transit services. OMITS finds a ride for all rider requests with a lower cost and higher reliability, so that it is a more preferable choice for users. The charge and credit of the ridesharing service will be managed by the system, and no money flows between riders and drivers directly, which makes it possible of retracing and correcting service price for fairness among beneficiaries. Although the OMITS provides a unique, comprehensive information infrastructure that is new to the existing transportation system, some functions and subsystems have been comparable to the following technologies and applications:
  • Private bus services
  • In NYC metropolitan area, some private bus companies have started to provide transportation service for small groups of people between suburban area to the City through Internet and cell phone communication. However, the security and reliability are still a great concern for users, so that they are not popular yet.
  • Google map service
  • Google map can provide transportation direction and traffic report service through internet and Android smart phones. However, the OMITS transit service is significantly different from the Google map service in the following aspects: First, OMITS integrates historic and real-time traffic data for traffic prediction and provides dynamic routing direction with the predicted traffic conditions; whereas Google is still based on the current traffic data. Secondly, OMITS quantitatively provides the real-time speed of the roadway section; whereas Google still qualitatively uses the traffic density as an indicator. Finally, OMITS provides the communication between riders and vehicles through OMITS App, which is beyond Google's scope.
  • Emerging iPhone App in carpooling services
  • Some emerging iPhone apps have been developed for carpooling users. A representative one was developed by Avego Corporation through the Go520 pilot project. The Avego Driver App is used to provide real-time ridersharing and transact the service fee for users. However, the OMITS App and sever program are far beyond a carpooling system.
