The Refuse Data Collection System (RDCS) was developed to make the world a greener community and to help municipalities greatly reduce the debt loads that are related to their solid wastes collections. The system will also help the users completely remove hazardous materials and plastic bags from landfills while ensuring the implementation of a quality recycling program that can achieve reclamation results that rise above 90% (instead of the dismal 35% recycling rates claimed by the EPA).

The Early Warning Control System (EWC) developed by Transportation Technologies will finally put an end to vehicular and pedestrian accidents at Rail Crossings. The camera and control sense assemblies located at each crossing constantly communicate crossing status to an approaching locomotive and to a central command control point. The EWC also informs all vehicular and pedestrian traffic of an approaching train with audible and visual alerts so that there will be no more surprises (the EWC also communicates train status to an automobile, truck or school bus via the vehicles radio).
