The future’s smart transportation grid and its enabling equipment will communicate routinely with autonomous vehicles and plastics will help make that possible. Plastic shielded network vehicle power stations, traffic flow monitors, stop light timers, lane diversion signals, temporary barriers, travel direction signs, police and fire right-of-way equipment will communicate with vehicles emitting similar signals to maintain safety and flow. Law enforcement, drivers, and delivery persons will share real-time information from the transportation grid gathered as vehicles share information. Speed and frequency of trips by city metro buses, school buses, trash trucks, emergency vehicles, taxis, and autonomous vehicles will donate traffic and congestion data. That data overlaid with real-time CCTV cameras of accidents, delays and police presence will guide improved flow. Soon patterns emerge to shape “predictive” artificially intelligent models of likely congestion, speeds, and delays throughout the grid. Plastic barriers, signs, monitors, etc. will need plastics’ radio-signal transparency. Shielding infrastructure components (the Internet of Things), plastics will be fashioned to resist UV radiation and weather helping keep electronics safe from transmission interference.
