Push processing to the edge
Your connected roadway solution will produce a waterfall of data. So start asking some hard questions about your agency's true data processing capabilities now to reduce issues later on. Questions like can your data center handle the added load or do you have enough staff and the right knowledge base?
Edge and fog computing. The answers may mean moving data processing from your data center to where the action is. For connected roadways, that works best anyway, reducing bandwidth usage and latency while empowering real-time predictive apps. That's where edge and fog computing comes into play (read the infamous Westworld comparison here). But it needs to work across standards, be capable of filtering for valuable messages, and be able to apply logic based on rules and analytics.
