Transportation agencies have increasingly turned to advanced technologies and intelligent systems to improve road safety. These systems collect real-time information about roadway and traffic conditions and deliver that data back to travelers through actionable alerts, known as Traveler Information Messages (TIMs).
At first glance, this may seem straightforward. Every state already operates its own traveler information system, typically composed of changeable message signs (CMS) and web- or app-based 511 systems that share details about weather, traffic, construction, incidents, and road closures.
However, CMS installations are limited in number and location, and drivers cannot safely browse websites or apps while on the road. The situation becomes even more complex for trips that span multiple states, as drivers may navigate different systems with varying formats, interfaces, and data quality.
While these systems are excellent tools for trip pre-planning, they are less effective at providing real-time updates for the next few miles ahead, the kind of information that can make the difference between a smooth journey and a sudden, hazardous situation.
Unifying Data with SDX
Recognizing this challenge, transportation agencies have begun implementing in-vehicle, connected vehicle-based TIMs, which bring critical, location-specific updates directly to drivers through their vehicles. Building on this vision, a coalition of transportation agencies along the I-80 corridor launched a major initiative to unify their data into a single, standardized platform: the Situation Data Exchange (SDX). This collaborative effort integrates data from 11 states, creating a consistent source of real-time roadway information across the corridor.
Each data feed is parsed through custom logic developed for Corvus, a platform that processes and creates timely TIMs. Once generated, these messages are published to the SDX, where they can be accessed by third parties and Original Equipment Manufacturers, and delivered to drivers in near real-time.
The I-80 data integration initiative is a significant step toward a more unified and intelligent transportation network that enhances roadway safety and lays the groundwork for future connected and automated vehicle technologies.
