FDOT District 5 – Central Florida Regional Integrated Corridor Management (R‑ICMS)
As SwRI’s subconsultant, EPIC built and supports FDOT-D5’s R-ICMS core— the Information Exchange Network and Data Fusion Environment—coordinating I-4 corridor freeway, arterial, transit, and rail operations.
Introduction
Florida Department of Transportation – District 5 (FDOT‑D5) covers nine fast‑growing Central Florida counties with 4.1M residents traveling 55.6M vehicle miles daily across a complex, multi‑modal network. To coordinate freeway, arterial, transit, and rail operations along the I‑4 corridor, FDOT‑D5 launched the Regional Integrated Corridor Management System (R‑ICMS).
As a subconsultant to SwRI, EPIC designed, developed, tested, integrated, deployed, and supports two core subsystems that power R‑ICMS: the Information Exchange Network (IEN) and the **Data Fusion Environment (DFE).
Challenge
Regional traffic operations relied on disparate systems and agency‑specific workflows, making it difficult to:
- Share real‑time situational awareness across state, county, city, and regional partners
- Evaluate response plans quickly using predictive modeling before activation
- Coordinate multi‑jurisdiction approvals and automate activation via existing ATMS (SunGuide)
- Aggregate, cleanse, and expose multi‑source data for operations and analytics (signals, sensors, transit, rail, modeling, QA)
Solution
EPIC delivered interoperable, map‑centric applications and a robust data platform to integrate regional operations and accelerate coordinated responses.
Information Exchange Network (IEN)
- Map interface & dashboards for corridor situational awareness
- Event & response plan management: detects significant abnormal conditions, presents suggested plans, displays predicted outcomes, and routes approvals across jurisdictions
- SunGuide integration to activate approved plans (e.g., signal strategies) once consensus is reached
- User administration and role‑based access for participating agencies
Data Fusion Environment (DFE)
- Ingests & stores disparate data (state, county, city, regional, and 3rd‑party)
- Transforms & serves cleansed data via a standard API to R‑ICMS and external consumers
- Hosts shared data sources and supports analytics/visualization layers
Key Integrations & Tooling
- Aimsun Predictive Engine (PRE) with a mesoscopic model for plan effectiveness forecasts
- ITSQA quality checks for FDOT and 3rd‑party traffic data
- SunGuide ATMS for signal plan polling and activation of recommended strategies
- Tech stack (selected): ArcGIS Online/Open Data, DNN CMS, Qualtrics, SMTP, JavaScript, C#, jQuery, CSS, HTML5, Bootstrap, Syncfusion, InstantAtlas
Solution highlights
- Map Interface & Dashboards

Insights
≤ 60 sec
from detection to first recommended plan (IEN + PRE)
40–60%
Manual coordination reduction
25–40%
Higher Operator efficiency
Results
- Unified regional operations: Shared situational awareness and coordinated response planning across state, county, city, and regional agencies
- Faster, data‑driven decisions: Predictive outcomes displayed before activation reduce trial‑and‑error and improve plan selection
- Operational automation: Electronic approvals and SunGuide integration shorten time to implement signal strategies
- Open data services: DFE standardizes access to cleansed traffic data for internal users and external applications
- Scalable foundation: Architecture and APIs support expansion beyond I‑4 and incorporation of additional modes and jurisdictions
