4. St. Charles County, MO
8 largest cities – there are officially 15 cities and 2 villages within St. Charles County

5. Goals and Objectives Goals
To reduce travel times, delays, fuel consumption, greenhouse gas emissions and incidents, and increase mobility and reliability of travel in St. Charles County
Objectives
Build a communication network to support a county-wide ATMS
Procure and install ATMS software and hardware needed to manage all signals in the county from a centralized location
Develop and optimize coordinated signal timing plans
Supply and install supporting ITS devices such as pan tilt zoom (PTZ) cameras, DMS, count stations, and travel time sensors
Monitor traffic during peak hours

Gateway Green Light – Arterial Management Interface (AMI)
Alternate Route Plans and AMI
$250,000
Complete
AMI - will fund the development and implementation of alternate route plans and an Arterial Management Interface for better and faster traffic incident management on GGL controlled arterials. This project would expand upon the MoDOT incident management plans and Arterial Management Interface already in place along the I-70 corridor through St. Charles County by incorporating the GGL controlled arterials. By incorporating the GGL controlled arterials, it allows greater flexibility and more options for diverting traffic during severe incidents on I-70 and other major roadways throughout St. Charles. A traffic incident management plan would be developed for use by the GGL Operator at MoDOT’s Traffic Management Center (TMC) that would allow for quick response time during severe incidents to keep traffic moving.

Anticipate Completion Fall 2020
Regional ITS Data Sharing (RIDSI) - Phase 1
CMAQ (in accordance with ITS Architecture)
Partnership with MoDOT
Regionwide ITS Data Sharing Initiative - Phase I
In accordance with the St. Louis Regional ITS Architecture, MoDOT and St. Charles County are leading the effort to study, implement, and deploy this data sharing effort among other regional partners. 
This first phase will lay the groundwork for identifying and implementing the technology and data standards whereby participating agencies contribute available traffic and incident information into a central data source. From that source, any agency or organization can acquire the information in a standardized format.
Partial implementation of data sharing and incident data exchange involving MoDOT and St. Charles County will be included in the project. Implementation in other parts of the region will be done in future phases.
Phase I includes 3 components:
Regional Transportation Communications Standardization Platform
Regional Incident Data Exchange
Transportation Archiving and Performance Assessment System

10. Evolution of Communication Design
Deploy a mixed media Communications Network
Fiber
125 miles existing
8.5 miles planned for Phases 4-6
Commercial Cellular
27 locations remaining
Point-to-Point Radios or Leased Lines
Use County Towers
Open to all County / Government Agencies
Federal Regulation delayed County design/deployment, therefore…
Phase 1 deployment used leased TelComm for network backbone

11. Evolution of Communication Design
Modern IP based Open Network Architecture – supports any brand of IP based Layer II or Layer III device
IP Scheme will support 100,000 plus devices
1GB+ Layer III Backbone w/ Multiple Redundant Rings
NTCIP Compliant Arch.

12. ATMS / ITS Management
TransCore TransSuite software selected as GGL ATMS
Same Platform as MoDOT Freeway Management System
NTCIP based
Supports multiple brands and types of controllers and other ITS & ATMS field devices

13. Project Status 340 Signals 90 Travel Time Detectors 45 CCTV
1 DMS (2 more later this year)
11 Radios
91 Video Detection Systems
4 GridSmart (Aldis) Devices
Owned by 10 agencies
MoDOT has over 20 additional DMS
Video Detection are configured to count cars
GridSmart has Count Capabilities – Both now feed count data to MS2 platform

14. Project Status
MS2 – Count Module

15. Performance Measures
16% Reduction in Average Travel Time

16. Performance Measures
Customer surveys will compare public perception versus measured performance
Planning time index will be used which is a ratio of the worst travel time (95th percentile) compared to the free flow travel time

17. Customer Survey
71%
Responded on signalized roadways when surveyed in 2016.

18. Special Events

19. Non-Recurring Congestion

20. Future Phases
Data Sharing

21. Future Phases Emergency Vehicle Signal Priority
Improves response times up to 25%
Reduces the intersection crash rate
CMAQ Funds secured for 2019

22. Future Phases
