Corpus Christi

The newest addition to Castle Rock's roster, Corpus Christi Regional Transit Authority uses Castle Rock's proprietary Modes-Update software to generate GTFS files which they then publish to Google Transit.


Idaho Transportation Department (ITD) selected Castle Rock to build and deploy its first 511 phone service and website in 2005, and has continued to refresh and enhance their system on a regular basis.

Statewide operation currently include a comprehensive traffic, construction, and winter condition reporting system, and related public 511 phone and web systems.

ITD has progressively opened its 511 system to direct public reporting - an approach that, while still in its infancy, holds enormous potential for harnessing crowd-sourcing to bring a wider range of real-time information to 511 at relatively low cost to the agency.


Indiana Department of Transportation's (INDOT) CARS deployment includes the CARS 4 operator GUI, the Next-Gen CARS-Web site and the Next-Gen CARS-511 phone system and the CARS-CAP plug-in module.

INDOT joined the CARS Consortium in 2007, and continuously updates their service offerings to keep Indianans abreast of traffic and road condition incidents.


Iowa Department of Transportation has been working with Castle Rock continuously since 1997, when we began development of the original CARS system. In 2006, Castle Rock was also selected by Iowa DOT to build the 511/public-facing components of its traveler information system.

The lead state for the CARS Group consortium, Iowa DOT runs one of our largest CARS deployments, with a public 511 system that includes multiple specialized websites (full-featured highway and truckers' pages, streamlined low bandwidth, and mobile optimized), personalized travel alerts, Twitter feeds, citizen reporting, cameras and DMS, and highway advisory radio.

Additional ITS components are also being integrated with CARS under the Iowa Statewide Information Management System (SIMS) project, currently underway. This project expands the existing statewide Iowa CARS system by including crash reports, traffic radio reports, dynamic message signs, ramp gate status, CCTV, and traffic detector data from six metropolitan areas.


The Kentucky Transportation Cabinet (KYTC) was among the first agencies to deploy the original CARS module as a centralized hub for conditions reporting, along with the First-Gen CARS-511 system which served as Kentucky's first state-wide telephone system for travel information.

Castle Rock deployed Kentucky's first 511 service in 2003, but, more recently, has been working on developing and implementing additional site enhancements, like personalized 511 reports and alerting. In recent years, Kentucky has deployed several new CARS modules including CARS-Segment for winter road reporting, and CARS-Alert D, an automated, personalized event notification service, allowing website users to set up alerts for traffic events that occur on pre-saved, frequently-traveled routes.

KYTC's most recent project has been the expansion of their Kentucky State Patrol CAD feeds to cover the entire state, increasing the volume of imported events in their 511 system by more than ten-fold.


Castle Rock first deployed CARS in Louisiana in 2007, and continues to actively enhance the 511 system for the Louisiana Department of Transportation and Development (LADOTD). This statewide system now includes two operator entry modules, the 511 phone system, and three public websites (full-feature, streamlined, and 3G for mobile users).

Recent additions to the Louisiana deployment include the launch of a low-bandwidth, streamlined public website, specifically designed to help handle large spikes in site traffic that can occur when seasonal hurricanes hit.

LADOTD also recently launched a new, multi-modal, data entry module that allows CARS operators to quickly assign operating status reports to ferry routes, which are then disseminated across the 511 system.


The Maine Department of Transportation has used the CARS system since 2001 for reporting roadway incidents and other traffic-related events, statewide. Maine's CARS deployment began as part of a multi-modal region-wide traveler information system (Trio), including a centralized condition reporting system (CARS) and related next-generation 511 phone and next-generation web dissemination system.

Maine's current CARS deployment includes the CARS 4 operator GUI, the Next-Gen CARS-Web site, the Low-bandwidth companion site, and the Next-Gen CARS-511 phone system, as well as the CARS-Routes plug-in module, which allows site users to map and save frequently traveled routes.


Minnesota DOT (MnDOT) has worked under contract with Castle Rock on CARS/511 systems since 1997. We built and deployed Minnesota's first 511 phone service in 2002, creating the initial CARS-511 module to import data automatically from MnDOT's CARS event database. With a fully automated, front-end, interactive voice response 511 phone service, MnDOT had one of the first 511 systems to launch in the U.S.

MnDOT has since upgraded and enhanced its CARS and 511 deployments to inlcude automated data inputs from 5000 traffic detectors, the state police CAD (Computer-Aided Dispatch) system, hundreds of cameras, hand-held field devices amd media exports. Minnesota was also the first state to run a CARS-based Twitter feed (@MnDOTTraffic). In 2010, MnDOT launched Next-Gen CARS-CAD, an automated system that allows crash reports from Minnesota State Patrol to flow into CARS 4.

Most recently, MnDOT spearheaded the development of two new modules; a specialized 511 site specifically for Truckers, and a 511 mobile app, available for iOS and Android devices.

New Hampshire

New Hampshire is part of the "Trio" group of states which also includes Maine and Vermont - a group which was among the earliest members of the CARS Group and, along with Iowa and Idaho, spearheaded the development of CARS 4.

In addition to CARS 4, New Hampshire Department of Transporation uses CARS-Segment for winter-road condition reporting, and a Delcan front-end TMS to import many event types into its statewide CARS database. New Hampshire disseminates traveler information to the public via a Next-Gen 511 phone system and public web site. New Hampshire's Next Gen website displays weather stations and traffic cameras, in addition to links to Smart Work Zone site information.

Most recently, New Hampshire participated in expanding North American FEU Hub development and deployment, development of a Google data feed originating from the Hub, and enhancement of the Delcan to CARS FEU data feed.

New York State Thruway Authority

New York State Thruway Authority (NYSTA) joined the multi-agency CARS group in 2006.

For NYSTA roads, the CARS system acts as both an ATMS (Advanced Traffic Management System) and an ATIS (Advanced Traveler Information System). It provides a central database and GUI that integrates and disseminates roadway event information both for traffic management center operators and for the traveling public.

The New York State Thruway Authority project includes the following requirements; gathering, design, development and operations of a centralized condition reporting system (CARS) and related traffic management tie-ins, including LPFM/HAR, DMS, and travel times.

Rhode Island

The Rhode Island Department of Transportation (RIDOT) operates our CARS 4 module for event entry, and disseminates information to the public through the Third-Gen CARS-Web public site and 511 phone system. The RIDOT TG-Web site allows users to view incident reports, Google traffic speeds, planned events, and images from more than 125 CCTV cameras statewide.

Rhode Island joined the CARS group in 2005. RIDOT's next planned expansion of their system will include imported events from a local data entry interface called RhodeWAYS.

Sacramento Area Council of Governments

In 2008, Castle Rock was awarded the competitively bid STARNET project with the Sacramento Area Council of Governments (SACOG), a voluntary association of local governments comprising six counties and nearly two dozen cities in the Sacramento area.

The project's goal is to enable real-time sharing of traffic, transit, and weather information among a network of local and state government agencies. Sacramento's first 511 service, a regional ITS deployment throughout the city of Sacramento, CA, and its neighboring cities and counties, brings together local governments, transportation agencies, and emergency service providers in a cooperative data-sharing effort across the Sacramento metropolitan area.

In addition to integrating motion video cameras, DMS signs, traffic speed data, California Highway Patrol CAD imports, CalTrans lane closures, trucker and transit information, and personalized 511 reporting, Sacramento also developed a Spanish-language version of their full-feature web site.

In 2012, the STARNET project was expanded to include the San Joaquin Council of Governments (SJCOG), which entered into a partnership with SACOG to share a 511 presence, now known as River Region 511.
