Castle Rock work in action




Where weather and traffic intersect

Always forward-looking and progressive in all aspects of its transportation operations, MnDOT has worked closely with Castle Rock to ensure that its 511 offerings remain at the forefront of innovation.

Castle Rock built and deployed MnDOT’s first 511 phone (IVR) service in 2002, making Minnesota one of a handful of early adopters of 511 after the FCC designated the number as the official source for travel information in the US.

Since then, MnDOT has spearheaded much of our most ground-breaking work. Recent developments include:

  •  Our first 511 mobile app (iOS and Android)

  •  The 1st integration of snow plow images in both  511 web and mobile app

  • Automated, weather-model driven winter road condition reports

  • Automated roadwork reports driven by GPS signals from roadwork equipment in the field.

  • Real-time safe parking space information, geared toward truckers.



Providing excellence in 511 information, for both the rural and the urban traveler

Travelers in Idaho can get the latest on highway, weather, and road conditions on Idaho 511. Castle Rock's CARS platform and TIaaS offerings are the engine behind it. Web site, mobile app, social media, and phone IVR are available--all with synchronized, consistent, real-time data.   

Idaho has been a major innovator in bringing new, pioneering features to the 511 platform that work for both the rural and the urban traveler.  

Recent key developments include:

  • Advancement of the MODES toolkit to support the development of modern, real-time transit data throughout the state

  • User-friendly RWIS (road weather information station) alerts

  • The fusing of NWS forecast data with ITD's  winter road reports, giving users information both about what the roads look like now, and whether conditions are likely to improve or deteriorate in the next 4-6 hours.

  • 511 citizen reporting, allowing members of the public to submit road condition reports and comment on others' reports.

  • Beautiful onboarding tutorials for the 511 mobile app.



A 511 platform for improving mobility and safety

When winter storms hit Iowa, usage of the 511 platform soars.  People want to know--what do the roads look like? Are any closed? Is now a good time to take my trip? Our clear, consistent designs on web, mobile app, IVR, and social media ensure that people can quickly get information to help answer these questions.

Thanks to the Iowa DOT GIS group's innovative Track-a-Plow development, Iowa's 511 users can see at a glance where all the DOT snow plows currently are, what they are doing, and recent snapshots from the plow's dashcams. NWS weather and winter driving reports from public agency field staff ensure that people know where the storms are; where they are headed; and the current conditions of the roads. Camera and motion video feeds are woven together, giving everyone a visual picture of what the roads look like right now.

Your 511 accounts allow users to sign up to receive text and email alerts, and plan their routes using multiple transportation modes.

We also offer specialized views of the system for Truckers, emphasizing current weight/width/height restrictions, rest areas, and weigh stations.

Iowa is a shining example of an agency using social media to connect meaningfully with its customers. Our automated Twitter/Facebook feeds ensure that the latest road reports go out over social media, while Iowa's 511 team adds a human touch with public safety announcements, special notices, and direct interactions with followers.  



An open-data platform supporting regional coordination and inter-agency partnerships

The STARNET platform in Sacramento runs on Castle Rock's CARS engine. In our Sacramento deployment, CARS enables the real-time sharing of traffic, transit, and weather information among a network of local and state government agencies. Regional incident, weather, traffic, lane closure, and ITS asset status data come together in a common, easy-to-use user interface.  

All STARNET data are centralized and shared through an Open Data Hub platform so they can be leveraged by anyone.  Creative, innovative use of the data by anyone and everyone is encouraged.  

SACOG was also a key agency in supporting the development of our MODES platform. MODES allows any transit agency--regardless of size or current technical level--to quickly and easily develop and maintain GTFS and GTFS-realtime datasets.   Simple, web-based tools allow SACOG's partner transit agencies to hit the ground running and join the Google platform, reaching a much wider audience.



A 511 Transformation Story

In a timescale of less than 6 months, Castle Rock worked with NDOT to carry out a complete revamp of their 511 platform.  Now, travelers in this Great Plains state can get clear, concise, and consistent information about the state of the roads, by phone, web, and a mobile app that talks! This is especially important during winter storms, which frequently cause wide-scale road closures and "white-knuckle driving" conditions throughout the state.



Focusing on GIS, Trucking Permits, and Winter Ops

Behind Indiana's traveler information web site and phone service, you'll find the Castle Rock CARS platform and TIaaS offerings. INDOT's traffic management teams work hard to keep incident, winter driving condition reports,  closures, roadwork, and restriction data information current so that the latest and greatest can be found at or by dialing 511 in Indiana.

In Indiana, CARS is also the system of record for statewide size and weight restrictions, feeding data into Indiana’s oversized/overweight truck permitting system. 

INDOT and Castle Rock recently worked together to establish a data pipeline between its Esri GIS system and CARS. The interface we developed collaboratively ensures that the location information on 511 always reflects the most recent ground-truth from INDOT's GIS team.



511 for hurricanes, floods, and ferries

In the land of hurricanes, tropical storms, and record floods (and even the occasional freak blizzard), the 511 platform is mission-critical. In Louisiana, Castle Rock's CARS and TIaaS platforms import data from the state's Advanced Traffic Management Platform to keep data current on 511. This is especially critical when storms like Katrina and Harvey sweep through the state.  Real-time updates about closures, floods, and road conditions are available via web, app, phone, and social media.

LADOTD also leveraged our platform to allow operators to create real-time ferry status updates for 511, quickly and easily. Click on the ferry icons at or by downloading the Louisiana 511 app (iOS or Android) to find out whether the ferries are currently running!



An ICMS-driven 511 Service

SANDAG selected Castle Rock to leverage our CARS and TIaaS offerings to reinvent the region's 511 phone and web site offerings--and to save big on ongoing M&O (maintenance and operations) costs. All data on San Diego 511 originate with the region's ICMS (Integrated Corridor Management System) platform. No manual data entry is required.   Travelers can dial 5-1-1 in the region for the latest info, or visit

For the New York State Thruway Authority (NYSTA), Castle Rock's CARS platform provides both ATMS (Advanced Traffic Management System) and ATIS (Advanced Traveler Information System) functionality. CARS serves as a central database and TMC Operator Interface for integrating and disseminating roadway event information, both for traffic management center operators and for the general public.  Our Highway Advisory Module allows the Authority's HAR stations to be updated fully automatically using events in the CARS database. Our DMS module provides decision support for managing and coordinating the messages on the Authority's fixed and portable dynamic message signs. Our travel times module calculates and prepares real-time drives times for the radio and for DMS along the Thruway's roadways.



Open Transit Data

Valley Regional Transit leverages the Castle Rock MODES platform to turn its internal operations data into open formats so that it can be leveraged by Google, Idaho's 511 system, and others. The MODES platform transforms VRT's routes, schedules, stops, bus locations, delays, and service alerts data into standardized GTFS and GTFS-realtime feeds.
