Question 3: What RCRS is your agency using?
Question 4: Duration of RCRS Use

Question 4: How long has your agency operated a RCRS?
Question 5: RCRS Changes
Survey contributors were asked if they have made any significant changes to their RCRS since it initially launched.
Twenty-one (21) responses were received to this question. Half of the respondents indicated that they have deployed a second generation RCRS and have used the same developer for both versions. Approximately one-fourth of the responders indicated that they switched to a new vendor and/or software systems since their initial RCRS launch. One (1) state respondent (West Virginia) indicated that their RCRS is a first generation system. Overall comments received indicate that changes are needed to continually evolve and improve RCRS. Specific comments received on the history of RCRS in some states included:
- Pennsylvania DOT, which uses an in-house RCRS, implements 3 to 4 enhancements per calendar year to their system. Maryland has been adding 2 to 3 major releases to their RCRS each year since 2006.
- Oregon DOT’s new RCRS version is integrated with their dispatch/incident management system. This new system avoids duplicate entry into both systems.
- The Vermont Agency of Transportation initially deployed CARS for their RCRS. In 2012 an in-house system was developed by Vermont while working with New England states on a new regional RCRS.
Question 5: Have you made any signifcant changes to your RCRS since you intially launched it?
Question 6: RCRS Data Received
Survey contributors were asked what data is received by their agency’s RCRS.
Respondents in over nineteen states indicated that construction activities, roadway or lane blocking incidents, and road weather observations were received by their agency’s RCRS. Ten respondents indicated that their RCRS received travel time information.

Question 7: RCRS Data Entry
Survey contributors were asked how data received by RCRS is entered (manual, semi-automated or fully automated).
Respondents indicated that travel times received by RCRS are fully-automated. Respondents noted that construction activity data received by RCRS are manually entered and semi-automated. Respondents indicated that roadway or lane blocking incidents and roadway weather observations data is received by RCRS by manual data entry, semi-automated systems, and fully-automated systems. A summary is provided in the table below.
Respondents noted that CCTV, DMS, traffic speeds, radar and wind speeds are an automated entry into some agencies RCRS. Manual entries noted by respondents for some RCRS included chain requirements, special events, truck restrictions and maintenance activities.

Question 8: RCRS Data Frequency
Survey contributors were asked how frequently the data is received by their RCRS.
In order to understand each respondent’s ability to meet the SAFETEA-LU Section 1201 Real-Time System Management Information Program (RTSMIP) requirements, the survey asked responders to indicate the frequency at which different data types are updated in the RCRS. The following table describes the Section 1201 requirements.

Question 9: RCRS Data Sources
Survey contributors were asked to identify what sources of data are used for their RCRS.
Respondents were asked if their RCRS data was received from the agency’s network, other agencies, the private sector or travelers. Most responded that data is received from the agency network and only a few identified travelers as a data source for construction, incidents and roadway weather conditions.
Question 9: From what source does your RCRS receive data?
