4.1.6 Legacy System Interfaces

The CHART II system will allow for the majority of the CHART and Emergency Operations Center (EOC) functions to be incorporated into a single user interface. The CHART II system will provide an NTCIP interface to all legacy systems listed below by means of a protocol converter:

4.1.6.1 WSI, Inc. Weather for Windows/Weather Workstation

The CHART II system will allow operators to view National Weather Service (NWS) forecasts/warning statements, local and national radar imagery, satellite imagery, and other graphic weather maps by clicking on an icon on the display map representing Weather for Windows. Operators will be notified at their workstations of weather based alarms through a pop-up dialog window with a flashing indicator and an audio signal when predetermined thresholds have been reached. Specific sounds and colors predetermined by users and can be used to help operators pinpoint problem areas. All administration and control functions shall remain on the WSI workstation.

4.1.6.2 SSI SCAN Software for Windows

The ability to monitor roadway pavement conditions aids system operators in identifying which roads have ice, thus allowing operators to determine precisely when to deploy salt trucks to treat the roadways. Currently, CHART system operators use a separate system to view pavement sensor data collected by the SSI SCAN system. The CHART II system will interface with the SSI SCAN system to allow operators to view traffic and pavement conditions from a single workstation. System operators will be able to view pavement temperatures by clicking on an icon on the display map. The data will be obtained over pre-determined time intervals, and will be in the same format as the predefined information on the existing SSI SCAN system (e.g., green = dry, blue = some moisture, yellow = chemically wet or snow and ice watch, red = snow and ice warning and black = old data). System operators will also be able to modify these colors without requiring recompilation or reloading of the system.

When predetermined thresholds have been reached, the CHART II system will notify operators at their workstations of pavement based alarms through a pop-up dialog window with a flashing indicator and audio signal. Field personnel will be notified via pagers. Specific sounds and colors predetermined by users can be used to help operators pinpoint problem areas. All SCAN related administrative functions shall remain on the SCAN Server.

4.1.6.3 EIS Inc. Emergency Operations Reporting System (EORS)

Providing operators with the ability to visually monitor roadwork/road closures from their workstation will aid them in recommending alternate routes during incidents. The CHART II system will interface with the EORS to report and track all information regarding resources, personnel (e.g., the MDSHA Data Encyclopedia) and road conditions during emergency operations. The system will show a roadwork/road closure icon on the display map generated from the EORS. System operators will be able to determine the location and status of roadway work and/or closure by clicking on an icon on the display map.

4.1.6.4 Econolite Traffic Signal Software

The CHART II system will interface with the Econolite closed loop systems to provide operators with the ability to implement pre-set traffic signal timing plans from their workstations to support the implementation of a Freeway Incident Traffic Management (FITM) plan. CHART II system operators will only need to activate and deactivate the established pre-set timing plans. System operators will, however, be able to monitor signal system status information by clicking on an icon representing a signalized intersection on the display map. The data that will be available to the system operator for monitoring purposes includes:

The CHART II system will automatically notify the signal shop technician currently on duty in the event a system operator implements a timing plan to support a FITM. Signal shop technicians will still have the ability to adjust traffic signal timing parameters of a timing plan implemented by a CHART system operator.

4.1.6.5 Silverlake Software Airsource Pro Paging Software

The CHART II system will interface with the Silverlake Software Airsource Pro Paging Software that is used to inform and direct both internal and external personnel regarding incidents through the use of alphanumeric pagers. This system is used to inform approximately sixty people each time an incident is confirmed or conditions have changed. The CHART II system will provide system operators with the ability to page these personnel, as well as selected individual personnel, from their workstations. The system will have a menu item that allows operators to select notification resources. The groups to be paged will automatically be determined by the geographic location of the incident. The message text to be sent will automatically be taken from the incident report.

4.1.6.6 Novell Groupwise E-mail

The CHART II system will interface with the Novell Groupwise E-mail software to provide system operators with the same e-mail capabilities as other MDSHA personnel. System operators will have e-mail capabilities from their workstations.

4.1.6.7 I-95 Corridor Coalition Information Exchange Network (IEN)

The CHART II system will interface with the I-95 Corridor Coalition IEN software that provides incident information from Maine to Virginia along the I-95 corridor. The system will allow operators to send submitted incident reports to the IEN through the CHART II Incident Handler Software. The CHART II system will also notify operators at their workstations of incoming IEN alarms through the alarm ticker and graphical map display. Operators will be able to view information from the IEN system by clicking on an icon or an incident acknowledgement window. Via either option, operators will be able to obtain information from the IEN system from their workstations, including:

4.1.6.8 Partners in Motion Independent Service Provider

The CHART II system will interface with the Partners in Motion consortium to obtain and share information in the Washington D.C. area. The CHART II system will allow operators to send submitted incident reports to the Partners in Motion through the Incident Handler Software. Incidents identified from the Partners in Motion will be graphically located on the display map and system operators will be able to click on an icon representing incidents to view a textual description of the problem.
