Highway Management Information System -- HMIS
The Maryland State Highway
Administration (MSHA), Highway Information Services Division (HISD) develops
and maintains an annual inventory of all public highways in the State of Maryland.
The inventory includes of a variety of
roadway features, GPS, alignments, and all attributes that are associated with the
roadway centerlines. The HMIS
application, included as a module in the whole Traffic Monitoring application, is a core tool used by
HISD to capture and process the data. EnterInfo developed and maintains the HMIS WEB Site and database for the
The HMIS system was
originally developed using the CASE tool with an Informix database in the
backend. EnterInfo converted the system
to Visual Basic and Oracle and used ESRI ArcIMS and ArcSDE to enable the data
and maps on the Internet.
involved a full Software Development Life Cycle (SDLC).Services provided included strategic
planning, requirements analysis, JAD sessions, database modeling, road data
collection, design documents, user case analysis, GIS data conversion, SHA
software standard compliance, hardware evaluation/benchmarking, systems
integration, WEB programming, and report generation.
HMIS has a
field data collection module, which integrates GIS with GPS and a Distance
Measuring Instrument to automatically create event database records registering
on the mile point of the road centerline.The field data module provides a paperless working environment in the
MSHA field van. It offers the ability to
verify existing data and create new roads with all the required
attributes. While the vehicle is
traveling, the GPS determines the current location and displays all the events
such as a crossroad, bridge, lane change, etc. The map display provides a map
view that can be sized and rotated to align with the driving direction.
Input can be performed using touch screen,
mouse, or keyboard. This project did not
implement the available voice command option.
