Emergency Management

Mapping

Some transportation routes are located off-highway but still require emergency planning and response.  Most common are railroads and rail/bicycle trails.  These routes often have address systems that are dissimilar to conventional street or highway addresses.   

  

Examples of Railroad Map Plots:

• Milepost locations (the railroad address system)
• Political/911 jurisdictions by rail line and milepost
• Rail line in relationship to street or highway grid
• Potential access points
• Railroad “place” names – not found on conventional maps
• Infrastructure locations (bridges, tunnels, junctions, interchanges)

 

Examples of Biking/Hiking Trail Map Plots:

• Trail heads and parking locations
• Political or 911 jurisdiction by trail segment
• Milepost or other geographic measurement feature
• Gated access & pubic road crossings – potential access points
• Shelters, water or restroom facilities
• Special geographic features
• Trail location in relationship to road or highway features

 

Examples of Special Event Map Plots (runs, walks or marathons) 

• Staging, start & stop locations
• Line or route of the event plotted on or against street/highway grid
• 911 jurisdictional response areas
• Police or other traffic assistance points 
• First Aid, comfort or official reporting locations
• Event signage, barricades or other physical guides
• Event officials & communication posts

 

 

CTA locates and assigns latitude/longitude addresses to the unique addresses one might find in off highway locations.  This addressing allows planners and responders to quickly locate these locations on their map bases.
