Field Entry Data

The strip map should be made complete by entering field data to show road details in every aspect. The headings on the strip map blank indicate much of the required data. Figure 3-5 through Figure 3-8 show examples of how the data should be presented.
If the roadway is not divided, it is not necessary to repeat the right-of-way and roadbed width, surface width and type, grades over three percent, and curves over two degrees for both directions of travel.
In addition to the headings on the strip map blank, the following information should be shown:
Information to Show on Strip Map
Information Item
Notes
Name and highway number of the route to be zoned
  • Show all names and/or highway numbers if the route has more than one name and/or highway number.
  • Indicate sections to be zoned by Transportation Commission minute order with a wide center line on the strip map.
Crossroads and cross streets
  • Show all names and highway numbers if the crossroads and cross streets have more than one name and carry one or more highway designations.
  • Show numbered highway routes by wider lines than those used for county roads and city streets.
Limits of the speed zone
Indicate reference marker and milepoint and control and section numbers. Reference markers are generally in even two-mile increments, for example: 100, 102, 104. Speed zones or distances will be measured plus or minus from the reference marker.
EXAMPLE: 102+1.343
Adjoining speed zone(s) of connecting map(s)
-
Limits of any incorporated city or town
Show reference marker and milepoint and control and section numbers for these points.
Names and approximate limits of the developed area of unincorporated towns
Indicate by “beginning of developed area” and “end of developed area” under the heading, “Development” — not as “city limits.”
Urban districts
  • Indicate any urban district clearly under the heading “Development.”
  • Urban district is defined in the
    Texas Uniform Act Regulating Traffic on Highways
     as “the territory contiguous to and including any highway or street which is built up with structures devoted to business, industry or dwelling houses, situated at intervals of less than 100 feet for a distance of 0.25 mile or more on either side.”
Schools and school crossings
  • Show only those schools abutting the highway.
  • Show location of schools.
  • Show all school crosswalks.
Traffic signals
Show location of existing devices to aid in proper spacing and placement of speed zone signs.
Important traffic generators
Show all factories, shopping centers/malls, and any other establishments that attract large volumes of traffic.
Ball bank readings
Show each direction of travel for all curves having a safe speed of 10 miles per hour or more below the statewide maximum speed limit.
Railroad crossings
  • Indicate the number of tracks and type of grade crossing protection (crossbucks, cantilevers, crossbucks with signals, gates).
  • Show the name of the railroad at each crossing.
Bridges
Indicate if the roadway on the bridge is narrower than the roadway on either side of it.
