House Bill 1353

(75 mph speed limit)

Project Background - Regulatory Requirements

Establish speed limits up to 75

mph:

• TRF conducted speed studies

on high-speed roadways

• Austin District evaluated the list

• Update of speed limit signs and

strip maps was required

3

Project Background – Strip Map

General description of strip map

• A strip map is a document that records speed limits, roadway details, and

requires legislative approval

4

Project Scope:

– Project Location Map

600 Roadway Miles – 11 Counties

5

Project Scope:

– Strip Map

Strip Map Updates included the following:

• Field data collection of roadway details

• horizontal and vertical curves analysis

• Identifying new and existing cross streets, culverts, and other strip map

features

• Ball-banked and calculated curve advisory speeds

• Verify or update all speed related signs

6

Project Scope:

– Sign Inventory System

• Leveraged strip map work to add sign inventory system

• Smart, efficient use of time and budget

Project Scope:

– What is a Sign Inventory System?

• Multi-formatted GIS database

of signage

EXCEL

Google Earth

• Utilizes pull-down menus to

provide information:

Sign Type

Support Type

Anchor System

Sign Condition

Location

Date of Fabrication

MUTCD code

Photos

Evaluate Priority Budget Implement

Replace if:

• Condition

• Plywood

• Bent

• Cracked

• Faded beyond

acceptable

• MUTCD

requirement

• Anchor or

foundation failure

• Age

Plan budget for each

fiscal year

• Learn our needs

& Availability

• Justify the budget

request

Prioritized by:

• Sign Condition

• MUTCD

requirement

• Date of fabrication

Plan:

• Create schedule

• Check inventory

• Order

• Replace

– Summary

Benefits

• Proactive approach to sign maintenance, budget planning,

and creation of work orders

• Complete log and understanding of District-maintained

signs

• Provides comprehensive data of each sign with accurate

location

• Easy to use – Ability to sort and manage signs

• GIS-format – EXCEL and Google Earth

Interesting StatsAnchor Types Percentage

• Triangular Slip Base (72%)

• Wedge Anchor (24%)

• All others (4%)

Challenges and Solutions

Challenge

Safety Field collection

Solution

Proper PPE, daily safety meetings,

hydration, vehicle safety

Data Storage Large data required

for data and photos

Data stored on ArcGIS server (ESRI)

for easy access and redundancy

backup

Organization Unique sign identifier Each sign has a unique ID by using

control section and given sign number

Efficiency Significant data

collection

Consolidate field work for strip map

and signage inventory

Consistency Consistent data

collected and

organized

Use MUTCD sign classifications, drop

down menus, and photos for

verification


19

Challenges and Solutions

ArcGIS Application

• Uses ArcGIS Collector on any computer, smartphone, or tablet

• Inputs and stores information

• Easily access information

• Creates queries and filters data

• Sign points store sign information as well as field photos

of sign face, anchor, and fabrication sticker.

• ArcGIS connects with Excel and Google Earth to create

files readable by anyone


20

Looking Forward

Looking Forward

• Maintenance, storage and ongoing updates to the database

• Training

• Develop sign history

• Proactive sign maintenance

• Budget

• Report labor, equipment, and material with increased accuracy

Sign Inventory System is an Asset Management Tool

• A system that monitors and maintains assets of value

• Helps to determine level of service in the most cost-effective

manner

• Scalable to fit any size or type project


21

Looking Forward

Asset Management Tool can apply to numerous disciplines:

• Bridges

• Culverts

• Illumination

• Signals

• ITS

• Signage

• Rumble Strips/Striping

• Drainage pipes

• Safety End Treatments

• And more…


22

Looking Forward:

– Project Map

Additional 1175 Roadway Miles – 3 Counties – Est. 25,000 signs

Urban – Strip maps older than 5 years

Rural – Strip maps older than 10 years
