The document describes Pennsylvania DOT's efforts to develop a mobile application and database to collect data on local roads and bridges. It aimed to address PennDOT's lack of data on local transportation systems. Field collectors used a paperless mobile app to gather attributes of local roads and inventory bridges between 8-20 feet. The project created Pennsylvania's first localized road network database and established procedures for ongoing data collection and management using modern technology. It provided benefits like improved project planning and increased public safety. Lessons learned included defining requirements early and testing devices for field data collection.

Problem Statement
PennDOT cannot produce a holistic view of
its transportation system with internal
data.
Establish a local road network with data
attributes.
Inventory local bridges between 8 & 20 feet.
Utilize modern technology to incorporate
mobile applications.

What do we get in the long run?
Better planning and programming of Local
bridge projects
Established local road network with
attributes
Local outreach
5. www.dot.state.pa.us
Foundation
Establish a platform to work from
Roads
Created geometry for existing local road data
Liquid Fuel Roads
Created geometry for uncollected local data
Non-Liquid Fuel Roads
Bridges
Create potential locations for field collectors to visit
Established criteria requirements for collection
Result – transition to paperless mobile point and
click application

Benefits of this project
Created a completely paperless process
from data collection to data sharing
Brought to light good business practices
and collection methods for field work
Pioneered PennDOT-world of mobile data
collection and asset management
applications

Lessons Learned
Defined Database model before the
creation of Database Tables!!
Establish requirements and desired
application functionality that is very
definitive and clear
Test multiple devices to see what unit is
the best fit for your project needs
RAM, Hard Drive, Screen Size

End Results
Having an inventoried network of roads
and bridges to assist in Linking Planning
and NEPA (National Environmental Policy
Act)
Websites accessible to public to view
assets and assist in managing them
Greatly increase public safety
Local Road Linear Referencing System
(LRS), with attributes
