Dyn Seg for Pavement Management

• MTC GIS Users Group Meeting
• February 27, 2003

2
MTCs Pavement Management System (PMS)

• Storage, analysis and reporting software
• Collection of stored pavement data
• Maintenance and treatment costs
• Data and formulas on pavement deterioration
• Calculates future needs budget scenarios
• Software produces text reports
• Pavement Management Technical Assistance Program
  (P-TAP) helps fund the linkage of PMS GIS

Linking GIS and Pavement Management Segments
In an ideal world, there would be a one-to-one
relationship between GIS base-map segments and
pavement segments

Linking GIS and Pavement Management Segments
In reality, pavement segments frequently dont
match GIS base-map segments

Linking GIS and Pavement Management Segments
LRS and dyn seg allow you to model one-to-many
relationships between GIS base-map segments and
pavement segments, without splitting the GIS
base-map
