Purpose of Implementing a PMS
• Assist agencies in making decisions about What, Where and When a treatment is needed.
• Analyze the impact of pavement management strategies in pavement future condition and budget needs
• Assist to obtain the best return of allocated funds

Why PMS and GIS as an Integrated System ?
PMS• Information must be
stored in a database• Data is retrieved from
the database according to the user’s needs
• PMS must be able to answer what if questions
GIS• Information in the
database can be stored using location and attribute.
• GIS can show the information visually generating maps that answer what if questions

Budget Analysis• Fund Needs are
determined based on the selected pavement management strategy
• Impact analysis can be done for different funding scenarios
• Results from impact analysis can be shown in Access Reports or using GIS

Benefits of implementing an Integrated GIS-PMS
Funds can be expended more effectively by using an Integrated GIS-PMS in the analysis
Facilitates the communication of budget needs with funding authorities
Provides alternative options for a better justification of the funds requested by showing in theme maps the consequence of an inefficient strategy or insufficient allocation of funds

Recommendation …
Use GIS as Global Tool !!!
Implementation of PMS with other facility systems using GIS as the heart of the central database will allow to share and contrast information more easily.– Avoiding conflicts among projects.– Saving money – Getting the maximum economical and social
benefits from the invested funds
