Background (1/2)Background (1/2)

The Right-of-Way appraisal process often utilizes manual data entry and manual appraisal report generation; an electronic system capable of reducing the likelihood of inconsistent appraisal data and automating the Right-of-Way appraisal report generation process is desired.

Background (2/2)Background (2/2) Individuals with varying degrees of

experience, knowledge and background are employed to perform land appraisals for Right-of-Way acquisition; this may result in variations in the value placed on land between two different appraisers evaluating the same or similar piece of property. A statistical process would help reduce such inconsistencies.

Research ObjectivesResearch Objectives To develop the conceptual framework,

user functional needs, data and technical requirements for an electronic appraisal system (EAS) that can be used to capture, transmit, store, manage, analyze, and report appraisal data to improve the appraisal process and therefore reduce inconsistencies in land appraisal values.

To develop a prototype EAS to demonstrate the key functionalities.

Guiding Principle for EAS Guiding Principle for EAS

“Automate the processes without compromising the quality and quantity of information; serve as a decision-support system rather than a decision-making tool. ”

Electronic Electronic Appraisal Appraisal

System (EAS)System (EAS)

User Functional Needs (1/2)User Functional Needs (1/2)

User requirements are numerous and may vary from state to state.

First step in determining the user requirements of the Electronic Appraisal System is to outline all potential requirements.

This requires defining categories of requirements for the different aspects of the system.

User Functional Needs (2/2)User Functional Needs (2/2)

The user functional needs for the EAS were developed and detailed needs have been outlined for each of the following:

Future WorkFuture Work The following documents have been sent to

participating state DOTs for ranking and comments:

Conceptual Framework User Functional Needs Data Requirements

Comments and rankings will be summarized and these documents will be finalized.

Work will begin on designing and developing the prototype Electronic Appraisal System.

Anticipated ProductsAnticipated Products

A Conceptual Framework to define the EAS A list of User Functional Needs ranked by the

participating DOTs A list of EAS System Requirements to

analyze alternative means for implementing the User Functional Needs

A list of Generic Data Requirements ranked by the participating DOTs

A Prototype EAS to demonstrate key functionalities of EAS

The Bottom LineThe Bottom Line

Essential information required for developing and implementing an Electronic Appraisal System will be available at the end of this study.

The EAS prototype will provide the basis for a future production-level system that could ultimately streamline the right-of-way acquisition process by providing vital information to decision makers at state DOTs.
