Information on the Expert System

The expert system is a web-based series of interactive query pages that allow localities to consider an extensive range of land use and transportation quality growth tools and techniques (over 100 in total, click here to see the entire list) that encompass regulatory, land acquisition, infrastructure investment, market pricing, and planning related techniques to promote specific growth goals. Not all quality growth implementation tools and techniques are appropriate to all settings in Texas, therefore the web based expert system offers various criteria to help localities sort through the implementation tools to identify those that best match their particular context and need. For example, what works in a large or fast growing city may be less appropriate or useful in a slower or smaller city with less planning staff capacity and market demand for land. As another example, a locality may only want to consider well established and tested implementation tools and techniques rather then those that are still viewed as untested or experimental. Thus, in addition to these factors, the tools and techniques can be sorted through based on several other factors such as:

1. Whether the tool represents more of a planning vs. a market vs. regulatory or a capital investment approach to development management or transportation management.
2. The likely costliness to implement a tool or technique
3. The likely lead time to implement a tool or technique
4. The level of congestion on the road network
5. The socio-economic characteristics of the city population and its desired transportation service levels.
6. The planning culture of the community (e.g., a continuum of a free market laissez-faire approach to a strong acceptance of a more planning/regulatory framework)

Lastly, localities can explore implementation choices also based on our expert panel assessment of the effectiveness of the implementation tools and techniques based on the U.S. experience to date.

How to Use the Quality Growth Expert System

As a first step, we highly recommend you create a user log-in so that you can retrieve saved searches at a future date. Once you have logged in, you are ready to use the expert system to explore the tools and techniques that can be used by your community to implement a desired quality growth goal. The first page of the expert system requires you to select a quality growth goal you're interested in implementing in your community (based on the list of 12 goals).

The next two pages of the expert system offer filters to limit the number of implementation tools to only those that best match your local context. The first page lists Local Suitability Characteristics so you can select implementation tools that match the local context of your community (e.g., rate of growth, city size and political culture). Once you have selected any desired local characteristic, click "Next" at the bottom of the screen. The next page lists certain policy characteristics that might best apply to your community's administrative culture, timeframe or openness to innovation.

However, if you wish to maximize the range of implementation tools to implement a given quality growth goal - do not click any Local Suitability or Policy Characteristics and just click "Next" at the bottom of each page. When you click "Next" at the bottom of the Policy Characteristic page, the next screen is your search results. The "Search Results" page is a listing of all the tools and strategies that can be used directly or indirectly to implement your desired quality growth goal. That list can also be re-sorted based on its implementation effectiveness by clicking the "sort by" link at the top of the right hand column.

Each tool listed on the "Search Results" page has a hypertext link to a resource page that briefly describes the implementation tool, offers links to on-line reports and studies where available, and offers brief synopses of the use of the implementation tool in Texas, the US or in some limited cases, abroad.

We envision two possible situations where central Texas communities might find the expert system useful for their ECT implementation purposes. The first is to facilitate the implementation of a new community plan or planning process. In this case, the toolkit basically helps a community to identify the full gamut of implementation choices for a given quality growth goal. The community can use the tool resource page links to find out whether the tool makes sense in their local context.

A second possible application is for a community that is re-visiting the implementation progress of an existing community plan. In this case, the expert system might help a community understand why some implementation tools currently in use are underperforming (e.g., the expert system may show that one or more tools ranked low on effectiveness in our research) as well as offer suggestions for new implementation tools that hold greater promise (e.g., those that ranked higher in effectiveness in the search list).

As a closing comment, it is important to note that the expert panel that helped create and rank these tools overwhelmingly noted that successful implementation of any quality growth goal is most likely to succeed where a system of complementary implementation tools are in place as opposed to a single implementation technique (Paterson et al, 2003). In a separate study by Wilson and Paterson (2003) that reviewed 32 Smart Growth exemplar programs across the US, the authors reported that the most successful Smart Growth communities were those that used multiple complementary implementation tools and techniques to accomplish desired goals and objectives.

We hope you find the expert system of great use in implementing the ECT Vision in your community.
