MDPW: Analyzing Garbage District Routes and Cart Capacities

On 16, Apr 2013 | In Mapping Solutions, Spatial Analysis | By Erin Olshefski

GIS is intended to be utilized to provide solutions to spatial problems. Vehicle routing is a spatial problem, with garbage routing being a classic example. Recently, the studio undertook the project of assisting Milwaukee Department of Public Works in creating a network dataset to efficiently route their garbage trucks that service over 190,000 households. A project like this requires the consideration and coordination of many variables, most importantly the consideration of time, capacity, and efficiency.

My role was to analyze the current garbage pick-up routes by district, day of pick-up, truck capacity, and cart capacity. My initial findings showed that within each district there was not uniformity in routing by day, causing for inefficiencies in routing- creating the need for trucks to travel on the same streets multiple days of the work week.

Using Excel, I was able to break down the attribute data provided to us by MDPW and find trends. I found that the number of carts picked up per day, the pounds picked up per day, and the pounds per truck per day were not consistent despite the use of the same amount of trucks per day. I was then able to provide a recommendation of carts/day, pounds/day, and trucks/day.

We found that when conducting network analysis and creating a network dataset, it is important to analyze the system already in place to discover existing inefficiencies that should be corrected in order to produce an effective routing solution.

Geo-coding addresses from an Excel sheet in ArcGis 10

On 05, Sep 2012 | In Mapping Solutions, Spatial Analysis | By Nick Lazarides

Geocoding Addresses from an Excel Sheet

 

  • Be sure to format the Excel sheet so that the address is broken up into separate columns.
  • Address (house #, & direction), City, State,and Zip Code

Ex.)

 

 

 

 

 

 

  • Once the addresses are in this format, you can add the sheet to ArcMap the same way you would add any other data.

 

 

 

 

 

 

 

 

 

  • Once you have the sheet in ArcMap, right click on the file and select “geocode addresses”.

 

 

 

 

 

 

 

 

 

  • Select an address locator to use from the list and select “OK”
  • Be sure that your input fields match those in your Excel sheet, and save your output to a proper location.

 

 

 

 

 

 

 

 

 

 

 

  • View the number of matched addresses to see how many were correctly matched.

 

  • Unmatched addresses may be a result of improperly formatting the address in the table, or it may not be recognized as an address by ARC GIS.

How to use the Customer Prospecting Tool for Business Analyst

On 20, Aug 2012 | In Business Intelligence, Mapping Solutions, Spatial Analysis | By Amy Peters

How to use the Customer Prospecting Tool for Business Analyst

 

Customer prospecting allows you to locate regions with ideal demographic characteristics for targeting new customers.  This tool will produce an output layer that will contain demographic data that you define in the Demographic Query dialog box.  This layer will display only the criteria that is meets the requirements you set.  For example, a new company could use this tool to help show them where their target market is located after they figure out their typical consumers.

1) Load a Business Analyst ArcMap session.  Under the Business Analyst Desktop Message Center, click on the link that says business analyst.mxd under recent map documents.  This mxd file will show up with all the geographies that you need (zip codes, county areas, state areas, etc.)

 

2) Click the Business Analyst drop down menu and select analysis

 

3) Click “create new analysis”

 

4) Click “market analysis”

 

5)Click “Customer Prospecting”

 

6) Choose a geography that you wanted your information displayed at (zip codes, county areas, state areas, etc.) Then click next.

 

7) Choose whether you want the information displayed at your current extent or if you want it to be displayed based on a layer. Then click next.

 

8) Choose whether you want to used a customer layer with the demographic information already in it or if you want to choose your demographics manually.  Then click next.

9) If you chose the customer layer, choose the demographics you want shown on the map.  If you chose the manual option, double click on a demographic you want and determine the floor and ceiling numbers.  Also if you choose manual you need to decide whether you want to match all of that criteria, any of the criteria, or you can create a custom query.  Then click next.

10) Here you need to name the analysis layer and then click finish.

How to Display Business Points Using NAICS Codes With Business Analyst Desktop

On 17, Aug 2012 | In Mapping Solutions, Spatial Analysis, Tips and Tricks | By Amy Peters

How to Display Business Points using NAICS codes with Business Analyst Desktop

 

The NAICS code, North American Industry Classification System, “is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy” (US Census Bureau).  This data is accurate but somewhat incomplete due to changes that are not captured after the initial NACIS code is assigned. One issue is that if a business changes or adds on additional services, often they do not change or add to their original NAICS code classification. This means they would not show up under our search but it doesn’t mean they don’t exist.

 

1)      Make sure your preferences are set up to save in the correct folder. (see training document called How to set up your preferences to save your files in Business Analyst in the U drive under the training folder)

 

2)      Under  the business analyst drop down menu select ADD BUSINESS LISTINGS
