Learn more about how Choose Best Facilities works
Examples
Example uses for this tool include the following:
- A county library system is undertaking a community outreach program. They use the Allocate to existing facilities goal to assign neighborhoods to their closest library branch and determine how many potential patrons each branch is serving.
- A national grocery store chain has just taken over 18 stores in a county from another chain that went bankrupt last year, leaving the stores sitting empty. They want to set up two new distribution centers to service the stores and have identified seven warehouses that, with some modification, will meet their needs. They want to determine the two warehouses that will minimize the total time the delivery trucks spend on the road each day, which will help reduce costs. They use the Minimize travel goal to find the best location for the distribution center to minimize the overall travel time to deliver to the chain of grocery stores.
- A city is planning to create a park that will serve as a green space for several neighborhoods. They use the Maximize coverage goal to choose the proposed park site with the greatest number of the city's residents within a 5-minute walk.
- It is tornado season and the county emergency management agency has identified school auditoriums that have been used in the past as disaster relief centers. However, in recent years, the capacity of the centers has nearly been exceeded, so this year they think they will need three additional centers. They identified a number of community centers that might be available. Based on square footage, they estimated the number of beds each center could to provide. They want to assign residents to their nearest center, find out how much of the population is covered by the centers, and determine if there are parts of the mainly rural county where the number of beds is not adequate so they can add more centers. They use the Maximize coverage with capacity goal to find the best locations for the disaster relief centers to ensure the greatest number of people are within a half-mile of a center.
- A national pet store chain is moving into a new market—a large suburban county—and has identified a number of empty properties that could be used for the stores. Their goal is to locate the stores so that 40 percent of the county's pet owners are no more than a 10-minute drive from a store. They want to determine how many stores they'll need to open to meet their goal and where the stores should be located. They use the Cover a percentage of demand goal to find the best locations for the pet stores.
Usage notes
The Choose Best Facilities tool includes configurations based on the selected goal: Allocate to existing facilities, Minimize travel, Maximize coverage, Maximize coverage with capacity, or Cover a percentage of demand.
Allocate to existing facilities
The Allocate to existing facilities goal includes configurations for analysis settings, demand locations, facilities, and result layers.
Analysis settings
The Analysis settings group includes the following parameters:
- Travel mode is the travel mode used to determine the distance between facilities and demand locations. Travel modes are configured by your ArcGIS administrator and can be based on travel time or travel distance.
- Departure time specifies the date and time that the traveler departs from the facilities or demand locations. This parameter is available for time-based travel modes such as driving time and trucking time and has an impact on the travel speed. The parameter options are as follows:
- Now—Traffic conditions will be based on the current date and time. Live traffic conditions will be used when available.
- Custom date and time—Traffic conditions will be based on the specified date and time. If the custom date and time is within four hours of the current time, live traffic conditions will be used. If the custom date and time is not within four hours of the current date and time, average historical traffic conditions for the day of week and time of day will be used. Use this option to perform analysis with typical traffic conditions. For example, choose 9:00 a.m. on the previous Monday to perform analysis with typical conditions for Mondays at 9:00 a.m.
- Time unspecified—Travel speeds will be based on average historical speeds or the posted speed limit.
Travel direction specifies the direction of travel that will be used to choose the best facilities. The network may have different one-way restrictions, turn restrictions, and travel times depending on the direction of travel that influence which facilities are chosen. The direction you specify depends on the type of analysis.
The parameter options are as follows:- Facilities to demand locations—Travel begins at facilities and moves outward toward demand locations. For example, from fire stations to houses.
- Demand locations to facilities—Travel begins at demand locations and moves inward toward facilities. For example, from houses to library branches.
