Introduction
3

• ArcView Network Analyst provides an intuitive,
  interactive, easy-to-use, stand-alone interface
  for calculating travel routes, finding the
  closest facility, reporting the results as
  directions and finding service areas.

4
ArcView Network Analyst solves problems
associated with any network. Users can

• Access geographic network data based on ARC/INFO
  coverages, ESRI shapefiles,or computer-aided
  design (CAD) drawings.
• Find the most direct route between two locations,
  or find the best way to visit several locations.

5
CONTD

• Find the nearest facility
• Perform drive-time analyses.

6
Gives You the Power to Solve Your Network
Analysis Problems

• It enables you to solve a variety of problems
  based on
• Geographic networks (i.e., streets, highways,
  rivers, pipelines, utility lines)
• Finds the most efficient travel route across
  town,
• Generate travel directions,
• Finds the closest emergency vehicle or service
  facility to an incident,
• or Defining service areas or sales territories
  based on travel time.

7
Designed for Power

• True 32-bit architecture.
• Multiplatform portable design (Windows NT and
  95 and UNIX).
• No limits to size of the network problem.
• Networks are persistent with the data, reducing
  solve time

8
Scope of the Project
9
Network Analyst can do the following

• Find the Best Routes
• Locate the Closest Facilities
• Build Service Areas
• Give Clear Directions

10
Answer Your Questions Based on Different Criteria

• ArcView Network Analyst can use any cost field
  for its calculations. You can solve your
  questions based
• on drive time,
• street length,
• traffic conditions, or
• any of a number of criteria.

11
Methodology
12
Find the Shortest Path

• Enter your "stops" using their addresses or by
  pointing.
• Reorder the "stops" automatically to find the
  best order.
• Return to your starting location for a round-trip
  route.
• Solve based on distance, time, or other
  variables.

13
Determine the Closest Facility

• Determine the closest facility(s) from any given
  point.
• Enter your "stops" using their addresses or by
  pointing.
• Change the travel direction.
• Solve based on distance, time, or other
  variables.

14
Generate Service Areas

• Evaluate multiple service centers.
• Set multiple service areas based on time,
  distance, or other variables.
• Change the service areas based on travel
  direction.
• Enter your service center using their addresses
  or by pointing.
• Generate results as polygons and/or lines.

15
Give Clear Directions

• Specify which attributes to form directions from.
• Use existing landmark information within the
  directions.
• Save directions to an ASCII file.
• Set the measurement units to use in the
  directions.

16
Analysis
17
Finding Shortest Route

• Imagine youre the operations manager for a
  moving company in San Francisco and have been
  radioed by one of your drivers. The driver,
  caught in rush hour traffic while in the middle
  of an important delivery, is uncertain of the
  best way to reach his destination. He wants you
  to tell him the shortest way to get there.

18
To give directions to the truck driver

• Specify where the driver is in the city by using
  your cursor.
• Specify where the driver wants to go by entering
  an address.
• Find the shortest route from one location to
  another.
• Generate directions you can read to the driver.

19
Finding the Closest Facility

• You are an emergency dispatcher and get an urgent
  call about an automobile accident at Lombard in
  San Franciscos north side. It is your job to
  decide which ambulance will respond and the
  quickest route it will take to get there.

20
To decide..

• Specify where the hospitals are by using a point
  theme
• Specify where the accident is by entering an
  address
• Specify drive times for city streets by choosing
  a field in the line theme feature table
• Find which hospital is closest
• Find the quickest route from the hospital to the
  accident scene

21
Determine Access Sites

• You are a commercial real estate consultant
  working for a retail company. Your boss just
  asked you to report on how accessible a potential
  retail site is, in a meeting that starts in 10
  minutes.

22
find how many customers live in each area..

• Specify where the site is by entering an address
• Create 5 and 10 minutes drive time service areas
  around the site
• Find out how many customers are located within
  the service areas

23
Generate travel directions

• You are the owner of a small package delivery
  company. You notice there are an unusual large
  number of packages that need to be delivered, so
  you want to assign a driver to start delivering.

24
To create a delivery plan

• Specify where your delivery truck depot is by
  entering an address
• Use a customer theme to specify delivery
  locations.
• Find the most efficient order to deliver the
  packages.
• Find the shortest route to deliver the packages.
