Transcription

1 2013 Esri International User Conference July 8 12, 2013 San Diego, California Technical Workshop Network Analyst: An Introduction Patrick Stevens Robert Garrity Esri UC2013. Technical Workshop.

2 Introduction to Network Analyst The basics and benefits of Network Analyst Data: How can I model streets realistically? Solvers: What types of analysis can be done? Network Analyst at the User s Conference

3 Closest Facility Service Area Route ArcGIS Network Analyst Extension Solving transportation problems Origin-Destination Cost Matrix Traffic Location-Allocation Vehicle Routing Problem

4 Benefits of Network Analyst Quickly and easily solve transportation problems Save your organization money Efficient routes means less gas, less maintenance, less driver overtime, more customers serviced Find the optimal locations for facilities or remove redundant facilities Used across ArcGIS: - Across products - Across skill levels - Across data availability Use an accurate model of a transportation network

5 The shortest path Straight-line distance Fastest time Shortest distance

6 ArcGIS.com Map Viewer Requires no local data Routing, directions, service areas

7 ArcGIS.com Network Services Requires no local data Does point-to-point routing, closest facility, service areas, fleet routing, traffic, geocoding Works across all Esri APIs

8 Mobile Routing, directions, closest facility, and service area available for all APIs - Windows Phone - ios - Android Connected available now Disconnected available soon

9 Demo ArcGIS.com Map Viewer & Network Services Esri UC2013. Technical Workshop.

10 Network Analyst controls in ArcMap Network Analyst Toolbar Network Analyst Window Geoprocessing Tools

11 Specialized layers A Network Layer holds a reference to a network dataset.

12 Specialized layers A Network Analysis Layer is a composite layer configured for a specific solver.

13 Demo Network Analyst in ArcMap Esri UC2013. Technical Workshop.

14 Modeling travel on street networks Esri UC2013. Technical Workshop.

15 Street data considerations Cost Quality Scope Expertise required for creation and maintenance - Editing - Database Updates

16 Where do you get street data? Data within your organization No street data in your organization - Free data - Data and maps media - TIGER (Census data) - OpenStreetMap - OSM to NDS tools - ArcGIS Editor for OpenStreetMap - Pay for data - NAVTEQ or TomTom - Vendor street data processing tools - StreetMap Premium for ArcGIS - Pay for analysis - ArcGIS.com Map Viewer - ArcGIS.com Network Services

17 Streets are connected

18 Restrictions Restrictions can depend on: - Street characteristics ONE WAY - Vehicle characteristics 12-6

19 Traffic

20 Intersections You can add a cost to a specific turn 5 Seconds 15 Seconds B Total Time: Seconds 5 Seconds A You can also add a generic cost to every turn in the network.

21 3D Model travel in 3D for: - Buildings and mines - Overpasses - Considering slope 8%

22 Types of travel Travel by: - Vehicle - Pedestrian - Rail - Bicycle - Transit

23 Demo Modeling realistic street networks Esri UC2013. Technical Workshop.

24 Restrict U-turns if You prefer not to make them It s difficult to make them with the vehicle you re driving

25 Barriers for temporary restrictions or slowdowns Natural disasters Severe weather Territory boundaries Construction Road closures

26 Arrive and depart from the correct side of the road

27 Demo Modeling travel realistically Esri UC2013. Technical Workshop.

28 Network Dataset Demo: Takeaways Network datasets model transportation networks Modeling capabilities allow you to create an accurate transportation model considering: - Vehicle qualities - Road features - Traffic A good model leads to good analysis results

29 Route Closest Facility Service Area Network analysis Location-Allocation Vehicle Routing Problem Origin-Destination Cost Matrix Esri UC2013. Technical Workshop.

30 Route solver Point-to-point routing Find the best route for visiting a series of stops with minimum cost You can also - Specify time windows on stops - Find best sequence of stops - Analyze for different times of the day

31 Closest facility solver Find the nearest facilities from each incident You can also - Limit the search distance - Limit the number of facilities to find - Travel from the facility to the incident

32 Demo Dispatching Find the nearest emergency vehicle to an incident Esri UC2013. Technical Workshop.

33 Demo: Dispatching takeaways Use the Closest Facility solver to route groups of vehicles to a location. Network Analyst can easily be used as a web service. All Network Analyst capabilities are available via ArcGIS Server.

34 Service area solver Find the area you can reach from a facility You can also - Solve for many facilities - Use multiple break values - Specify the direction of travel - Output lines or polygons - Analyze for different times of the day

35 Location-Allocation solver Determine the best location for a facility, based on demand conditions You can also - Choose from many different analysis types - Limit the capacity of facilities - Analyze for different times of the day

36 Demo Fire coverage Esri UC2013. Technical Workshop.

37 Demo: Fire Coverage - takeaways Determine your problem type, and pick the most appropriate solver. The Service Area solver provides a tool that shows street coverage areas that are easily visualized. When the problem type is locating facilities, Location-Allocation is the most appropriate solver.

38 Origin-destination cost matrix solver Generate a matrix of the travel costs from origins to destinations You can also - Limit the search distance - Limit the number of destinations to find - Analyze different times of day Origins - Warehouses Destinations - Stores A B C

39 Vehicle routing problem (VRP) solver Route a fleet of vehicles to service a set of orders You can also specify - Vehicle capacities - Driver specialties - Work breaks - Time windows on orders

40 Demo Appliance Delivery Create optimal routes for multiple vehicles to deliver appliances to many customers Esri UC2013. Technical Workshop.

41 Demo: Appliance Delivery - takeaways Route a fleet of vehicles using the vehicle routing problem solver Time windows, capacities, breaks, and other constraints make it a flexible modeling tool

42 Common Questions How do I analyze my utility or natural resource networks? Does Network Analyst support Arc routing (highdensity routing)? Can I get alternate shortest paths? Can Network Analyst work with transit schedules?

43 What s new in Network Analyst Online Services ArcGIS.com Map Viewer Offline routing 64bit GP
