Sugar Network Editor (SNE) is an add-on to ESRI®’s ArcGIS geographic information system. SNE extends ArcGIS to create and maintain transportation networks:

• Street networks including intersection characteristics and traffic control devices
• Public transit networks including routes, schedules, stops
• Rail networks including routes, schedules, stops
• Trucking networks including routes, schedules, stops
• Other modes such as air and ferry, and service networks such as school bus, postal routes, snow removal, garbage collection and maintenance.

Sugar Network Editor is the ideal tool for users of ArcGIS that need to create and maintain any type of transportation network. These networks are directly compatible with ESRI’s Network Analyst extension and other ESRI extensions, and speciality software products such as Citilabs Cube and Trafficware® Synchro.

True Transportation Networks Networks can be created from scratch or created using existing data from a variety of formats including geodatabases, shape files and several specialty formats. These networks are stored in a geodatabase using a custom transportation data model. The data model allows users to maintain all aspects of transportation networks such as oneway-twoway rules, lane configurations, intersection attributes and geometry, public transit, rail, truck and other mode routes and schedules . Relationships between the networks are automatically managed by SNE enabling true multimodal networks. For example, if a user removes a section of a roadway where buses travel, they are prompted to ask how to resolve the impact on the bus line: re-route the bus line or to create an exclusive bus-way. Docking Windows SNE has three windows: Data manager: imports, exports and manages the networks Feature explorer: provides a convenient way to view and edit the attributes of the network and associated services. For example it allows the user to see and edit the attributes of both directions of a two-way street at the same time. It also allows the user to code and edit services such as school bus routes. Junction editor: brings the ability to fully describe the details of intersections such as type of traffic control, lane configuration of each intersection approach, signal phasing data, movement characteristic.

Tools

SNE has tool bars for creating and editing streets and routes and services. Functions include:

• Add, delete and move roadway segments
• Edit the geometric details of the network such as connectivity and curvature
• Split and reverse the directionality of road way segments
• Automatically create intersections as a new roadway segment is added across existing segments
• Add, delete and move intersections
• Add, delete, re-route, extend, truncate routes and services

Typical Users

Transportation Planners and Engineers, GIS/Network Analyst Users, Routing/Logistics/Supply chain Specialists.

Key Capabilities

• Provides a transportation geodatabase that directly supports Cube and ESRI users
• Provides tools for easy translation (import/export) of your existing Cube models to the ESRI compatible geodatabases.
• Delivers a complete Geodatabase Manager making it easy to create and manage the transportation GIS and network data elements (i.e. links, nodes, and their respective attribute tables).
• Smart/automatic topology management and validation allows users to quickly make edits without breaking or violating the network topology rules.
• Intuitive management of the line directionality and attributes.
• A complete intersection data model and junction editor for management of lane configurations and signal timing at intersections.
• A transit editor for coding rapid transit lines and bus routes.
• On-the-fly creation of ESRI’s Network Dataset format for route logistics and supply chain modeling.
• Facilitates management of complex transportation data elements/features like turn move ments, transit line and stops, and pedestrian and bike linkages.

Key Components/Features when Combined with ESRI’s Network Analyst Extension

• SNE readily builds ESRI’s Network Dataset format required for the Network Analyst exten sion.
• The Network Analyst extension allows you to ‘solve’ different network problems: - The ‘Route’ solver finds the shortest route between a set of user defined ‘stops’ and route ‘barriers’.
  • The ‘Route’ solver finds the shortest route between a set of user defined ‘stops’ and route ‘barriers’.
  • The Service Area solver calculates a service area based on the location of user defined ‘facility’ locations and route ‘barriers’. A good application for establishing service area districts for things like police/fire stations, utility service districts, or retail outlets.
  • The Closest Facility solver routes the closest ‘facility’ based on user defined ‘incidents’, ‘facilities’, and ‘barriers’. This graphic shows an incident in the middle of town, and the resulting closest facility route.
  • The OD Cost Matrix Solver calculate a OD Matrix based on user defined ‘origins’, ‘destinations’, and ‘barriers’.
