ARCADY 7 New Features

Brand new User Interface

The ARCADY user interface has been completely rewritten to use a similar style as TRANSYT 13 and OSCADY PRO.  The new GUI provides window and file management tools, data grids, undo/redo, task lists and many more.  Data can be entered in any order and easily changed at any time using a variety of data input tools.

Scenarios, Analysis Sets and Demand Sets

ARCADY 7 allows the entry of multiple geometries and flows for different time periods and years in the same file.  A summary results screen shows instant results for all scenarios and allows the user to immediately compare roundabout performance across ALL scenarios.

Model linked roundabouts

ARCADY 7 can model systems of linked roundabouts, making it possible for the first time to model double roundabouts and other more complex systems.   Blocking of internal links between roundabouts is modelled, along with the consequent transfer of queues to entry arms.

Interactive Junction Diagram

Roundabouts can be viewed, edited and manipulated graphically.  Turning counts, flows and other data can be shown graphically for each arm, along with queues, flares and pedestrian crossings.  Various overlay modes are available, including depiction of the relative proportions of entry, exit and circulating traffic, colour-coded by origin or destination.

Choice of units for all data input and output

Choose between vehicles or PCU, per hour, minute or time-segment.  Various units are also available for delays, distances and speeds.  The ability to change units at any time offers maximum flexibility in data entry and reporting.

Performance Analysis

ARCADY 7 includes powerful analysis modes to generate graphs and charts of almost any data.  An optimiser mode finds the best set of parameters to meet any required target performance.  Other tools provide easy ways to quantify variation in performance due to uncertainty in measurements and to determine the additional traffic demand that roundabouts can cope with.

New modelling features

A number of new modelling features have been added, including the ability to model entry and exit restrictions, a Puffin crossing model, minimum/maximum capacity functions, Peak Hour Factor traffic flows.  Slope and intercept values can be entered directly and more options for flow and capacity scaling are now available.  Each arm can use a different traffic profile type and new outputs have been added, including random queues and calculated entry, exit and circulating flows for each arm.

New reporting modes

Customisable reports contain all input and output information, including custom data grids.  Reports can be viewed using the built-in HTML viewer and can be exported as Word or PDF documents.  A powerful Comparison Tool makes it easy to generate reports showing the differences between two or more files.

Other new features

A Glossary Screen is available at all times, showing detailed information about the currently selected data item.  Most screens allow data to be easily transferred to and from other applications, making it easy to quickly transfer traffic flows to/from spreadsheets.  ARCADY 7 includes many more.

ARCADY 7 is compatible with all previous versions. This allows data files created with older versions of ARCADY to be incorporated and analysed by the new program.
