Scattergrams for Transit Lines and Segments

Following the development of the new Network Calculator, which includes transit line and transit segment computations, module 2.43 "Plot Network Scattergrams" was also enhanced. Besides the already available node and link scattergrams, it includes now also the possibilities to generate and manipulate transit line and transit segment scattergrams. These new types of scattergrams offer the same options and features that we are used to from the node and link scattergrams:

• Unrestricted choice for the variables on X and Y axis, including access to all "inherited" attributes, and the use of the alternate types of addressing, such as accessing j-node, reverse link, vehicle and next segment attributes.
• Interactive query and marking of elements, either by clicking on single elements or by use of the powerful polygon inclusion/&exclusion feature.
• Computation and display of a linear regression of the selected data.
• Optional color, symbol and size index variables allow precise control of the visual appearance of each data point.

In the following example, the Network Calculator was used to compute the variables US1, US2 and US3 in such a way that the resulting scattergram displays load profiles of a set of transit lines.

For more details on the use of scattergrams refer to section IV-2.43 of the User's Manual.
