Visualization of the Konstanz bus transportation system

busvis's Issues

Draw concentric rings

Draw concentric rings to visualize the travel time

Alternative to Spring embedder

Position nodes based on original position and radius

When already walking, walking again should not be allowed

The current walking restriction can be tricked by walking again from another bus station.
At 0:00h from 'Spanierstraße' to 'Klinikum Konstanz' and a maximal walking time of 10min
the routing algorithm returns the following path:

Spanierstraße -> Zähringerplatz (walking, 10min)
Zähringerplatz -> Klinikum Konstanz (walking, 9min)

which contradicts the restriction to 10min walking

Live View Broken

The now view can't be chosen any more, it runs into an infinite loop:

at infovis.ctrl.Controller.setTime(Controller.java:282)
at infovis.ctrl.Controller.setFastForwardMode(Controller.java:467)
at infovis.ctrl.Controller.setTime(Controller.java:282)
at infovis.ctrl.Controller.setFastForwardMode(Controller.java:467)
at infovis.ctrl.Controller.setTime(Controller.java:282)
at infovis.ctrl.Controller.setFastForwardMode(Controller.java:467)

Seems to to introduced by #52.

Build an alternative edge oriented positioner

A positioner that represents the length of edges correctly while ignoring the total distance to the start node

More prominent clock

The clock should be more prominent especially in the case of fast forwarding (sliders are greyed-out and the "label-clock" is very small).

Avoid Node Drift

After the focus changed several times, the nodes drift away from their default position. This leads to central stations like Sternenplatz ending up on the edge of the graph.

JVM crashing when selecting previously not reachable node

When a non reachable node is selected the JVM crashes.

Bug when zooming and translating simultaneously

When starting to drag, then zoom, and the translate the viewport jumps to an undefined location. This happens in the main visualization and the overview.

Sometimes the GUI is Layouted Incorrectly

Maybe this can be solved by using another Layout.

Clean up code

Cleaning up code and renaming / refactoring some classes. May brake changes of others, so make sure you commit your current changes now and work with the after milestone version tomorrow.

also:
fixes #25

Secondary selection is erased when changing layouts

Move secondary selection in controller

Better GUI components

The GUI elements that are used for choosing the time are not very intuitive. Changing them to more "common" elements.

Improved Fast Forward GUI elements

Improve fast forward gui elements, adding spinner to the slider and labels. (#28)

Better Routing Algorithm

The routing algorithm is broken and should be fixed. From #14:

Because only one "shortest" path to each station is considered, quicker routes that avoid line changes aren't always taken:

   , 00:00 ---1--- 00:01.
  /                      \
(A) 00:01 ---2---> 00:02 (B) 00:02 ---2---> 00:03 (C)
                           \                      /
                            ` 00:03 ---3--- 00:04´

The optimal route (when change time is greater than zero) would be Line 2, but because (B) is reached quicker by Line 1, it is taken instead.

Labels should avoid each other

Labels should avoid each other while having a connection to the original node.

Priority Queue in Routing

Use a priority queue in the routing algorithm to get early results.

Hour spinner for walk should be able to set min and max time

When changing the hour of max walk it should be possible to generate min/max walking times (0:00h and 1:59h) when minutes are not already correctly set.

Non static BusStations

Get rid of static access to bus stations

Highlight edges from routes

Highlight the edge that are used to get to a station.

Walking Distance in Routing

The routing algorithm should also use the walking distance between stations, e.g. from the Google Directions API.

Selecting multiple secondaries

Secondary selection toggles selection instead of erasing old selection

Timer

Timer does not terminate correctly. May lead to the application not terminating correctly either.

Secondary selection in overview

Being able to select with the right mouse button in the overview. And show the secondary selection.

Try to deploy as android app

Maybe drop batik and as much libraries as possible for that and reduce the size to an android size.

Always show final travel time in secondary selection

.

Show selected route

Show the selected route with additional information. (continues #17)

Bus lines should be identifyable

Maybe with labels when hovering them, showing their names.

Remove overlapping in edge based layout

Remove the node overlaps in the edge based layout somehow.

Animate nodes

Animate nodes in the circular embedder

Controller

A controller class to control the different visualizations.

Edges

Draw edges

Start Time and Change Time do not change immediately

When selecting other values in the control panel the bus station has to be reselected first to actually start the changes.

Node position incorrect

Node positions are incorrect after a few stations were selected.

Draw edges starting from the center

Draw edge from the center, such that highlighted lines are centered.

Exporting jar with Maven

Exporting a jar with maven and adjusting resource loading to handle in jar resources

Remove legacy code

Remove all unused classes (like EmbedderTest, SpringEmbedder or Test) or provide a way to use its functionality.

GUI

Make a feasible gui with sliders etc

Batik throws random uncaught exceptions

Batik throws random exceptions that get not caught and are print to std-err. The application still works fine.

Fast-Forward Animation

It should be possible to increase the speed of the current real-time mode, e.g. to one minute per second.

Data description

Describe how csv files should contain the necessary data for bus plans to give the possibility to add alternatives to the Konstanz bus system.

Loops in routing

On full BusStationManager::maxTimeHours(24) and with the csv data there are loops in the routes found by BusStation::routeTo

Schematic Plan

Visualize the schematic plan

Refine edge based layout over time

Keep the layouting object alive and iterate in the background to refined the layout.

Overview window has wrong size

After resizing the overview window takes as much space as its get which looks odd.

Refine Time Granularity to Seconds

Makes for smoother animation.

Show more labels when zooming in

When the zooming is greater than one begin to show more labels. (BusvisDrawer#drawLabel(Graphics2D, Context, LayoutNode, boolean, String) )

Avoid clutter from nodes

Adjust the angle of a node towards the reference such that clutter from the nodes is reduced.

Remove max wait from GUI
