the interface of traffic simulation system

中文版

The interface is about to have 3 regions: the traffic flow visualizer , the manipulation buttons , the parameter setting . For now (2025.03.22), the interface is partially developed as the following image

0 update log ⚙

🏆2025.03.22 | the first update | interface initial push with start button, pause / restart button, visualization regeion and frame slider

update details🚀:

1. The start button can start the traffic simulation with the example data in Example_Data.mat.
2. The pause / restart button can pause the whole simulation in any time when it is pushed for the first time. When it is staying at the paused mode, push it could be restarted by push it again exactly at its pause point.
3. The visualizer region is able to visualize the simulation process with the provided traffic data.
4. The frame slider is a marker of the simulation frames updated for now. It can dynamically update its limitations and sticks when the simulation goes on.

🏆2025.04.05 | the 2nd update | add the back play function to the pause / resume button; add the clean_app.mlapp app script which stand for cleaned application with novel function

update details🚀:

1. When pause button is pushed, the text of the button will be changed into resume and vise-versa.
2. The auto-saving capability is added into our application with frequency of 10 steps per save.
3. The back-play function is added which is activated when the application is in pause mode and could display the history traffic condition from whenever the slide pointer designated.
4. The back-play process will use the history data rather than re-calculating them.

🏆2025.05.12 | the 3rd update | add the Road slope change trimmer for the 1st and 2nd road part; add the Save and Load button for saving / load of simulation data; add the Logger of whole software

update details🚀:

1. The 2 trimmers Road1 slope and Road2 slope are added for custom changing of road appearance with 2 modes: 1) directly change the slope number via re-typing the number in value box; 2) slightly change the slope value by using the step-by-step increase or decrease button in the step of 1 at a press time.
2. The function of Save and Load button is different from the auto-saving function in the last update which is to save the simulation info of simulation in this time. To be specific, the Save button is to let the software aware which auto-saving data belongs to this simulation when the user would like to take a look at his historical data. The Load data is to load the historical data by user interface.
3. The Logger part is to save every button press or accomplished operations at the format of time + operation content.

1 repository structure

This repository has 2 branches: Master and Interface_code. The master branch is consisted of source code on traffic flow simulation. The Interface_code branch is the latest branch where source code has been assemble into an interactive user interface.

To be noted that the interface_code branch also contains all useful source code in main branch, therefore, directly download interface_code repository should come in handy. In addition, the traffic_simulation2.m is the runner file for the source code part.

Last but not least the files and their corresponding of interface part can be listed as:

Example_Data.mat is the example traffic flow data used as data formulation examplary and demonstration;

app2.mlapp is the matlab coded application with 'App Designer' module which constain all source code of the lastest release (Beta version, with newest functions but unsatble) of our software;

clean_app_*.mlapp stand for the clean version of our software which will usually be realeased together with the 'app2.mlapp'. To be noted that the 'cn' means Chinese version interface and en stands for its English version conterpart.

cache_datarepository is to save the automatically cached data from software.

simulation_history repository is to manually save the simulation history from software.
