DB-Sim

A data driven and queue-based simulation tool for ETE

Goals

calculate evacuation time faster and more accurately

Methods

• build basic iterator model[db-sim Framework]
• build ml model
• data driven model integration
• Experiment

TODOLISTS

Framework

• parse xml from config
• boost library support
• logging support
• basic iterator develop
• xgboost,randomforest c++ support
• refacting db-sim manage
• refacting config manage

Model

• poolnum -> buffernum
• buffernum -> outflow
• sample for every link and node
• add pool and buffer sample
• train model for each node
• import ml model(trained by python and predict by c++)

Plans

V0.1.3

• add param configure for better tune.
• add super-dest-point process

V0.1.4

• add [poolnum -> buffernum] Model
• finished basic iteration for simulation.

V0.1.5

• add 2out->1in intersection analyais(discard)
• add rotary island intersection analysis(discard)

V0.1.6

• add long path analysis
• add circle module
• precise link desc with buffersize
• update vehicle generator

V0.1.7

• road condition display

To Be Continue~

Usage

Settings

• config privoid traffic network and evacuation demand with xml.
• src do simulation
  • core core code for simulation
  • utils some userdefined or 3rd necessary tools ,example parse xml tools
• test some test case for this project
• data train and test data

dbsim [options] [ceil|test|gawron|fete] :
  -h [ --help ]           show help
  -c [ --config ] arg     user defined config file
  -s [ --sample ] arg     sample for node and link
  -S [ --simulation ] arg simulation for fast ete
  -t [ --test ]           Test each model

build

cd ${PROJECT_DIR}
mkdir build
cd build
cmake ..
make

Result

link 2571 and 2581

The DB-Sim method is closed with origin mathod ,but run much faster.
