Usage

Running variations of particle filters:

1. Standard PF: run main_pf_creeping.m, set spatial_correlation as "false"
2. PF+SCNM: run main_pf_creeping.m, set spatial_correlation as "true"
3. PAPF: run main_pf_dual.m, set spatial_correlation as "false"
4. PAPF+SCNM: run main_pf_dual.m, set spatial_correlation as "true"

Change traffic scenarios:

In main_pf_creeping.m or main_pf_dual.m

1. Set test = 1 for freeflow traffic with overtaking
2. Set test = 2 for congested traffic
3. Set test = 3 for queue clearance
4. Set test = 4 for creeping traffic

Toggle image display:

1. Set show_sim = true to turn on simulation plots, for example:

2. Set `show_est = true` to turn on estimation plots, for example:
