Usage

1. Run MAIN_1b.m in MATLAB to create Figure.1b
2. Run MAIN_1c.m in MATLAB to create Figure.1c

Description

This script is used to create Figure 2 of the article:

Mullakkal-Babu, Freddy A., et al. "Probabilistic field approach for motorway driving risk assessment." Transportation research part C: emerging technologies 118 (2020): 102716.

MAIN_1b.m

This is the upper-level function that plots the variation of potential PDRF strength due to the road boundary object as a function of lateral spacing to the lane boundary, with different heading angles;

angleofImpact.m

This is a helper function that receives the angle of impact as the argument and outputs single step PDRF risk estimates

MAIN_1c.m

This is the upper-level function that plots the variation of potential PDRF strength as a function of lateral positions within the lane. The black lines represent potential PDRF strength for different k and red represents the potential PDRF strength for different offsets of the road boundary object.

roadSensitivity.m

This is a helper function that receives the values of coefficient k1 and offset as the argument and outputs single step PDRF risk estimates
