**TTs = 2.5%:**  
For DRAC \(\geq\) 3.35 m/s\({}^{2}\), the results in Table 5 show that increasing the TT speed limit reduced the conflict ratio (i.e., increased safety) by 0.05 to 0.24 for a traffic volume of 500 to 1500 vehicles/h/lane. This implies that the total conflicts in the after period (i.e., increasing the speed limit of TIs to 70 km/h) reduced from 0.76 to 0.95 times the total conflicts for the base case of 60 km/h TIs.
