Performance Tuning of Coordinated Active Traffic Control Algorithm: Simultaneously Improving Corridor Safety and Mobility Performances

Table 2

Scenarios tested with different 𝑅_mobility and 𝑅_safety values.

	Scenario 1 (uncontrolled)	Scenario 2*	Scenario 3	Scenario 4	Scenario 5
𝑅mobility	N/A	1	8	8	8
𝑅safety	N/A	N/A	1000	3000	5000
Crash probability	11.6%	9.3%	7.5%	6.6%	9.7%
Mobility cost	911.4	390.1	487.6	551.4	597.0
Mobility cost comparisons**	N/A	−57.2%	−46.5%	−39.5%	−34.5%

Note: *in this scenario, the objective function considers only the mobility cost (i.e., 𝑅_mobility = 1 and 𝑅_safety = 0).
**Compared to the uncontrolled condition, mobility costs are measured by (14).
