Abstract:
This paper presents a generalized diversion control model for freeway incident management that is capable of concurrently optimizing the detour rates and arterial signal timings over multiple roadway corridor segments between the freeway and its neighboring arterial. To capture various operational complexities due to the interactions between multiple diversions, this study has extended the model developed in our previous work (Liu et al., 2009), and integrated it in the overall corridor optimization process. The proposed generalized model based on reliable sensor data can produce the following three types of control parameters: 1) a set of critical upstream off-ramps and downstream on-ramps to be used for detour operations; 2) dynamic diversion rates and detour destinations for traffic at those critical upstream off-ramps within the control boundaries; and 3) arterial signal timings during the control time period. Numerical tests with a hypothetical corridor network have demonstrated the potential of the developed model for use on incident management.
