Abstract
This paper simulates, analyzes, and compares, for two case studies (one
synthetic freeway and one real-life freeway), the behavior of Logic-Based
Traffic Flow Control (LB-TFC), an integrated control strategy for Ramp Metering
(RM) installations and Variable Speed Limits (VSLs) that was proposed and
derived in the first part of the work ('Part 1: Controller'). For the first
case study, which was presented in the first part of the work, the control
performance of LB-TFC is compared with the ones obtained with the optimal
solution and with the Mainstream Traffic Flow Control (MTFC) + PI-ALINEA
algorithm. Moreover, the robustness of the considered controllers is analyzed
for this case study concluding that LB-TFC is quite robust, specially when
comparing with MTFC + PI-ALINEA. For the second study (a stretch of the
ring-road freeway SE-30 in Seville, Spain), data from 10 different days have
been used in order to simulate the performance of the considered controllers
using real data for the afternoon peak period. In order to properly deal with a
bottleneck with a dynamically changing number of lanes, the equations used for
MTFC + PI-ALINEA have been slightly modified for the second case study. For
both case studies, LB-TFC provides a robust performance that, in most cases, is
close to the optimal one and that improves the reduction in the Total Time
Spent (TTS) obtained with MTFC + PI-ALINEA. Moreover, this paper studies the
tuning of the control parameters and the advantages and disadvantages of
LB-TFC.
