Optimal control of arterial signals is critical for the effective operation of urban road network. With the
goal of providing reasonable allocation of bidirectional green time while maximizing general bidirectional traffic
progression along the arterial, this paper develops an improved general bidirectional coordinated progression model
for arterial based on Maxband model. In the model, a proportional coefficient of bidirectional bandwidth demands
is introduced and calibrated by adopting average link queue occupancy. The calibration method takes full account
of actual traffic volume and capacity of each link, which helps to provide optimal control performance. Additionally,
new constraints are added into the model and enable the model with two features: it can automatically select
two-way or one-way progression, and the involved intersection unit can be either one-phase-one-approach or
bidirectional symmetric release mode. The results of extensive simulation studies indicate that the improved
model outperforms existing methods, markedly increasing the utilization of available bidirectional green time.
