GREEN TRAFF
C SOFTWARE
Software decongesting cities
Location: Matbuat Avenue, Baku, Azerbaijan
Number of intersections: 5
This case study is an example of Green Traffic Software tool applied to a real urban city arterial. Matbuat avenue is a part of the Western section of the Baku city circular arterial. It is 1930 m long and contains 5 intersections, none of which have left turns. An interesting feature of this case is that inbound and outbound average vehicle velocities are different.
For the given set of phase splits in all arterial intersections, GTS provides multiple coordination schemes.

Input arterial data:
Number of traffic lights
Distances between them
Recommended vehicle velocity
Split phasing
Cycle lengths and the desired common cycle length
Output:
GTS provides the arterial portrait, showing all possible bidirectional timing plans with 1 sec resolution. In total, 2176 timing plans are possible, 33 of them provide the maximal sum bandwidth of 72 seconds. This is 50% more than the sum bandwidth of 48 s (see the asterisk in the brown rectangular) obtained for this case in the article cited above.
Each green asterisk leads to a particular timing plan: offsets and phase sequences ("orders") are shown together with the time-space diagram. The dark green asterisks mark the bandwidths pairs with maximal sum. The blue circles mark the bandwidth pairs that are impossible in this arterial.
Three arterial timing plans below correspond to the bandwidth pairs marked by green squares in the AP.
Inbound and outbound bandwidths are indicated in green and blue, correspondingly.
The inbound direction in the diagrams is top-down, the outbound one is the opposite.
Inbound bandwidth: 52 seconds
Outbound bandwidth: 20 seconds
