Abstract
The Tandem Sorting Strategy (TSS) is an approach to increase capacity in intersections with separate turning phases. Pre-signals are used so that only vehicles in one phase can approach the main signal and use more lanes for discharging. When the green split at the TSS approach exceeds a certain value, TSS efficiency is reduced. This can easily happen when the flows are significantly high in one of the phases. A case study illustrating this situation is presented. TSS is applied to a single approach and the signal parameters are optimized. It was found that TSS has higher capacity compared to No TSS even when the cycle length in TSS is shortened. It means that both capacity increase and delay decrease can be simultaneously achieved with TSS.
