Bus rapid transit (BRT) system as a transportation mode has a higher occupancy rate and is more suitable for long distances. Sustainability issues and improving BRT performance to enhance customer satisfaction require performance evaluation of possible alternatives. For this end, four scenarios as 1) adding buses to the BRT line, 2) speeding up the BRT buses, 3) reducing delay time, and 4) increasing the capacity of buses were simulated with Arena 14. Then, we developed Grey Step-wise Weight Assessment Ratio Analysis (SWARA-G) approach to weigh evaluation criteria including sustainability and risk factors. We implemented Grey COmplex PRoportional ASsessment of alternatives (COPRAS-G) to rank scenarios. Findings show that adding buses to the BRT line is the best alternative for improving the performance of the BRT line 1 in Tehran.
