Despite jams on the controversial Bus Rapid Transit corridor in the Capital, transport authorities on Sunday claimed that the situation had improved since the trial runs began last Sunday. Transport Commissioner R. K. Verma said: "The traffic flow on Sunday was smooth and improving. We are still working on changing the signal pattern and hopefully a new one should be in place by this week.' Another official added: "None of the signal timings proposed has worked out well, so we have to keep seeing alternatives.' According to the traffic police, Sunday being a holiday is not indicative of the actual performance given the reduced traffic on the day. Some adjustments such as keeping light-goods vehicles off the motor-vehicle lane were announced on Saturday and were put in place on Sunday. Meanwhile, an increase in congestion has been observed on alternative routes.
