The key performance indicators have been shown in the Table 4.1.

The roundabout was also analysed with a single lane at the southern Loop Road
approach but the roundabout failed in its operational capacity because the traffic
demand at this approach is high and requires two lanes. Hence two circulating
lanes are recommended with two approach lanes and two receiving lanes.

(ii) Loop Road /E5 & B3 Access Roundabout
For the purpose of capacity analysis the roundabout was designed with 1

circulating lane having width of 7m and central island with diameter of 10m. The
layout of the roundabout has been illustrated in the Figure 4.2.

The analysis shows that the roundabout works very well as the key performance
indicators are according to DMR standards. The maximum queue at the Southern
