Numbers to help avoid road delays

CITY traffic officials are planning to introduce a congestion index through multi-media platforms to help motorists avoid delays.

Shanghai Traffic Information Center has begun releasing the index on a trial basis on its Weibo account at

The center said it was planning to broadcast the index on TV and radio platforms soon.

The index system uses numbers up to 100 with a bigger number indicating a worsening of traffic conditions.

Center officials said an index above 50 would indicate major congestion and when it reached near 100 that would mean serious hold-ups.

Currently, the city's overhead signs adopt a three-color guidance system with red, yellow and green representing different traffic conditions.

The number index system would be an improvement, officials said, by allowing motorists to gain a more accurate picture of changing traffic conditions.
