Google Maps with real-time traffic information is now available in 12 more cities in India- Kolkata, Coimbatore, Lucknow, Surat, Thiruvananthapuram, Indore, Ludhiana, Visakhapatnam, Nagpur, Kochi, Madurai and Bhopal. This traffic feature, available on both mobile and desktop versions of Google Maps is now available in 34 cities in total. Google Maps makes traffic information available for all national highways and expressways in the country. Once the Traffic layer is turned on in Google Maps, commuters can see routes mapped out in different colors, indicating the different speed of traffic on those roads. Green means there are no traffic delays on the road, orange indicates a medium amount of traffic and red means heavier traffic congestion. While in Navigation mode, Google Maps will also use real time traffic information to more accurately estimate the time of arrival and to provide options for alternate routes if there are faster options available. Earlier this year, Google launched voice-guided Navigation instructions in the Hindi and Indian accented English language on Google Maps for mobile, as well as the integration of Indian Railways schedule information within Google Transit.
