The MMDA has just expanded its Traffic Navigator(TNAV) service today.
The minor expansion completed the streets along Quezon Avenue starting from Sgt. Esguerra all the way down to Mayon Street. Unfortunately, it seems that the mobile TNAV app is still in the process of of being updated as it still doesn't have the complete list of streets along Quezon Avenue.
There's still no news of a more comprehensive expansion and update (to include other major streets, i.e. E. Rodriguez Sr., Makati's major streets, etc) of the TNAV. MMDA Traffic Discipline Head Yvez Gonzales tweeted that it will still take a long time for that to happen.
