It is not that Global Navigation Satellite System for traffic congestion resolution will not work,
At its core is about signals, & such are only electromagnetic frequencies which can be amplified by many more signal repeaters built upon each lamppost within the critical traffic congestion capable zones, to ensure signal boosting of 24/7 100% signal strength to Satellites come whatever environmental or weather conditions, akin to laser power, & even such is not guaranteed at 100% within harsh environmental conditions
Such comes at high energy, infrastructure & labour's costs, & worse, it still needs a backup system - gantries to ensure that a citizen had or had not entered the critical zone inorder to reslvove disputes, which means additional labor & maintenance costs to taxpayers public...
In the end, taxpayers citizens will ponder - is ERP 2.0 necessary or even cost & operationally effective than ERP 1.0 ?
