In an effort to improve the pricing mechanism, and, to introduce real-time [[variable pricing]],<ref>{{cite news| url=https://www.nytimes.com/2008/03/16/automobiles/16CONGEST.html?ex=1363320000&en=66db1c235736c7ea&ei=5088&partner=rssnyt&emc=rss| author=Ken Belson  |title= Importing a Decongestant for Midtown Streets | work=The New York Times|date=2008-03-16 | access-date=2008-04-06 }}</ref>
Singapore's [[Land Transport Authority|LTA]] together with [[IBM]], ran a pilot from December 2006 to April 2007, with a [[Traffic estimation and prediction system|traffic estimation and prediction tool]] (TrEPS), which uses historical traffic data and real-time feeds with flow conditions from several sources, in order to predict the levels of congestion up to an hour in advance. By accurately estimating prevailing and emerging traffic conditions, this technology is expected to allow variable pricing, together with improved overall traffic management, including the provision of information in advance to alert drivers about conditions ahead, and the prices being charged at that moment.<ref>{{cite web| url=http://www.planetizen.com/node/26091 | publisher= PLANETIZEN  |title= Predicting Where The Traffic Will Flow | access-date=2008-04-06 }}</ref><ref>{{cite web| url=http://www-03.ibm.com/press/us/en/pressrelease/21971.wss | archive-url=https://web.archive.org/web/20070901091248/http://www-03.ibm.com/press/us/en/pressrelease/21971.wss | url-status=dead | archive-date=September 1, 2007 | publisher= IBM Press release |title= IBM and Singapore's Land Transport Authority Pilot Innovative Traffic Prediction Tool | date=2007-08-01 | access-date=2008-07-15 }}</ref>

In 2010 the Land Transport Authority began exploring the potential of [[Global Navigation Satellite System]] as a technological option for a second generation ERP. LTA objective is to evaluate if the latest technologies available in the market today are accurate and effective enough for use as a congestion charging tool, especially taking into consideration the dense urban environment in Singapore. Implementation of such system is not expected in the short term.<ref>{{cite web|url=http://www.channelnewsasia.com/stories/singaporelocalnews/view/1066660/1/.html|title=Satellite navigation ERP and electric cars possible on future road system|author=Channel NewsAsia|publisher=CNA|date=2010-06-10|access-date=2012-01-02|author-link=Channel NewsAsia|archive-date=2010-07-01|archive-url=https://web.archive.org/web/20100701192138/http://www.channelnewsasia.com/stories/singaporelocalnews/view/1066660/1/.html|url-status=dead}}</ref>
