ORAL ANSWERS TO QUESTIONS - INCREASE IN ERP GANTRIES AND HOURS - Social and economic impact
As with business, there are also many factors affecting work patterns and family life. However, even where ERP affects travel patterns in that some choose to avoid, say, the evening ERP on the CTE, there is also a flip side to the story. Others who were previously unable to get home early at all because of traffic jams are now able to do so if they wish, and can plan ahead with a much higher degree of certainty because of ERP. For example, after the gantry on the CTE before the PIE exit was implemented in November 2007, traffic volume between 6 and 7 pm fell by about 700 vehicles. But traffic speeds for the remaining 7,000 vehicles that continued to use the CTE increased from 34 kph to 50 kph. So 7,000 drivers now enjoy the benefit of a smoother and more predictable commute home. If we do not have ERP to deal with congestion, then motorists, and even large numbers of bus commuters, will get stuck in traffic jams, spend a long time on the road getting to work, and not be able to get home on time. This is hardly conducive to work and family life. By having ERP, we can be assured that commuters will get to their destinations on time, and give commuters a choice, rather than leaving everyone with no choice but to endure the daily grind of gridlocked traffic.
