Planning vs Implementation

On my way to Shah Alam via Federal Highway this morning to attend a function, I witnessed perhaps one of the longest and biggest car parking at the opposite direction. It was a big traffic congestion from PJ all the way down to the interchange of Shah Alam Stadium. I was made to understand that this is a common phenomenum on every working day. The volume of private vehicles patronising the roads is getting higher per day even though the car price is higher as well. Why are there less people taking public transport. Is that because of the insufficient of vehicles fleets or due to the problem of connectivity and accessibility? We have been debating the issue of traffic congestion decades ago and we have also suggesting public transport as the solution, but problem is remained even til now. My conclusion is the issue is not about failure of planning but rather the capacity of execution. Execution remains the bigger challenge and, sometime obstacle to the fruition of effective planning. Without execution done with planned schedule, a comprehensive and holistic planning is not going to work. Even though implementation is finally done, it will involve many changes and adaptation. For example, a ramp need to be built for a development but construction was deferred to later date due to financial problem might not be suitable anymore as solution to the traffic management as many motorists patronising the building would have developed other type of driving behaviour then. It is difficult to get them to change later, I presume. Hence, planning and implementation must go hand in hand or else the blame of failure in planning will always remain.
