Anyone familiar with Bangkok in the 1990's, before the urban railways were built, will recognise the strategy of 'self-limiting congestion' (or 'do nothing') that Phuket is now experiencing. It's the inevitable result of decades of propulation and income growth with no increase in transport capacity.
'Self-limiting' means that congestion was the main restraint on car use. When it might take several hours to drive a few kilometres only essential trips will be made.
In Bangkok, the government made no serious attempt to manage the gridlock at ground level and instead embarked on a strategy of building elevated roads and railways above the chaos. For various reasons, building new infrastructure is much more attractive than trying to manage the chaos which would have required intensive traffic management and enforcement. and restraints on car use.
Lacking capability and political will to manage traffic, and with severe constraints on building elevated highways, 'self-limiting congestion' in Phuket is now inevitable. The proposed new roads and LRT cannot provide significant relief while demand continues to escalate. As traffic density increases more junctions lock up and the installation of simple fixed-cycle traffic lights without vehicle actuation increases delays in every case .
The Governor clearly does not want to acknowledge these uncomfortable truths, and he resorts to token measures such as diverting main road traffic 'to small roads'. The consequences of such a strategy are very negative, spreading danger, noise, pollution and congestion to sois and residential streets and creating more junction conflicts.
