Basically, developing countries restrict private car use, after chronic traffic jam does harm on economic activities.
But, Singapore takes advanced measures against traffic jam. Before causing serious traffic jam, Land Transport Authority predicts possibility of traffic jam and restricts car use.
Singapore has long installed ERP, automatic toll gate systems even on ordinary roads. The country has a good command of diverting people into public transportation.
