Just-in-time shipments in a truck-traffic coordination system

Frequent just-in-time (JIT) deliveries, nowadays widely spread throughout manufacturing and service industries, are considered to be a major cause of the deteriorating traffic situation. A truck-traffic coordination system that shifts truck traffic from rush hours into time zones of low traffic density is proposed. Very frequent JIT shipments become obsolete without directly restricting the number of shipments. Moreover, the concept encourages companies to use trucks that emit low noise and air pollution. The implications for JIT manufacturers are discussed and practical adjustments explained. The effect on the traffic situation as well as on the JIT part-supply scheme is demonstrated through examples.
