JUST-IN-TIME SHIPMENTS IN A TRUCK-TRAFFIC-COORDINATION SYSTEM

Frequent just-in-time (JIT) deliveries, nowadays widely spread through out manufacturing and service industries, are considered to be a major cause of the deteriorating traffic situation. A truck-traffic coordin ation system that shifts truck traffic from rush hours into time zones of low traffic density is proposed. Very frequent JIT shipments becom e obsolete without directly restricting the number of shipments. Moreo ver, the concept encourages companies to use trucks that emit low nois e and air pollution. The implications for JIT manufacturers are discus sed and practical adjustments explained. The effect on the traffic sit uation as well as on the JIT part-supply scheme is demonstrated throug h examples.
