Delays to Traffic Caused by the Movement of Abnormal Indivisible Loads

摘要

Studies have been made of the delays caused to other traffic by the movement of abnormal indivisible loads. This report gives results for eleven load movements which were observed over a total distance of 1264 miles on all-purpose, most by single carriageway, roads. Average delays are given in terms of minutes per vehicle to the overtaking and to the opposing traffic, and also in terms of vehicle-hours of delay per mile travelled by the load; for both traffic streams together the latter figure ranged from 2 to 16 vehicle-hours for the different loads. The cost, per mile travelled by the load, to other traffic and to the police is also estimated. (Author)
