CLAMP--A MODEL TO SIMULATE PARKING BEHAVIOUR IN TOWN CENTRES

摘要: This paper describes the computer simulation model "clamp" used to study effects of parking policies on traffic flows and speeds in London suburban town centres. The most important inputs are as follows: trip demand profile over course a representative day, terms travel activities, time day duration stay; times costs reach centre by car bus; supply cost off-street legal on-street illegal parking; flow characteristics road network for bus travel. is designed be flexible number definition demo-graphic groups, segments types. also operation at three different levels. First, individual arrivals simulated each "slice" day; second, conditions updated slice, finally several day-long periods can succession, with behaviour during "day" influenced preceding "days".
