Effect of vehicle type on highway traffic flow: Effects of vehicle type on speed, delay and capacity characteristics of highway traffic flow in the United Kingdom and Saudi Arabia determined by an examination of traffic data.

Description

The t h e s i s c o n s i d e r s t h e e f f e c t s of v e h i c l e
type on highway t r a f f i c flow. The e f f e c t s of v e h i c l e
type on t h e c a p a c i t y of t r a f f i c s i g n a l approaches are
examined by t h e experimental d e t e r m i n a t i o n of passenger

and i n a d d i t i o n s a t u r a t i o n flows and lost t i m e s a r e examined.

Observations of t r a f f i c flow on a r u r a l motorway a r e

A review is given of t h e e f f e c t s of v e h i c l e type on t h e design and o p e r a t i o n of t h e highway system in Saudi Arabia.
