Delay, Queue length, flow, signal timings Websters Delay Model, Akcelik Delay Model and the HCM (2000) Delay Models Results from existing models not comparable Background*

Performance of intersections Unwarranted traffic signals Studies on traffic performance are still limited. Many intersections and roundabouts at capacityBackground*

Statement of the problem

Signals offer solution to all intersection delays?? Signals installed at most high traffic intersections No specific operational analysis conducted Consideration that unwarranted signals result in delays. *

_General ObjectiveDevelop a model that relates delays to queue lengths and flows*

Specific objectivesApproach queues, flows and delays when signals are working Approach queues, flows and delays when signals are not working Compare intersection queues, delays & flowsDevelop a model*

Significance of the studyPlanning on installation of traffic signs on the junctions Whether traffic signals should operate continuously *

Justification KCCA currently identifying, preparing detailed design critical intersections Whether traffic signals are the ultimate cureVenturing in investments that are not warranted. *

ScopeJinja Road Junction, Wandegeya Junction, Nakawa Junction.Peak periods: Monday Friday 07:30 am 08:30 am Off peak periods: Monday Friday 10:30 am 11:30 amIntersection delays, queue lengths and flows*
