Abstract

Computer simulation is a vital means for the examination of expressways and urban lanes and streets. Transportation experts concentrate on the arrangement and dissemination of traffic jams on roadways. The objective of this study is to calculate and analyses the travel time, delay time, degree of saturation, and level of service and travel speed in Jordan intersection in Baghdad, Iraq using Sidra software. The number of vehicles passing Jordan intersection was recorded by the author of this work from 7am to 3pm for four days. A simulation model has been used to assess the performance of the current intersection. Results demonstrated that the level of service (LOS) for Jordan intersection is D with (35 sec/veh) average delay and degree of saturation (0.996 v/c). It was concluded that Jordan intersection needs further developments like using intelligent transportation system application (ITS) to regulate traffic signals, whereby reducing traffic jam, using closed circuit TV (CCTV) might assist traffic office in identifying jam point to reduce traffic jam.

Highlights

Traffic jam happens when a volume of Traffic produces demand for more space as compared to the accessible street limit; this point is generally expressed as the degree of saturation

The average delay is adversely correlated with level of service (LOS)

Summary

Introduction

Traffic jam happens when a volume of Traffic produces demand for more space as compared to the accessible street limit; this point is generally expressed as the degree of saturation. There are various particular circumstances that cause traffic jams; the vast majority of them decrease the limit of a street at a given point or over a specific length. Around half of U.S traffic jam is repeating [2], and is ascribed to sheer weight of traffic; a major of the other half is attributed to the movement to traffic Ali used SIDRA software to assess the traffic flow in Roundabout and intersection in Bandar Baru. Ibrahim investigated the assessment of Models for roundabout capacity and performance estimation for using SIDRA, ARCADY, RODEL, SYNCHRO models and Highway. Examined the evaluation and enhancement of traffic operation for Al-Zeoat Intersection in AlRamadi city, using SIDRA traffic program [5].
