Management of Al-Khaldiyah Road (Al Khobar, KSA) in Order to Optimize Safety and Improve Sight View. American Journal of Traffic and Transportation Engineering. Vol. 2, No. 1, 2017, pp. 6-9. doi: 10.11648/j.ajtte.20170201.12 Received: March 2, 2017; Accepted: March 23, 2017; Published: April 15, 2017 Abstract: Al Khaldiyah is a regional road situated in west-south of Al Khobar (KSA), precisely in the area of Half Moon Bay. It is characterized by four lines – which become six lines in some places – in both directions extending over about 10 km length. The road extends between the bridge near the Air Force Base and Half Moon Bay Road. Many accidents have been observed in this road notably over the last two years. Many injuries and deaths were recorded; some of the victims were PMU students. Consequently, management of the road to eliminate or reduce accidents to a large extend becomes imperative. The main goals of this paper are to propose sustainable solutions for the purpose optimizing safety and improving the sight view of the road by designing some appropriate junctions including bridge and tunnel in the critical locations. The solution retained for the purpose of this project consisted on the prevision of three different junctions in this case: tunnel, tunnel/roundabout and bridge.

Introduction The Kingdom of Saudi Arabia has a network of internal roads sophisticated and modern and has a total road length of about 160 thousand kilometers of which about 47 thousand kilometers are paved roads linking major centers [1]. In Saudi Arabia the motor vehicle is the main means of transportation. However, between 1971 and 1997; 564 762 people died or were injured in road traffic accidents, a figure equivalent to 3.5% of the total population in Saudi Arabia [2], [3], [4] and [5]. They reported that during this period 66 914 people have died on the roads in Saudi Arabia due to road accidents, amounting to one person killed and four injured every hour [6], [7] and [8]. The main goal of this project is the management of Al-Khaldiyah road in order to optimize its safety and improve its sight view. The project is mainly concerned by the proposition of sustainable solutions for the purpose of optimizing the safety use of this important road and also improving its sight view. This includes: i) the design of some appropriate junctions in order to increase convenience, comfort and safety while at the same time enhancing the efficient movement of all road users, and ii) The minimization of traffic conflicts locations at these junctions. A good design should aim at minimizing the severity of potential accidents at these points. 2. Description of Al-Khaldiyah Road Al-Khaldiyah road, nicknamed in the past as the abundant road, is situated in the eastern region of the Kingdom of Saudi Arabia. Al-Khaldiyah is a regional road situated in west-south of Al-Khobar, precisely in the area of Half Moon Bay. The road is considered as subdivision road linking the cities of Al-Khobar, Dhahran and Dammam, along a distance or a length of about 9.8 kilometers and an actual width of 19.6 m. However the allowable design width of the road is around 60.0 m. Al-Khaldiyah is an important and a vital road in the Half Moon Bay. It provides direct access to many local beaches and notably to PMU University. It is used daily and extensively
