Saudi Arabia is undergoing a series of updates to its transportation network in a bid to Enhance Traffic flow Prices and improve security – Mike Woof reports
The huge increase in the usage of motor transportation globally since the onset of the 20th century has changed every nation on Earth. But no country has shifted more radically than Saudi Arabia, the world’s top petroleum producer. At the beginning of the 20th century, Saudi Arabia’s population was small and the nation had several businesses while it’s currently heavily industrialized using its tremendous oil manufacturing slaking the world’s demand for fuel. The nation’s population growth curve proceeds, as well as the Saudi Arabian Government, which has set aside huge amounts of cash to further build up the infrastructure. Public and private transport may both profit from this huge investment program. The Saudi Arabian Government has allocated a budget of US$266.6 billion into its 2013 funding so as to execute a multimodal transport system that contains new railways, metros, traffic programs, highways, buses, and streets.
But, the terrain and climate in Saudi Arabia supply big challenges to a street building. Temperatures could be ferociously large, especially in desert regions and this has required a careful choice of road surfacing materials to make sure there is not any deformation, particularly under heavy traffic loads. Meanwhile, the nation’s high mountain ranges pose various issues, and in South Western Saudi Arabia that these are around 3,000m large.
However, despite those challenges, new connections are assembled and even a number of the nation’s formerly inaccessible areas can now be achieved by new streets. 1 key project is for the building of a $5 billion bridge linking Saudi Arabia and Egypt, but this seems likely to be postponed until the present political scenario in the latter state has stabilized.
Capital Riyadh has witnessed perhaps the most striking growth. In less than 100 years that the town’s population has increased by a factor of 328. Back in 1918, Riyadh’s inhabitants were only 18,000 compared to some not-inconsiderable 5.9 million now. The infrastructure of Riyadh has increased in phases also, together with the remainder of Saudi Arabia. But, demand has outstripped congestion and capacity could be acute at peak travel times.
To manage this matter, the Saudi Ministry of Transport has established a comprehensive road-building program to tackle both the capacity and security problems and which includes advanced traffic management and ITS technology to improve both traffic circulation and security. The Netherlands based Royal Haskoning DHV has been given the job of identifying 30 visitors bottlenecks in Riyadh and to discover solutions that will improve traffic circulation at these various places. The update into the King Abdullah Road such as has included a potential gain from 190,000 520,000 vehicles/day, by increasing the width of this road and improving the design of their junctions.
Riyadh’s initial ring road, the north-south King Fahd Road, and the east-west Makah Road are the priority projects for developments, with a focus on fostering safety and supplying more off and on-ramps. All these are being enhanced through the construction of new bridges and tunnels in a collection of intersections, while fresh traffic corridors will operate upon the city.
With this four-phase program, both new exit and entrance points will be constructed between support streets and the main carriageways along freeways, while the street layouts are being standardized. There’s also a move to different parking spaces from the carriageways in addition to constructing new pedestrian ways.
The earliest of those four infrastructure development phases intended for Riyadh is breaking US$2.74 billion and can be focussing on finishing construction of Riyadh’s 2nd and 3rd ring streets, such as the construction of 38 tunnels and 15 bridges. Some 100km of existing streets will be improved while 244km of new streets will be constructed.
Costing an additional $2.96 billion, the next stage of Riyadh’s road transportation update will see developments to 199km of present links and construction 71km of new streets. Most work will be finished on 11 big paths while 30 brand new tubes and 50 bridges of different sizes will be assembled.
For the $2.74 billion next stages, 58km of new streets will be constructed while 158km of current links will be made better. This will definitely see work being completed on 14 big streets in addition to the building of 40 tunnels along with 29 bridges.
Largest of all is the fourth stage, which is costing $4.9 billion and now demands 118km of new streets in addition to developments to 322km of current streets. Work has been completed on 41 big paths while 46 brand new tunnels and 86 bridges have been assembled.
One of the big parts of work was the 186 million project to build a tunnel under the six-lane King Fahd Flyover. This cut and cover work has been completed while the very busy street stayed in use, which makes it very hard for the companies involved, builder Saudi Oger and designer Buro Happold. The flyover includes 15 spans, built-in sections employing post-tensioning, and the layout called for the tube walls to be constructed within 100mm of its relatively shallow foundations.
Buro Happold developed a novel design for your builder with a distinctive load transfer arrangement together with the bridge piers. Extensive modeling was obligated to make sure the motion of the stone wouldn’t result in issues for tunnel excavation. The cut and cover tube design was excavated to a depth of 13m, with segments 180-700m long. The tunnel roof segments have been precast while the reinforced concrete segments lie on pad foundations.
As part of its strategy to increase road safety and reduce travel times, the Ministry of Transport from Saudi Arabia commissioned a building oversight bundle for its Riyadh Second Ring Road South East Leg and many streets and junctions in Northern Riyadh. The project comprises the construction of main roads, service roads, bridges, street lighting, drainage system, as well as the relocation of existing utilities. The centerpiece of the package is your Riyadh Second Ring Road South East Leg, which comprises three chief junctions and five connection streets. The bundle also has street lighting to the 3 chief streets, the Riyadh – Taef Expressway, the Riyadh – Kharj Expressway, and Thumama Road.
The range of work with this includes complete project management solutions including job scheduling, contract management, progress reporting and control, documentation management, and technical assistance. Additionally, it covers quality management and quality assurance about the building of bridges and roads such as alerting and signage, intersection signaling, road lighting, and stormwater drainage. In this, there’ll also be an overview of this program of functions the builders may use to comply with the contract requirements and significant preparation standards and strategies. Along with the oversight bundle also must assess the builder’s comprehensive plan, covering aspects like gear mobilization, material procurement, and delivery of drawings. Another aspect is going to be a review of the contractor’s approach statements, employees’ installation schedule, and allocation of responsibilities, in addition to observation of construction progress involving the subcontractors and providers.

The investment round the Gulf
The Gulf area as a whole is investing heavily in developing its transport infrastructure, together with Saudi Arabia with one of the biggest programs. Transport is essential to the nation’s economy and incorporating the street network in other ways is a vital endeavor. Saudi Arabia has three international airports situated at Jeddah, Damman, and Riyadh. These airports also act as the principal hubs for national flights. Meanwhile, there are six main seaports in Saudi Arabia. Every one these airports and airports need connecting to the street network to make sure passengers may reach their flights also that merchandise can stream in and out of the nation.
There’s a strong focus on enhancing important paths within Saudi Arabia. According to the Saudi Ministry of Transport, crucial inter-city links comprise the 257km Dammam – Abu Hadriya – Ras Tanura Highway, the 157km Khaybar – Al Ola Highway, and the 421km Makkah – Madinah Al Munawarah Highway. They also incorporate the 383km Riyadh – Dammam Highway, the 317km Riyadh – Sedir – al Qasim Highway, the 750km Riyadh – Taif Highway, and the 750km Taif – Abha-Gizan Highway.
The Saudi Ministry of Transport established numerous street design jobs across the nation in accord with this 20- year prioritization app for secondary and primary streets. Studies have been commissioned for important main streets in the Riyadh area. These include the dualling of a 90km stretch of the Riyadh — Khurays – Ehsaa Road and developments to Exit 14 of those Riyadh Eastern Ring Road. They also include the building of this 15km Second Ring Road Link (Sheikh Jaber Road Extension) involving Dammam Road and Prince Salman Road along with the update of this 11km Sheikh Jaber Road between Makkah Road and Dammam Road.
The range of work has contained the research, surveys, and layouts necessary for the job tenders. These cover a collection of tasks analyzing the topography, hydrological and hydraulics facets, geology, traffic and flow, and geotechnical investigations such as bridges. The job also appears into route choice, concept, preliminary and detailed layouts of 121km of double streets and 2km of single carriageway roads, in addition to the concept, preliminary and detailed layouts of 31 grade-separated interchanges. It’s easier to move and change places in the country because of it. That’s why a lot of professional furniture transfer companies (visit http://www.masa7.com/شركة-نقل-عفش-بجدة for more info) exists today in Jeddah.
Looking farther ahead of the analysis is exploring designs for 136,000m² of just supported and 32,000m² continuously-supported bridges comprising solid slab decks, T ray decks, box girder decks, pre-stressed decks, and metal beam decks. Additionally, this part will comprise 34,000m² of bridges that are unique using suspension or cable-stayed layouts. Other elements include a comprehensive design for the street light in addition to the landscaping and drainage for 51km of streets and 31 interchanges. And for everyone these elements a value engineering exercise will be completed until the detailed design phase can begin.
Saudi Arabia invests in road safety
Statistics reveal Saudi Arabia to have a significant road safety issue, in which the police are currently addressing tough enforcement measures combined with the introduction of complex technology. Back in 2012, there was a mean of 19 street deaths occurring/day in Saudi Arabia, costing in excess of US$6 billion in most with $250 million/year on healthcare alone. The most important reason for traffic accidents is by reckless drivers along with the General Directorate of Traffic reports that individual factors are responsible for approximately 85 percent of all automobile crashes. Approximately twenty-one of crashes are the result of drivers failing to stop for red lights and 18 percent because of prohibited U-turns, whilst speeding, abrupt stops, the usage of mobile phones, and competitive driving accounts for the remainder.
A huge section of the budget will go towards the installation of a number of the most recent innovations in transport technology. Schneider Electric has just completed the organization’s first smart transportation system, SmartMobility Road Suite, on a 6km stretch of King Abdullah Road at Riyadh. The system handles four tunnels across the expressway and because of its installation there’s been a marked decrease in the number of crashes in addition to travel times over the city in addition to a fall in gas consumption. By tracking real-time traffic, the machine can give information directly to the drivers and authorities. This allows for a quicker reaction to events and enabling drivers to select optimum routes. Additionally, an automatic traffic management system was introduced throughout the country for a deterrent to competitive driving. This system makes sure that drivers that are speeding or run red lights could be recognized and fined, though an online system is comprised of those geo-locates leasing automobiles and highlights people being pushed carelessly.
