BEATING A BOTTLENECK

  1. Compare a bottom diameter of a bottle and a diameter of its neck. How does this narrowing (necking) function when you fill a bottle and when you empty it? How does a similar narrowing (called a bottleneck) of a road influence traffic flow?

  2. Can you give any examples of bottlenecks in or close to Kyiv? What are the possible solutions to this problem?

  3. Read the texts. Complete the following table with the information from the text.

Country

Volume of traffic

Cause of the traffic problem

Age of the tunnel

Solution to the problem

Lebanon

New highway project near the battered Lebanese capital will ease congestion and hopefully boost tourism.

Since the end of the war in Lebanon in 1990, the country has started a massive redevelopment program. One of the priorities is the construction of infrastructure, particularly in and around the capital, Beirut, where about a third of the country's three million people live and work. For the majority the car is the principle means of transport.

A key arterial road carries commuter and commercial traffic north from Beirut. The existing dual carriageway has three lanes in each direction, but a hindrance to smooth traffic flow is a 40-year-old narrow tunnel with two lanes either way. This short tunnel is the only route through a rock outcrop and is a serious bottleneck.

The volume of traffic along the route is estimated at over 200,000 vehicles per day. The situation will be eased following completion of the first stage of the planned work, namely the 4km long section which includes a new road around the existing tunnel.

The project is for the construction of new carriageways and rehabilitation of existing lanes to provide a four-lane, dual carriageway, involving many bridges and underpasses, and four major intersections. When the new lanes are opened, traffic will be diverted from the existing carriageways which will be rehabilitated and upgraded. The new highway will eventually be extended a further 15 km.

Most of the bridges are founded on 800mm diameter reinforced concrete piles. The bridges are precast girders, prestressed on the ground and lifted into position by mobile cranes. The deck is an 8mm thick precast concrete slab forming part of the main deck poured above. This method was adapted to maximize on time and save on formwork. The total project has over 40,000sqm of formed concrete structures.
