Traffic and Productivity in Ghana - Dynamic Lane Management


The post by ICTPost has raised a number of important issues regarding traffic and productivity. Since my return from South Korea a couple of months ago I feel a dip in my productivity; much of it
due to traffic congestion (and the associated stress) in Accra. Even though Seoul is a much bigger, faster and more stressful city than Accra one does not get stressed out to the extent of being fatigued or unnecessarily delayed due to traffic. One thing I noticed about the roads in Korean cities is that they do not use concrete pavements to separate lanes of roads feeding traffic to the Central Business Area. Instead they just use the markings. This sort of design makes it possible to dynamically manage lanes and worth considering in the design of our CBA feeder roads. 

With the aid of traffic lights, Dynamic Lane Management makes it possible to increase the number of lanes (hence increase the flow of traffic) in the direction where traffic is heavy (e.g. traffic to the Central Business Area of Accra in the morning) and decrease the number of lanes in the direction where traffic is less heavy (e.g. traffic out of Central Business Area of Accra in the morning). 

Still, on lane management our commuters seem not to know the significance of the outer and inner lanes. In some jurisdictions it is an offence for a private vehicle to use the outer lane; a preserve for public transport. While the outer lane is for public transport, the inner lane is supposed to be a speed lane. These provisions are not observed by commuters on our roads. Moreover, in some jurisdictions the speed lane can only be used by a private vehicle when there are 3 or more passengers in it. (e.g. South Korea). That leaves only the middle lane(s) for private vehicles carrying only one passenger.

Besides, lane management one other way of managing flow and traffic congestion is Telecommuting. If 50% of employee (public as well as private sector) who ride in private transport to work, telecommute to work we would be reducing traffic by 50%. This is feasible in the near future, given the investment in broadband and the national fibre backbone. What we need to do is to encourage  (through regulatory and legislative provisions)  real estate developers as well as telecom providers to extend fibre to the homes (FTTH). If the one million homes Government is trying to build, come network ready with fibre connectivity to the national back bone we should be in a position  to telecommute interactively - with Multimedia features.

Still from the technology perspective, almost all Korean vehicles have navigators with GPS mounted on them. With these technology one can make inform decision regarding the shortest route to a destination, and the traffic landscape.

One other thing I noticed in South Korea is that the Ministries, Departments and Agencies (MDAs) are not all located in the capital (Seoul). Some of the MDAs are in Daejeon; a city about 300Km from Seoul. Even though this arrangement may have been motivated by security reasons - the closeness of Seoul to North Korea, as a side effect it diverts some traffic from Seoul. Ghana may not be  at war with her neighbours, but I think for security as well as for traffic management reasons we should also consider relocating some of the important government establishments/agencies to places outside Accra. In this day and age of ICTs the geographical location of an entity/establishment does not matter if the appropriate infrastructure and systems are put in place. Besides, do we ever factor the location of important establishments/entities in our Contingency and Disaster Planning?  Do we ever consider the effects of Tsunami on the Central Business Area and for that matter on Government Business? All the important establishments are located on  High Street or close to the sea - The Caste (Seat of Government), The Indece Square, The Accra Stadium, The Arts Centre, The Kwame Nkrumah Mausoleum, The Bank of Ghana, The Ministries, The Courts, The National Library, SFO, CHRAG, The National Lotteries, The National Theatre, The Science Museum, The State House and Parliament, etc  Relocating some or all of these entities outside Accra - e.g. towards Dodowa, if not in another city, would not only secure them from the effects of a Tsunami, but I guess would also divert 50% of the traffic from Accra.

And while I was in Norway in the 90s I also observed that a ring 10km from the Central Business Area  was constructed around the city I lived in. At the ring Car parks were built and all private vehicles were made to park at the ring and the occupants were made to take public transport - trams and buses. A heavy fine was imposed on those private commuters who wanted to ride in their vehicles into the city. Meanwhile, at the periphery of the city were malls hosting all the shops one can find at the central business area (CBA). But the good thing about shopping in those malls is that the goods there were cheaper than the same goods in the sister shops at the CBA. I guess such an arrangement could constitute part of the solutions to traffic management. We need to have malls, good schools, hospitals/polyclinics etc at the periphery of Accra - e.g Dansoman, Adenta, Sarkumono, Taifa etc


The message being put across here is that Over-Concentration is the cause of traffic in our cities. We would succeed in managing the traffic if we free the CBA of some of the establishments and provide some incentives for staying at the periphery or institute some penalties for wanting to do business at the CBA.
