What do I do for a living ?

General Overview ::
My daily job is providing Consultancy Services in Road Safety, Operational Safety, Traffic Engineering and Management Services for various clients through my employer Sevenairs Consulting, which incidently, I'm the owner/director of !

Traffic Engineering ::
The design of a road improvement is much more complex than just dropping a few bricks in the road and covering them with tarmac... Indeed, many people believe this is the case and it takes some explaining to persuade them otherwise !!! I deal with a small aspect of the design process, but probably the most important bit, which I call the icing on the cake. Basically, the things all users see... Things like geometry, road markings, traffic signs, street lighting, traffic signals and often overlooked, the legal stuff.

Designing Roads ::
I could be here all night, but I've listed some issues below that need to be considered in the design process. Obviously the bigger the scheme the more involved the work and more of the items have to be considered.

:: Land ownership, use and planning issues
:: Highways economics, cost benefits and funding processes
:: Foundations, sub structure, soils and water tables
:: Water, surface drainage, cross fall, long fall, sewers and outfalls
:: Statutory undertakers, water, gas, electric, telecoms, other
:: Surface materials, macadam, concrete, loose materials and landscaping
:: Safety barriers, pedestrian guardrailing
:: Bridges, viaducts, tunnels and retaining structures
:: Traffic signs, road markings, street lighting, traffic signals
:: Traffic regulation orders, speed limits, parking control and other legal stuff
:: Technology, lane control, variable message signs, communications

The list isn't meant to be comprehensive, just gives you a taste for the complexities of the work. What you normally find is that many people specialise in one or two of the fields listed above. My skills are generally in the latter three items, but I also dabble in many of the other fields
