Transportation Engineering
The movement of people and goods is an essential requirement for the growth and development of any nation. If a society wishes to develop and grow economically and socially, it must have a strong internal transportation system and must also be highly accessible to its immediate neighbours and the greater worldwide community. While a nation’s economic standing is invariably improved by virtue of upgraded transportation systems and hence its accessibility, this improvement comes at a cost. Transportation pollutes the air and water, it changes the environment and impacts upon the natural beauty of the area, it consumes resources of land, materials and energy, and is not without danger, which in the worst case, results in loss of life.
Dannion’s transportation side of the firm applies technology and modern engineering practises to recommend transportation schemes that will be fast, efficient, convenient and comfortable, while also being safe and environmentally friendly. We also strive to work with government and the public to ensure that the highest quality transportation systems are constructed within the constraints of available budgets and in accordance with prevailing social policies.
More specifically, Dannion provides services at each phase of the provision of a transportation system, from the pre-planning phase, where information is collected to the planning phase, where the problem to be solved is defined and various alternative solutions are assessed to the design phase, where specifications of all features of the transportation system are defined to the construction phase, which covers all aspects of the building phase to the operations phase where the interaction of all forms of traffic is assessed to continually optimise the capacity and safety of roads and highways.
Traffic Engineering
This subspecialty of transportation engineering is the means by which the transport system is provided, managed and controlled. The ultimate goal of traffic engineering is to provide safe and efficient movement of persons and goods on roads and highways. Traffic engineering measures generally operate by modifying the travel conditions for existing traffic, or by influencing the pattern of movement. The objectives of these measures include improvements in accessibility, mobility and the environment within the area.
Dannion, working closely with governments to address traffic design issues at localized sites or within substantial networks, provides traffic engineering expertise in the following areas:
- Intersection Design and Operation
- Roundabouts
- Street Lighting
- Traffic Calming Measures
- Traffic Surveys/Counts
- Traffic Signage and Markings
- Parking and Loading studies and analysis
- Pedestrian facilities
- Traffic Calming
- Traffic Signal timing and optimisation
- Data collection
- Travel demand forecasting and modelling
- Road Safety Studies
- Traffic Accident Analyses
Utilising engineering methods and modern quantitative modelling and simulation techniques, Dannion assesses various measures of performance for the schemes proposed inclusive of accident risk, environmental impact, system capacity and travel time, in an effort to determine the preferred implementation option which optimizes road space, maximizes safety and capacity, and minimizes delays and negative impacts on the environment.
As part of our remit on the East Coast Road Project, Dannion implemented various traffic engineering measures, inclusive of the design and construction of a roundabout junction in the city of Castries, upgrades of Cul de Sac, Deglos and Marc junctions, and the placing of traffic signs and delineation of road surface markings as necessary along the route. We also provided the last two services in the form of designs for the West Coast Road Project.
