Traffic diversions are commonplace for roadworks or large infrastructure developments requiring closure of public space. Planning proper road diversion is a “fine art”, aiming to balance the interests of different road users:
A Telraam network can assist in a number of ways for managing and preparing for this traffic:
The primary goal of any temporary diversion is to provide safe alternative routes to road users in order to reduce any inconvenience as far as possible during construction works that can sometimes take weeks or months. Those plans require good baseline data for developing models that will be used to make plans for any contingencies.
However, it’s hard for planners to set optimal road diversions that take into account all routes, and also because in some cases it will be easier for motorists to ignore any signposted road diversions and take a sat-nav directed shortcut via local roads, causing nuisance for local residents.
Ongoing monitoring helps to understand if road diversions are being adhered to, and to allow the planner to make quick adjustments if any unintended effects of the road diversions are observed.
If the objective is to reduce car journeys, then you need to know how many cars are actually using the road, and when. You also need to assess which actions to reduce this are effective, such as legal speed restrictions, traffic calming, modal filters, behavioural messaging, road pricing, etc. Finally, you can match these interventions to the quality of the air that results.
To carry out monitoring, it is essential to consider all potential transport impacts of the construction works. This includes estimating how the development will generate changes to traffic volumes on the diversion routes, including by car, commercial vehicle, cycling, walking, or public transport.
Monitoring should assess not only the direct impact near the construction works, but also on adjoining transport infrastructure and identify any potential changes to roads, access or public transport services. Additionally, the assessment should evaluate the potential impact of the development on public safety, air quality, and noise levels.
Traffic counts provide critical data on traffic volume, speed, and direction, allowing for an accurate assessment of the impact of the construction works on the local road transport network. A Telraam network can quickly be established during the planning stages to get a baseline, as well as monitoring the impact of the work, and the result of the final designs.
It is crucial to involve early discussions between agencies, developers, local residents and planning authorities to save time and resources. In order to increase the chances of success at all stages of the process, from planning, approval, and delivery of the project to plan and budget including the integration of the new development into the local community, it is also useful to engage with local citizens to get them to participate in the process and ensure a positive outcome for everyone involved. Moreover, public tenders for (large) construction works, include good traffic management during construction works and engagement of the local residents as an award criterion. As such, setting up a Telraam network can make the difference between winning or losing a multi-million euro infrastructure contract!
