The Viva traffic sensors play an essential role in helping us to measure the impact of our range of sustainable travel initiatives here at Milton Park.  The data provided by the sensors is very helpful when it comes to justifying investment in things like cycling infrastructure and related projects and also in the continuing monitoring of vehicle traffic on our site.  It gives us credibility when we are talking to stakeholders, especially local authorities. The sensor data also acts as a counter-check of our travel survey statistics and provide a framework for our green travel planning.
