The 26th JCT Traffic Signal Symposium & Exhibition

September 15-16, 2021

Nottingham, UK

We are excited to be Bar Sponsor on the 26th JCT Traffic Signal Symposium & Exhibition, join Gav Jackman on our Stand E1

For 25 years the JCT Symposium and exhibition has been bringing traffic signal practitioners together with manufacturers and to maintain a sense of community amongst signals engineers. It is intended to run as an affordable conference that is accessible to as many people as possible, regardless of experience and that encourages the exchange of knowledge, experience and good practice. Over the past few years, the symposium has consolidated its position as the UK”s best conference event for traffic signals.


The Symposium & Exhibition runs over two days, and is preceded by the MOVA user group. It mixes conference style papers, the principal manufacturers, networking opportunities and organised social events in the evening. As far as content goes, the emphasis is on the signals community itself and JCT seeks submission of papers and presentations from working signal engineers, manufacturers and suppliers. The broad appeal of the programme means that papers are also welcome from policy makers, interest groups, and academics. If you would like to share your experience with the signals community then please let us know and we will do everything we can to help you including subsidising attendance at this event.

Aimsun on the JCT Symposium

Gav Jackman will present the paper “Predicting and comparing traffic management response plans to mitigate tail pipe emissions in real time.”

Description:

NEVFMA is the UK’s first fully operational, county-wide predictive model for the Highways England strategic road network in Oxfordshire. The model predicts not only traffic but also emissions, with a real-time, traffic-linked pollution dispersion model.  This delivery uses a large-scale model of the county of Oxfordshire that is connected in real-time to ITS systems and uses traffic simulation to reduce congestion and harmful, traffic-related emissions.

 

The model was delivered for the Network Emissions/Vehicle Flow Management Adjustment (NEVFMA) project, funded by Highways England and delivered by Aimsun in partnership with EarthSense, Siemens Mobility and Oxfordshire County Council. NEVFMA uses the Aimsun Live solution to generate short-term predictions for traffic and nitrogen dioxide (NO2) dispersion to help traffic centre operators make the most effective traffic management decisions.

 

Initial Analysis at the end of 2019, of the 57% of the days evaluated emissions exceeded the annual legal average. On 65% of the days evaluated the system recommended a different traffic management strategy than a do nothing scenario, to bring Emissions back in line, and on those occasions, emissions were predicted to be on average 5% lower if a chosen strategy was deployed.

 

Further data has been analysed since April since Uk traffic bounced back with lock down easing, and further data will be analysed during the summer in time for the conference!
