One Hundred and Twenty Volt Signal Systems Utilizing Wireless Communication for Temporary Installations (Poster)

In our province, aging infrastructure and severe flooding over the past two decades have us replacing or undertaking substantial repairs to our bridge network. These replacements or repairs typically require a two lane highway to operate as one lane for both directions necessitating some form of traffic control. Traditionally, trailer mounted Portable Traffic Signal Systems (PTSS) powered by 12 volt DC batteries recharged by solar panels are used in these applications. The trailers are easily deployed and can be setup on short notice. The objectives of this project were to design a system: which can be powered by a reliable stable power source; that will utilize the same controller as the solar powered 12 volt DC system to reduce spare part inventory; where the control signals at the project start and finish points can be 500 to 1000 meters apart; which does not require cabling between the control signals at either end of the project; which will keep operating during snowy, cloudy, cold weather conditions; that is easily installed and in a short time frame; where one pole can be utilized to support two traffic signal fixtures, a hydro service, vehicle detection equipment, traffic signal control box and street lighting; and where the signals at each end of the project are monitored for conflicting indications as well as lamp outs for safety reasons.
