TECHNICAL DATA SHEET Traffic Light Indicator (Easy Read)
TECHNICAL DATA SHEET Traffic Light Indicator (Easy Read) Thermometer DESCRIPTION: The Traffic Light Indicator (TLI) is a single event temperature indicator that shows colour changes associated with that of traffic lights i.e. green to amber to red as the temperature increases. The colour changes are reversible. The product can be used to indicate two temperatures, the transition from green to amber and the transition from amber to red. In the example given in the specification below, these are at 50°C and 70°C respectively. The graphics are printed onto the reverse of a clear polyester using industry standard graphic inks. The event window is then created by a series of 6 coatings using propriety formulated temperature sensitive materials that change colour at designated temperatures which allows an instant response with a continuous readout. The distance from the event window to the edge increases water resistance. Once the coatings have been applied they are sealed in using a custom black coating which is applied across the back of the event window. An adhesive backing is then applied onto the strip and a UV inhibitor is over printed onto the face of the indicator before being cut to size. The colour changes are viewed through the clear, unlaminated side of the indicator. The protective release-liner can be removed for easy adhesion to a variety of flat surfaces. SPECIFICATIONS: Substrate: 100 Micron Clear Polyester Size: 52mm X 48mm Graphics: Black, White, Green, Amber & Red Temperature Profile: Below 50°C Event Window is Green in colour Between 50°C and 70°C Event Window is Amber in colour Above 70°C Event Window is Red in colour Accuracy: Materials are accurate to +/- 1°C Adhesive: Pressure Sensitive Acrylic with a moisture stable release liner Total Thickness: Approximately 245 microns INSTRUCTIONS OF USE: Peel indicator from release liner. -

Exploring Changes to Cycle Infrastructure to Improve the Experience of Cycling for Families

Abstract: Positive changes to the immediate cycling environment can improve the cycling experience through increasing levels of safety, but little is known about how the intrinsic benefits of cycling might be enhanced beyond this. This paper presents research which has studied the potential benefits of changing the infrastructure within a cycle network – here the National Cycle Network (NCN) in the United Kingdom (UK) – to enhance the intrinsic rewards of cycling. The rationale in this approach is that this could be a motivating factor in encouraging greater use of the cycle network, and consequently help in promoting cycling and active travel more generally amongst family groups. The project involved in-depth research with 64 participants, which included family interviews, self-documented family cycle rides, and school focus groups. The findings suggest that improvements to the cycling environment can help maintain ongoing motivation for experienced cycling families by enhancing novel aspects of a routine journey, creating enjoyable activities and facilitating other incidental experiences along the course of a route, and improving the kinaesthetic experience of cycling. -

Energy Efficient Lighting
Energy Efficient Lighting Overview According to the International Energy Agency in 2013 electricity for lighting consumed 20% of the output of the world’s power stations.1 For the USA the share of lighting was 15% in 20162. The use of energy efficient lighting is one of the simplest and most cost effective ways of reducing energy consumption. Efficient lighting programmes can be implemented in several areas within cities by: Figure 1: CFLs save up to 80% of energy compared to incandescent y Replacing traditional incandescent bulbs with compact fluorescent light bulbs light bulbs (CFLs). CC-BY-SA, Wikimedia Commons CC-BY-SA, Kübelbeck, Armin Photo: y Replacing old fluorescent tubes with efficient fluorescent tubes. y Replacing old magnetic ballasts with electronic ballasts in fluorescent tube systems. y Installing lighting control systems (motion and lux level sensors) y Using light-emitting diode (LED) technology wherever possible. This technology is developing fast and is getting steadily cheaper. LED’s are now able to replace most conventional lighting applications, such as traffic lights, down lighters, streetlights, security lights and even strip lighting to replace fluorescent tubes. It is anticipated that LEDs y Making streetlights more efficient e.g. by replacing mercury vapour will be used in most lights with high pressure sodium lights or LEDs that operate on around a third of the power.

Traffic Light Mapping, Localization, and State Detection For
Traffic Light Mapping, Localization, and State Detection for Autonomous Vehicles Jesse Levinson*, Jake Askeland†, Jennifer Dolson*, Sebastian Thrun* *Stanford Artificial Intelligence Laboratory, Stanford University, CA 94305 †Volkswagen Group of America Electronics Research Lab, Belmont, CA 94002 Abstract— Detection of traffic light state is essential for au- tonomous driving in cities. Currently, the only reliable systems for determining traffic light state information are non-passive proofs of concept, requiring explicit communication between a traffic signal and vehicle. Here, we present a passive camera- based pipeline for traffic light state detection, using (imperfect) vehicle localization and assuming prior knowledge of traffic light location. First, we introduce a convenient technique for mapping traffic light locations from recorded video data using tracking, back-projection, and triangulation. In order to achieve Fig. 1. This figure shows two consecutive camera images overlaid with robust real-time detection results in a variety of lighting condi- our detection grid, projected from global coordinates into the image frame. tions, we combine several probabilistic stages that explicitly In this visualization, recorded as the light changed from red to green, grid account for the corresponding sources of sensor and data cells most likely to contain the light are colored by their state predictions. uncertainty. In addition, our approach is the first to account for multiple lights per intersection, which yields superior results by probabilistically combining evidence from all available lights.

Homework Assignment 3
Uncovering the Secrets of Light Hands-on experiments and demonstrations to see the surprising ways we use light in our lives. Students will also learn how engineers and scientists are exploring new ways in which the colorful world of light can impact our health, happiness and safety while saving energy and protecting the environment. Activities (Have each activity checked off by an ERC student when you have completed it.) 1. Turning on an LED by connecting it correctly to a battery. 2. Optical Communication – Using LED flashes to remotely control electronic components such as televisions and to give music a ride on a light beam. 3. Observing the colors produced by different sources of light. 4. Light Saber – A discharge lamp that shows us that we are conductors just like wires and that can magically turn on a special kind of lamp without touching it. 5. USB Microscope – Using light to see small things, especially how displays work. 6. Pulse Width Modulation – Controlling light by turning it on and off.
