Walking can be hazardous. But “puffin” crossings are one way to make pedestrians safer. Photo via webax. This post was inspired by a discussion on a sustainable transport listserv about which kind of pedestrian crossings should be installed in certain intersections in Indian cities. Most of the animal-inspired crosswalks are of British origin and are mostly found in the U.

By the time the Gregorian calendar was adopted in Britain, it was 11 days ‘ahead’ of the old Julian calendar it replaced. John Owen Smith Home Page. I hope you find this list helpful and informative — even entertaining at times! It represents the combined efforts of a number of contributors, but none of us would want you to think that it represents all the important events in British history, or have you believe that everything you read here is necessarily accurate or undisputed.

Nor, I might add, do we imply that all the inventions, etc, listed here are British ones — but it can be useful, for example, to know whether your ancestor or the character in that historical novel which you’re writing could have been using a particular item at the time they were living. At least, I think so. We have done our best, and hope that you will take the list in that spirit.

First electric traffic signal installed

Lester Wire, with his two color traffic signal The traffic signal was first invented in — by a Detroit policeman named Lester Wire — as a two-color, red-and-green light with a buzzer to warn pedestrians ahead of the impending transition. In , this basic design was modified by another policeman named William Potts to include the tri-colored red, amber, and green lights widely used today. This simple, three-color icon has endured for nearly a century with relatively little change, save for the incorporation of modern technologies such as automatic timers, diode lights and motion sensors.

Did you know that France issued the world’s first driver’s licenses 15 years before the Henry Ford unveiled the Model T in ? Or that Britain adopted speed limits in the mids? Or that the earliest “No Parking” zone dates back to around B. From license plates to car insurance, many of the laws and practices that drivers take for granted today came about at the automobile era’s dawn in the late s — if not earlier. Experts don’t necessarily agree on when some of today’s automotive laws and practices initially appeared, but the dates that follow reflect the earliest instances documented by credible sources.

The first traffic signal arrived decades before gas-powered autos did, appearing near London’s House of Parliament in to regulate pedestrians, horses and horse-drawn wagons. It consisted of red, yellow and green gas lights operated by a police officer, but only lasted a month before a leak caused one of the lamps to explode, seriously injuring or killing the operator — accounts differ. The first electric traffic light was invented in by a Utah policeman named Lester Wire.

Installed in Salt Lake City in , it had red and green lights that a police officer manually operated. Automated operation began in The earliest speed limits harken back to at least the midth century, often backed by railroads and carriage-makers that wanted to stifle development of steam vehicles and later of gas-powered cars.

For example, Britain’s Locomotive Act restricted early vehicles to just 10 miles per hour in rural areas and 5 mph in urban ones. An revision was even stricter, setting speed limits at 4 mph in the country and 2 mph in cities and towns. Drivers also had to have someone to walk in front of their cars with a red flag.

This Traffic Signal Timing Manual TSTM is intended to be a comprehensive guide to the traffic signal timing engineer and technician on traffic signal control logic principles, practices, and procedures. The TSTM represents a synthesis of traffic signal timing concepts, analytical procedures, and applications based on North American practice into a single publication. The manual also presents a framework for evaluating traffic signal timing applications related to maintenance and operations.

This manual is intended to complement policy documents such as the Manual on Uniform Traffic Control Devices, and is not intended to replicate or replace the Highway Capacity Manual, national or local engineering documents on signal timing, nor is it intended to serve as a standard or policy document. Rather, it provides a summary of practices intended to help practitioners in the timing of traffic signals.

The origin of traffic control signals can be traced back to the manually operated semaphores first used in London as early as The first traffic signal in the United States was developed with the objective to prevent accidents by alternatively assigning right of way. The traffic signal has changed significantly since its early development.

The History and Meaning of Colored Traffic Lights

For the most part, we take them for granted. But when a power failure temporarily puts out the lights, the resulting gridlock reminds us how much we rely on them to keep our roads safe and traffic flowing. In contrast, back in the days before the arrival of the automobile when life moved at a more leisurely pace, there was little in the way of traffic controls.

Even whether one should keep to the left or to the right was uncertain.
