Exploring Color Contrast: A Natural and Simple Measure to Protect Vulnerable Road Users

Marisa CruzGAIT 2015Turkish-EU Partnership for Sustainable Transportation Seminar08-09.10.2015

How do you move around town?

Half of the world’s road traffic deaths occur among vulnerable road users

• Motorcyclists: 23%

• Pedestrians: 22%

• Cyclists: 5%

Global megatrends demand innovation in road delineation

MEGATRENDS

Urbanization & accessibility

Life cycle costs & climate

protectionMobility & smart

Need for innovation and creativity!

Growing population & increase in accidents

At the end of 2008, half of the world's population was living in urban areas

Urbanization Projection

According to the UN Department of Economic and Social Affairs:

• At the end of 2008, half of the world's population lived in urban areas

• Urban areas are expected to absorb population growth

• Until 1970, Tokyo and New York were megacities

• In 2011, the world counted 23 megacities!

• By 2050, it should be between 60-100 megacities!

Sustainable transportation in megacities is a big challenge

Different transport modes tend to be part of urbanization

• High population density:o Megacities: 4,900 per Km2

(on average)o Amsterdam: 493 per Km2

• Increase in vehicle ownership

• Reduced travel speed, increase in congestion and pollution

Reminder: cyclists and pedestrians face a particular risk

Half of the road traffic deaths occur among vulnerable road users:

• Motorcyclists: 14%

• Pedestrians: 28%

• Cyclists: 3%

Color contrast brings flow to transportation

Cities have tested exclusive bus/bicycle/pedestrian lanes and are actively looking for cost efficient solutions with an immediate positive impact

Increased visibility means:

Increased Safety

• Separates fast from slow moving transportation

• Color minimizes intrusion into special lanes and hereby improves safety of users

Increased Economic Incentive

• Reduced travel times, more fuel efficient transportation and increased ridership.

• Protection of vulnerable road users

Denver, USA

Crosswalk Safety in Denver, CO

• Several pedestrians a year were injured at this Denver crosswalk before installation of cold plastic area marking

• High visibility color area marking was used to decrease that number by 50%

Santiago, Chile

Priority bus lane in Santiago, Chile

Solution with cold plastics color contrast:• Form stability without cracking at all weather

conditions• Color stability• Bus traffic flow improvement of up to 50%!

Challenge:• Combat growing urban traffic congestion • Make regular bus services faster and more reliable• Long lasting material required!

BRT based on Cold Plastic Road Marking

New York, USA

Reshaping bike lanes in New York City

Various materials were tested during a 1 year trial phase. The conclusion:• City beautification and effective

traffic delineation

Challenge:• Combat growing urban traffic congestion • Improve safety of bikers• Long lasting material required!

Bali, Indonesia

Red box for motorcycles, Bali-IndonesiaCase study by the Institute of Road Engineering*1

Motivation of the application:

• A motorcycle is the most used mode of transportation in Indonesia

• Traffic conflict between motorcycles and other types of vehicles in intersections

Approach:

• Creation of a designated area in the form of a red box for motorcyclists when the traffic light is red

• Average improvement of conflict = 40%

Bali climate*:

• Temperature of 30°C and 85% humidity on average
