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

Color contrast brings flow to transportation
Page 8
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%

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!

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

Tailor-made Intersections
• Pedestrian safety• Attention of drivers
Public Spaces
• Transforming underutilized areas• Regaining public spaces
Safe Biking
• Rising trend• Multi-modal pathway
Speed Reduction
• Optimum costs-benefits• Behavior change Priority Bus Lanes
• Fuel consumption reduction• Traffic conflict reduction
Accident Black Spots• Audible warning • Accidents reduction

• Reinvent road safety• Change behavior• Anywhere in the world
There is a lot to be done!
Take away message: Set the scene to overcome urban millennium challenges in road safety
