120 Start with the Crossings Because Crossings are: Hard to Integrate Hard to Upgrade Advertisers / Kickstarters Gapclosers A B Dutch Design Manual

121 Contextual Benefits Lowering intersection for comfortable ramps Eindhoven Hovenring benefits from the context

122 Think Modular! Economies of Scale by repeating parts 8 Bend Parts type 1 4 Bend Parts type 2 4 Connector Bridges Construction Modularity

123 Think Filter! Signage portals as high traffic filter Collision Loads Anti-Collision Portals - Cost-saving Filters

124 Seek Integration! custom aluminium extrusion profile LED deck lighting fixation point LED facial lighting Lighting Design Custom Handrail with Integrated Lighting

125 Seek Integration! Users Not intended visitors (Latin American mayor delegation 2017)

126 Seek Integration! Integral Design Integration of traffic lights, lighting and signage

127 Conclusions To develop bridges that satify all involved and their requirements: Analyse Involve Create Start Seek requirements thouroughly all from the start understanding & openess with the crossings - Modularity - Contextual Benefits - Filters - Integration & Optimization - Be open to practical custom new solutions. - Bridges are almost never standard solutions. - A custom solution can be best and cheapest.
