TRA(GG)IC.how did London deal with the congestion problem?

THE MOTIVATIONThis.

The internationally accepted density of vehicles/km road is approximately 300; in Bombay, the density/km has already crossed 1,000 vehicles

“

BACK TO LONDON. WHAT IS THE CONGESTION CHARGE?

- 2003 onwards, 4 wheelers have had to pay a daily ‘charge’ if they want to drive in central london

- The idea was to improve traffic flow

- Reduce pollution

- Generate revenues to improve road safety and public transport

QUESTIONS

- Did the congestion charge do the trick?

- What worked? What didn’t?

- What insights could be gained out of it that could potentially be applied to the Bombay context

TARGET

- People of Bombay. Just to start a conversation

INSIGHTS

- The congestion charge seemed to have helped in the inner city. It helped free up space for reallocation

- However, reduction in traffic even before the CC & in non-CC areas suggests that, other factors may also be responsible, such as recession, higher fuel prices, improved bus & cycle mobility

- The revenues generated were invested in improvement of bus & cycle mobility, which further contributed to reduction of congestion.

- IMPROVING THE MOBIITY OF A CITY DEPENDS OF A NUMBER OF FACTORS WHICH ARE ALL CO-DEPENDENT

NEXT STEPS

- Design information to accomodate secondary levels of information. Many variables contribute to a city’s mobility and all of them need to be understood in relation with each other in order to get a clearer picture.

- Which would mean revisiting the UI

- Which would mean revisiting the visual language. More coherence. Stronger visual metaphors
