FOR URBAN AUTHORITIES

Test the plan before the council votes.

A clean air zone, new signal timings or a new line, tried on a simulated weekday of your own city before anything is built.

CITY TRANSPORT DEPARTMENTS

A clean air zone, tested before it is signed.

Paint the zone and choose the vehicles let in. Polycity runs a weekday of the city with the zone and without it, and the study shows what changes.

Ask for a clean air zone study

What the study shows

  • Nitrogen oxides and particulates, street by street
  • Trips that leave the car, and how they go instead
  • Residents better off, by income
  • Benefit and cost a year

Signal timing

When each light turns green.

Liivalaia and Pärnu mnt, lights every 90 s

  • Delay on the approach
  • Longest tailback
  • Grade of each approach
Polycity's editor on Tallinn: the signals where Liivalaia meets Pärnu mnt set to change every 90 seconds, 44 seconds of green for Pärnu mnt and 36 for Liivalaia.

A new line

Where the line should run.

A tram from Pronksi into Lasnamäe, 6.4 km

  • Boardings on the line
  • Jobs within 30 min
  • Trips by car
Polycity's editor on Tallinn: a new tram line of 6.4 km and 4 stops drawn from Pronksi in the centre out into Lasnamäe.

A closed street

How long works can close it.

Gonsiori closed, 1.7 km

  • Trips that went round
  • Hours lost
  • Lines cut back
Polycity's editor on Tallinn: the whole 1.7 km of Gonsiori closed, all day.

New homes

Where new homes can go.

800 homes in Lasnamäe by the airport

  • Trips they add
  • Streets jammed at the peak
  • Wait at the stop
Polycity's editor on Tallinn: a site of 10.1 hectares drawn in Lasnamäe north of the airport, with 800 homes and 1,840 residents.
