The Holbæk Motorway bisects the municipality east-to-west, and is a major roadway connecting Copenhagen through Roskilde to Holbæk; it extends all the way to the tip of Sjællands Odde, a peninsula sticking out into the Kattegat where a ferry connects to Denmark's mainland (the Jutland peninsula) at the town of Ebeltoft.

The municipality's good position in the traffic network has led to the development of Høje-Taastrup Transportation Center, which includes Carlsberg Brewery's huge bottle depot.

It offers an extensive system of hiking and bike trails through grass and marsh areas.

It connects to other parts of the greenway system, allowing one to seamlessly make a tour around the metropolitan area.

The station at Høje Taastrup is one of the largest in Denmark and offers excellent local (Copenhagen-area), regional (including Roskilde, Holbæk and Kalundborg), and national and even international train connections (for example, to Hamburg, Germany).

Hedehusene lies to the west of Høje Taastrup, on the stretch of railway connecting Copenhagen-Høje Taastrup-Roskilde.

King Christian IV wanted a house built for an official who would keep watch over entry gates on the road.

"The houses on the heath") Today the town has grown physically into neighboring Kallerup, Fløng, and Baldersbrønde.
