Proposals for improvements

1. Manglende samordning

mod vest

A) Der bør (gen-)indføres en samordning med kommunens anlæg mod vest.

2. Ingen signaler for

cyklister

A) Signalbilledet for cyklister i A1-retningen kan forbedres, f.eks. ved at

opsætte at alm. trelys på masten til højre for cyklisternes stoplinie.

3. Ingen højtsiddende

signaler for ramperne eller

for venstesvinget fra vest

A) Der kan suppleres med højtsiddende signaler. Der er dog ikke

konstateret problemer med synligheden af krydset.

4. Ingen repetition af

cyklistsignalet fra øst

A) Der kan suppleres med et cyklistsignal på midterhellen i rampen fra

nord.

5. Trafikstyring A) Der kan overflyttes lidt tid til hovedretningen ved at indføre trafikstyring

af grøntiden for ramperne (særligt den sydlige) og venstresvinget, der –

trods den generelt høje trafikbelastning – periodevis ikke udnytter grøntiden

fuldt ud.

Conclusion

There are discrepancies or errors found in the majority of

traffic signal installations

In most cases it is possible to propose small or larger

adjustments – with great effects

Little cost –> great return
