Stockholm	11. Danvikstullsbron	N	4,020^c	Road marking, white line	4.9	2.5	2.4
Linköping	12. Vallaskogen	N	2,830	None	3.1	—	—
Linköping	13. Haningeleden	N	1,120	None	2.9	—	—
Linköping	14. Hunnebergsgatan	E + N	3,390	Different road surfacing: Paving/ stones	6.6	2.5	2.0 + 2.1
Linköping	15. Malmslättsvägen, norra	E + N	1,780	Road marking, white line	5.1	2.4 + 0.4	2.3 − 0.5^d

^aE = existing measurements, N = new measurements. Design features are included for the sites selected for new measurements.

^b Based on existing measurements or from new measurements for sites 11–13.

^c Based on the period August 25–19, 2014.

^d Lampposts intruding on the pedestrian path and reducing the width.

Figure 1. Average directional speed (km/h) of bicyclists passing the measurement sites. Based on weekdays (Monday to Friday). Direction 1 (dir. 1) is representing the direction towards the city center and direction 2 (dir. 2) is the opposite direction. The sites 16–19 have no information of directional average speeds. Blue bars = Stockholm, green bars = Linköping, orange bars = Eskilstuna.

Table 2. Results of analysis of variance applied to speed data from site 20.^a

Month	Mean values (km/h)		January	February	May	July	September	December
January	13.8			.6154	<.0001	<.0001	<.0001	<.0001
February	13.8		.6154		<.0001	<.0001	<.0001	<.0001
May	16		<.0001	<.0001		.1687	<.0001	<.0001
July	16.1		<.0001	<.0001	.1687		<.0001	<.0001
September	15.7		<.0001	<.0001	<.0001	<.0001		.0008

^a Adjusted mean values for selected months in 2015 and P values from pairwise tests. All months are shown in Table A2). Nonsignificant results are shown with gray shading. An overall significance level of .05 was used, but each P value was compared to a Bonferroni-corrected value of .00076.

Figure 2. Adjusted mean values of speed at site 20 for type of day and time of day, 2015. The error bars represent 95% CI. Results from analysis of variance.

Figure 3. Speed distribution in box plot, divided by direction. Sorted by average speed. Based on weekdays (Monday to Friday). Box = 15th and 85th percentile, respectively. Line in box = The median speed. Cross in box = Average speed. Whiskers limitations = 5th and 95th percentile, respectively. Dots = Extreme values. Direction 1 (dir. 1) is representing the direction towards the city center and direction 2 (dir. 2) is the opposite direction.
