En samhällsekonomisk lönsamhetskalkyl för Cykellänken Ryd

Sammanfattning: During the winter of 2018, the bicycle path named Cykellänken Ryd was completed. The path extends from central Ryd to the city center of Linköping. According to the municipality of Linköping, Cykellänken Ryd is one out of two pilot projects which is meant to be evaluated and used to support the decision-making process of whether seven other planned bicycle paths is to be constructed. The municipality politicians have however, already decided for at least one additional bike path to be built, despite the lack of an evaluation of whether the pilot projects have been cost-effective. The purpose of this composition is to create a cost-benefit analysis of Cykellänken Ryd and estimate whether the project has been economically profitable. Based on the result, we have discussed whether another planned bicycle path is likely to be profitable. The bicycle path we will discuss is planned to be built between Hjulsbro and Linköping city center and is currently up for decision. In order to produce a result, an estimation regarding the positive and negative effects of the bicycle path has been made. By using ASEK and GC-kalk we have been able to estimate the monetary effects in order to compare the costs with the benefits. According to our calculations, Cykellänken Ryd is estimated to have a net-benefit of 61 501 142 SEK, and has therefore been profitable. We have also taken monetarily immeasurable effects into consideration. In order for the project to be unprofitable, these effects would have to exceed 61 501 142 SEK. The existing bicycle path between Hjulsbro and Linköping city center is currently used by 639 871 bicycle rides per year. The costs for the new bicycle path to Hjulsbro is expected to be higher than the cost of Cykellänken Ryd. However, due to the increased volume of cyclists it is also expected to produce higher benefits in the cost-benefit analysis. During the composition, we have had to make certain assumptions due to the lack of figures from the municipalities automatic bicycle counters and an absence of other information. Among others we lack the specific number of bicycle rides before the project were initiated, which is important to keep in mind.
